Yan Yutang (1880~1958) light algae. Originally from Wu County, Jiangsu Province, he is a resident of the Yan family in western Hu. At the age of 19, he entered the British business husband Mao Foreign Firm as an apprentice, succeeded as the personal assistant of the foreign firm owner Piwens, and later entered the Gongxing Iron Works as a street runner and deputy manager.
In the 28th year of Qing Guangxu (1902), he co-founded a small workshop with people in Taihe Street, Yangshupu, named Dalong Iron Factory, engaged in textile machine repair. Guangxu 32 years of independent operation of Dalong, and undertook the production of Shanghai British businessmen and other waterworks water pipe gates, imitation of agricultural machinery. From the first year of the Republic of China to the third year (1912~1914), it was mainly used to repair textile machine parts, and the transmission device of the American merchant Hengfeng Foreign Textile Machine and Flour Mill was made on behalf of the American merchant Hengfeng Foreign Firm, and the factory was relocated to Pingliang Road. During World War I, the Taroon machine repair business flourished. Following the construction of the factory in Dalian Bay Road, Zi Qingxiang served as the director of the factory. There are more than 300 workers, and the capital is 20 times that of the time of the start-up.
In the 13th year of the Republic of China, it purchased more than 60 acres of land on Guangfu West Road (the current site of Dalong Machine Factory), built a factory, and the business also developed from textile machine parts repair to machine manufacturing. When the Republic of China moved into the new factory in 15 years, there were more than 200 mother machines and 1300 employees. In the spring of the 14th year of the Republic of China, it cooperated in the lease of Suzhou Sulun Yarn Factory, established Guangyu Company, managed Dalong and Sulun 2 Factories, and implemented cotton-iron joint venture. In the 19th year of the Republic of China, the second factory and weaving factory of Sulun were built in Suzhou, and at the same time, a full set of power generation equipment was ordered from abroad and the power plant was run by itself. The following year, his sixth son Qingling returned to China from Germany, presided over the Business of Dalong, and hired foreign experts to manage the factory and produce complete sets of cotton spinning machines. In the 23rd year of the Republic of China, it acquired Shanghai Longmao Spinning Factory, changed its name to Rende Spinning Factory, and invested in Changzhou Minfeng Spinning Factory, Qishuyan Tongcheng Wool Spinning Factory and Zhengzhou Yufeng Spinning Factory, becoming a famous industrialist in Shanghai and southern Jiangsu.
After the Outbreak of the Pacific War in 1941, the Japanese took over the Shanghai Concession. Taili was forced by the Japanese army to produce arms, the original production equipment was seriously damaged, and the business began to decline. In the case of unfavorable production, Yan Yutang set up another Defu Machine Factory, which specialized in hardware speculation in the name of the fake machine factory to assist Taili. In addition, Yan Qingling also used his funds to open the Lida Heavy Industry Bank in 1943, and turned to speculation such as usurious demolition, real estate, materials and stocks for huge profits.
After the victory of the War of Resistance Against Japan, Dalong, Sulun and Rende were all accepted by the Nationalist government, and in 1947 the three factories were redeemed through various activities. After the Yan family redeemed the three factories, although they expanded or added equipment respectively, under the monopoly of the market by the United States and Chiang Kai-shek Capital, the production of the factories was sluggish and paralyzed.
From 1947 to 1949, the Yan family also jointly established the Suzhou Spinning Factory in Suzhou and the Yisheng Spinning Factory in Hong Kong. But the development is not fast, and the profit is limited. In this case, they are still looking for a way out of the speculative business. During the above period, Yan Qingling opened a Taili office in Shanghai, using the funds of Dalong, Taili and other factories to purchase foreign exchange at official prices, import hardware and equipment, and earn more than 10,000 gold from them.
In the 47 years from the establishment of Dalong in 1902 to 1949, Yan Yutang developed from a lane workshop owner into an entrepreneur with three modern large factories and several small and medium-sized spinning mills, and had banks and real estate, thus building the pyramid of Yanjia capital.
In the winter of 1948, on the eve of the liberation of Shanghai, Yan Yutang and Yan Qingling, attached themselves to the Kuomintang Chiang Kai-shek regime, stole some of the machines of their factories, and fled to Taiwan with funds to follow Chiang Kai-shek, and Yan Qingling came forward to open the Yulon Machine Factory in Taiwan. The Yulon Iron Factory and the Taiwan Dollar Textile Factory were opened, and the Yulon Group, which owns automobiles, textiles, machinery, finance and other industries, was gradually formed, and was one of the top ten consortiums in Taiwan.
In November 1958, Yan Yutang died of illness in Taiwan at the age of 78.
Yan Qingling, the fifth son of Yan Yutang, set foot on the island of Taiwan with his wife Wu Shunwen as early as 1948 under the arrangement of his father Yan Yutang. Yan Qingling, who was a German doctor of mechanical engineering, was almost blank in Taiwan's auto industry at the beginning, and because of this, Yan Qingling and his wife planned to make a difference in the automotive industry. In 1953, Mr. and Mrs. Yan Qingling founded Yulon Automobile in Taipei.
In 1981, Yulon founder Yan Qingling died, yan Kaitai's mother Wu Shunwen, inherited his father's business, served as the chairman and general manager of Yulon, becoming the core figure of the family business generation. Wu Shunwen was once known as "China's first female industrialist", and the Taiwanese media often called her "Textile Queen", "Automobile Queen", and "Iron Lady".
Today, in Taiwan, there are public welfare funds named after Wu Shunwen, such as the Wu Shunwen Journalism Scholarship Foundation and the Wu Shunwen Neuroscience Development Foundation. Wu Shunwen died in 2008, was once known as Taiwan's richest woman, she is still working at the age of 90, and she led the Yulon conglomerate, which has been ranked among Taiwan's top ten enterprises for consecutive years, and she is also the champion of Taiwan's 1985 annual tax rankings.
Born in December 1913 in Wujin, Jiangsu Province, Wu Shunwen, a female leader of the Yulong Department, graduated from the Department of Literature of St. John's University in Shanghai and received a master's degree in literature from Columbia University in the 1950s.
Speaking of Wu Shunwen, the mainland may feel a little unfamiliar, if you mention her cousin, it is a well-known figure, he is the former vice chairman of the National People's Congress, the outstanding leader of the Jiusan Society, and the academician of the two academies, Wu Jieping, and Elder Wu is Yan Kaitai's cousin. Born in 1917, Wu Jieping was 4 years younger than Yan Kaitai's mother and cousin Wu Shunwen.
Wu Jieping's father was named Wu Jingyi and his mother Was Zheng Xia; Wu Jieping's grandfather was named Wu Fengwu, Wu Jingyi was the second son, and the eldest son was Wu Jingyuan, that is, Wu Shunwen's father and Yan Kaitai's grandfather; the third son was named Wu Jingyu.
Wu Jingyuan, also Wu Jieping's great uncle and Wu Shunwen's father, was born in 1875 and served in Cilizhi County, a direct subordinate prefecture, and in 1911, after returning from Hunan after ending his political career, he engaged in business. Wu Jingyuan is not only an industrialist in the modern textile industry, but also one of the founders of Zhonghua Bookstore.
Borrow a boat out of nowhere
Yan Yutang, born in Shanghai, is originally from Yin county, Zhejiang (The Character of the Forty-fourth Volume of the Shanghai Tongzhi - Chuan Lord), whose ancestors moved to Shanghai in the middle of the Qing Dynasty and lived in the North Yan Family House on Zhenning Road, Yuyuan Road (Figure 2). There are other versions of the Ancestral Home of the Yan Family, one saying that it is Wuyuan County in Anhui (The Thirty-eighth Chronicle of Changning District- Character Biography), and the other is Wu County in Jiangsu Province.
Most of the Yan family ate foreign firms, and his father and uncle were both compradors of foreign firms. Growing up in such a family, Yan Yutang had a natural interest in comprador careers and business activities. He also showed his talent early in English learning. The father, Yan Jieting, saw that his son was a talented man, and hired a foreign teacher for him to teach him language and Western culture.
Yan Yutang (1880-1958)
By the age of 19, Yan Yutang entered her husband Mao's foreign firm as an apprentice under the introduction of his uncle, and later served as the personal assistant of Pierce, the owner of the foreign firm, and soon he became familiar with all the business of the foreign firm. Sometimes in the absence of the senior class, he can also socialize decently, reflecting the ability to be independent.
After working in the foreign firm for two years, Yan Yutang entered the Gongxing Iron Works as a creditor. Gongxing Iron Works is a private machinery manufacturing plant, co-founded by Xu Fushou, Du Abao and others. Just a few years after the establishment of the factory, the main business is to repair small steamers, textile machines, etc., but also to undertake the business of turning iron and sand. At that time, the number of foreign ships coming to Shanghai was increasing, and the repair business was busy, which was a good opportunity for the development of the iron factory, but the Gongxing Iron Factory was difficult to obtain large orders because there was no foreign language talent. Yan Yutang is familiar with this, and after he entered the factory, the business volume soared.
At this time, Yan Jieting saw that his son Yan Yutang was doing a good job running the street, so in the twenty-ninth year of Guangxu (1903), he and Qian Xinru (Qian and Yan were relatives, that is, Yan Yutang's father-in-law, opened a rice shop on Changzhi Road in Hongkou, a bit lisheng), and the blacksmith Chu Atu jointly opened the Dalong Iron Factory, so that his son Yan Yutang set up his own portal and served as a manager. When the Dalong factory was first established, in Meijia Lane, Taihe Street, Yangshupu, two bungalows were leased as workshops, and there were only 7 workers and 4 apprentices. At that time, the factory mainly repaired small machinery parts for foreign merchant ships, or repaired spare parts for silk reeling factories and ginneries.
Soon, the Dalong factory moved to Pingliang Road, renting Yan Jieting's 12 tin wood plank bungalows as a factory building, and there were only 8 belt lathes in the factory, 1 each of the bull head planer and the gantry planer, powered by a 20-horsepower water stove engine. At this time, the number of workers in the factory increased to 50, and most of them were apprentices.
Dalong Iron Factory Workshop
The machine factory is mainly engaged in textile machinery and external engine parts repair projects, Yan is the manager, responsible for foreign affairs. Yan Yutang has always kept his eyes on the Huangpu River, and has also equipped two small tugboats to provide door-to-door services for foreign boats, and the number of patrons is increasing. In addition to the repair of external engine parts, the repair business of other manufacturers has gradually been contracted, and the long-term customers who have increased successively include Yongmao Gin Factory, Sino-US Flour Mill, Nissho Yunlong GinNing Factory, Shangzengyu Flour Mill, etc., and the business is booming.
In 1907, Yan Yutang bought out Chu Xiaomao's shares, turning Dalong into a wholly-owned company At this time, more and more manufacturers doing outer wheel repair business, profits were getting thinner, while the domestic cotton textile industry was becoming more and more prosperous, and the corresponding textile machinery business was rarely produced by local production, and it was imported by foreign countries at high prices. Not only is the purchase price high, but it is also inconvenient to repair. Yan Yutang saw this business opportunity and announced. Abandon the outer wheel business and shift the production business to the repair business of textile machinery parts.
At this time, Dalong not only began to take shape in scale, but also had a strong technical force. Although it is not completely self-made for a while, the level of imitation and repair is the best in the industry. Yan Yutang used his business liaison strengths to obtain two major orders from the British merchant Hengfeng Yang and the Japanese internal and external cotton companies. Agent processing can not only justifiably learn manufacturing technology, but also solve the most practical business volume problem. Dalong took the two major foreign customers as the starting point and established business relations with more than 40 customers, which enabled Dalong to embark on a stable road of development.
In the 1920s, the Tai Lung Iron Works were all over the place
After the business development of Dalong Machine Factory, the original scale could not be adapted, and in 1914, the additional factory building along Pingliang Road was completed, and the number of workers had increased to more than 100. In 1914, the First World War broke out, the Western powers were involved in the whirlpool of war, the long-stifled Chinese national industry was revived, and the textile industry developed rapidly. Yan Yutang immediately realized that Dalong would also gradually derail with foreign enterprises in China and turn to cooperation with national industries. Therefore, he contracted the machine repair task of the Rong brothers Shenxin Factory. At the same time, Dalong organized technical forces to trial-produce some textile machines, laying the foundation for the manufacture of the whole machine.

"Do what no one else can do"
The establishment of modern machine industry, first of all, the machine. However, in modern times, China's own machine manufacturing industry is very backward, and traditional iron workshops cannot undertake the mission of manufacturing and maintaining large-scale production machines. Whether it is the military and civilian industries in the western period or the period of great development of national industry in the early days of the Republic of China, machinery and equipment are basically imported by Britain, the United States, Germany, Japan and other countries through foreign companies. Although the national machine manufacturing industry is making slow progress in learning and imitation, it still cannot meet the needs of the establishment of industries.
Even the forerunners in the national machine manufacturing industry such as Dalong and Qiuxin Machine Factory (the machine manufacturing factory founded by Zhu Zhiyao) were mainly engaged in the repair business of machines for a long time. Although Yan Yutang has done his best to receive many large orders from foreign companies, it is still difficult to achieve the great development of the machine factory. In order to open up channels, Yan Yutang always said: "Take the work that others are unwilling to take, and do the work that others can't do." "The work that others do not want to take is relatively easy to do, Dalong factory for other machine factories do not want to undertake small work and odd jobs always come not to refuse, timely for the factory to solve problems, won a good reputation, Dalong's reputation continues to increase, but also won more long-term orders."
But if you want to "do what others can't do", you need technical strength to back it up. The new machine is not just a simple object, attached to the machine is the advanced design ability and production technology, is the technical development and application team with machine manufacturing skills. Yan Yutang knows that if Dalong wants to get rid of low-level machine repair and turn to high-level machine manufacturing, the most important thing is to cultivate its own technical team and take the road of technological self-reliance.
Yan Yutang established a strict apprenticeship system in Dalong to ensure the technical level of front-line workers and achieve the purpose of "attaching importance to technology, quality and quantity". Dalong selected a group of skilled, hard-working old technicians as masters, and apprentices must be strictly selected before entering the factory. Apprentices study for three years, following the master as an assistant during the day and learning the relevant theoretical knowledge at night. Apprentices are eliminated and may be dismissed at any time if they do not perform well. Outstanding apprentices can be left as workers by the factory after completing the division, and some are gradually selected as foremen, foremen and even factory directors. According to statistics, the total number of technicians and managers trained by Dalong is about 10,000, and these technicians not only strengthen the technical strength of Dalong, but also become an important part of the technical team of China's early machine manufacturing industry.
Dalong relies on the technicians of our factory, from the repair of parts, the imitation of accessories and gradually move towards the manufacture of the whole machine. In the early stages, it is mainly to repair simple accessories and machine failures, and then repair more complex textile machines and engines. In the repair process, Dalong not only pays attention to training technicians to carry out general empirical operations, but also requires technicians to master mechanical principles and improve design capabilities. In the process of manufacturing the transmission device of the textile machine for the British merchant Hengfeng Foreign Firm, the Da Long technician learned many key technologies from the design solution provided by the foreign firm. Dalong imitation quality is excellent, quite praised by users.
At that time, the most important business was the repair and manufacture of textile machinery. Yan Yutang saw that many domestic textile factories import machinery and equipment from abroad, which is not only expensive, but also has high maintenance costs. Such business opportunities are not only the loss of the national textile industry, but also the fault of the machine manufacturing industry. He has never given up the dream of whole machine manufacturing. After repeated efforts, by 1922, the Dalong Machine Factory finally successfully trial-produced looms and went public for sale. This loom is manufactured in accordance with the Japanese Toyota-style loom, with reference to the British and American looms and combined with the requirements of the domestic use. The success of the loom shows that the technical level of Dalong has reached a new level.
Yan Yutang also introduced a group of new technical experts, set up technical research and development institutions, and comprehensively improved the mechanical design and manufacturing level of Dalong. In 1928, Dalong yan hired mechanical expert Huang Puqi as the manager and engineer of Dalong Machine Factory, in charge of the production and business of the whole plant. Under the auspices of Huang Puqi, the factory set up a mechanical physics laboratory. In 1932, Yan Qingling, the sixth son of Yan Yutang, returned to China and was appointed as the director of the Dalong Machine Factory.
Yan Qingling carried out comprehensive reforms in production technology and process organization. He hired Lian Zhongjing, who was good at internal combustion engine manufacturing, as an engineer, and also hired two German engineers to form the chief engineer's office together with the original technicians, and made a series of improvements in casting, machining, measuring tool manufacturing, heat treatment and other aspects. After hard work, Dalong has gradually been able to imitate the whole machine and design various types of machinery and equipment from the imitation of mechanical parts, and realized the assembly line production.
In 1932, the office building of the Da Long Iron Factory
By the 1930s, The Japanese-style fine yarn truck, sizing car, drum car, lengthening machine, baler, British-style unpacking machine, cotton opening machine, cotton machine, flower rolling machine, cotton cleaning machine, carding machine, seven-eye parallel strip machine, and also manufactured a 120-ton pressure oil press for spinning bales and dyeing machines, completed the manufacture of a complete set of cotton textile machines, and became the pride of the Chinese merchants' machine manufacturing industry.

The extension of the industrial chain is a matter of life
Dalong's technical level is constantly improving, but the market competition is more brutal. After the end of the First World War, foreign capital made a comeback, resulting in the closure of many cotton spinning enterprises developed during the war, and the machine manufacturing industry also suffered collateral pain. Due to the low overall level of the national machine manufacturing industry, Chinese textile enterprises, in addition to relying heavily on local enterprises in maintenance, still import complete sets of equipment from abroad.
Yan Yutang's dream is to establish a first-class machine manufacturing enterprise with advanced technology and independence, but under realistic conditions, the road of simple technological self-improvement is not easy to go on. In 1922, the Dalong Machine Factory successfully tried to make looms, but the new products were marketed and promoted, because Chinese merchants despised domestic products, and the products were not selling well. Some manufacturers have purchased several units on their friendship with Yan Yutang, but they have also abandoned them. The promotion of the free machine is not good.
Yan Yutang was not reconciled, and he made a bold decision: no one bought, he built his own spinning factory, made his own sales, and set an example. In 1925, Yan Yutang rented the Suzhou Sulun Spinning Factory, which had been losing money for many years, and renamed it Sulun Qiaji Spinning Factory. After the full takeover of Su Lun, the original machine was completely renovated by the Da Long Machine Factory, and the second factory of Su Lun and a weaving factory were added to the textile machines of the Da Long Machine Factory.
After the re-operation of Sulun Spinning Mill, due to the low cost of machine purchase and maintenance, the product cost is much lower than that of other textile factories, and the product texture is also very good, so it is contrary to the previous sluggish situation, and the profits have been abundant for many years, which is beyond the reach of the general spinning mills at that time. Yan Qingxiang, the eldest son of Yan Yutang, concluded that the Sulun Spinning Mill "cannot but rely on Dalong in terms of public works and talents, such as the repair and replenishment of machines, etc. If there is no Dalong, it is not convenient, and talents are not the long-term training of Dalong, and there is absolutely no such application." The success of Sulun Spinning Mill means that Yan Yutang's "cotton-iron joint venture" corporate strategic plan has initially succeeded.
In 1927, Yan Yutang reorganized and established The Guangyu Company, which managed the two factories of Dalong and Sulun, and served as the general manager, with the eldest son Yan Qingxiang as the deputy general manager. From 1930 to 1931, Su Lun Factory sold more than 30,000 bales of yarn, 110,000 horses of cloth, and the annual profit reached 400,000 taels, and the sales channels of Dalong products were also solved. In 1934, Yan purchased the Shanghai Longmao Spinning Mill, which had been closed for auction, and renamed it Rende Spinning Factory, and put it back into production using a complete set of textile machines produced by Dalong.

The success of Su Lun and Rende Spinning Mill reassured other textile manufacturers and began to purchase complete sets of textile machines from Dalong Machine Factory. Shanghai's Yong'an Spinning Mill and Hongzhang Spinning Factory, and Jiangyin's Utilization Textile Factory have successively adopted Dalong's complete sets of textile machines. In addition, the Yan father and son also invested in some textile factories such as Changzhou Minfeng Spinning Factory, Zhengzhou Lufeng Spinning Factory and Jiangyin Tongren Woolen Textile Factory, becoming shareholders of these factories, and these factories also tried to buy Dalong's textile machines. Da Long also strives to provide these factories with a one-stop service from supply, installation, commissioning to maintenance.
Yan Yutang, who had a great family, was kidnapped twice in October 1928 and May 1932, but he did not die.
"Declaration" 1932-05-05 report [Yan Yutang was kidnapped]
The previous time, Yan Yutang was kidnapped in a rickshaw on Huade Road, and Yan was injured in his left foot during the breakaway, and his charter driver was also shot and injured by bandits, which was not a big problem. But somehow the kidnapping attempted.
The last time, at about 8:30 a.m. on May 4, 1932, Yan Yutang was as usual
Driving the self-prepared no. 8967 car, starting from home (No. 1 pingliang Road, Hudong), going to the Guangyu Business Company at No. 58 Jiangxi Road, arriving at the no. 58 gate, stopping abruptly, solemnly lifting the foot off the car, suddenly three thugs, jumping out from the side of the road, holding a murder weapon in their hands, two bandits supporting the serious return to the carriage, opening the door of one bandit, boarding the driver's seat, threatening the driver with a pistol, Gao A, driving to the south, and at the ai to the ai to the other side, the bandit pushed Gao from the car and then turned his wheel to the west to stop the dust, Afterwards, the coachman reported that the arrest house was arrested, and there was no eyebrow to speak of for a while. The bandits will kidnap Yan and extort 500,000 yuan.
In this case, under the supervision of the Ministry of Works, the general patrol room was commanded by Lu Liankui, the chief inspector of Hua, to investigate and arrest the kidnappers in the whole city. A month after the incident, Inspector Lu finally learned of the secret bodyguard, and immediately sent Inspector Hua Liu Shaokui, Detective Feng Zhiming, Wang Chengying, Zhou Honglin, and others to Room 337 of the New World Hotel on Tibet Road, where they arrested and brought to justice five suspects, including Zhenjiang ren Wang Jian, Yong ren Kong Aliu, Jiangbei Chen Huixing, Dong Xiaosi, and Pudong ye Xianglian.
After interrogation, the suspect Wang Jian confessed to the location where the meat ticket was hidden. Inspector Lu and others immediately, in coordination with the Chinese and Western agents of the French Capture House, rushed to no. 72 Pushi Road (Changle Road, Chongqing Middle Road) in the French Concession to rescue Yan Yutang, and the kidnappers who guarded the meat ticket had already heard the wind and fled, and only confined Yan Yutang to the confinement room, where the agents were about to rescue Yan Yutang, and seized three box guns and one hundred and sixty-three bullets, one pistol and thirty-one bullets and one gas pistol in the house. It is reported that Yan Yutang "operated the Guangyu Business Company, the manager of the Zhabei Long Iron Factory and the Suzhou Suren Textile Factory, so Yan Shi had three positions, but because of his humble birth, self-esteem, self-esteem, life enthusiasm for social welfare, running three compulsory schools, it is reported that there is only a career, there is no savings, every morning to the company to do things, single-handedly in and out, do not hire a bodyguard."
The Declaration was reported on 1932-05-05
Yan Yutang was kidnapped twice, and both of them turned the danger into a disaster, which was a result of cause and effect, and the fate of The Great Blessing day.
Yan Yutang's cotton-iron joint venture developed to its peak before the War of Resistance Against Japanese Aggression. In 1937, the total capital of Dalong was 500,000 yuan, more than 500 mother machines for various jobs, more than 1,300 workers, and more than 200,000 yuan in net profit. Shanghai Hongzhang Spinning Factory commented: "China's first imitation of textile machines, its achievements in the original SuLun factory site, the largest scale, now only Dalong machine manufacturers." ”
After the Japanese army occupied Shanghai, the original Dalong Factory was occupied, renamed the Inner and Outer Iron Works, and turned into a Military Factory of the Japanese Army. Yan Yutang used the machinery and equipment he had hidden, and set up the Taili Machine Factory in the name of the American businessman Taili on Zhu'an Bang Road on Jiangsu Road until the victory of the War of Resistance. After the victory of the War of Resistance Against Japanese Aggression, the Internal and External Iron Works (formerly the Dalong Factory) were confiscated by the Ministry of Economy of the Nationalist Government as enemy property and renamed Shanghai Machine Factory No. 1.
In September 1947, the Yan family redeemed the original Dalong Factory with 600 gold bars. On the eve of liberation, Yan Yutang and others left Shanghai for Hong Kong, and then transferred to Taiwan to open factories and operate. In 1958, Yan was stranded in Taiwan on his way back to the mainland from Brazil, and died of a heart attack in Taipei on October 18. His son Yan Qingxiang stayed behind at the Shanghai Dalong Factory.
1980s, Da long machine factory
Subsequent:
In 1949, while mainly producing cotton spinning machines, The two factories of Dalong and Taili began to manufacture marine thrust shafts, train wheels, metal cutting machine tools, air hammers and other equipment.
In 1954, Dalong Factory and Taili Factory realized public-private partnership, renamed as public-private Dalong Machine Factory, and set up one factory (formerly Dalong Factory) and two factories (formerLyili Factory). With the development of the national petroleum industry, products began to produce petroleum machinery parts. In the same year, a high-strength alloy steel chain was developed.
In 1955, the establishment of the first and second factories was abolished, and 50 small factories such as the Dachang Electric Welding Factory were merged, and a new wrought iron workshop was built, and the heat treatment and casting steel workshop was expanded.
In 1958, Dalong Factory developed into a large-scale backbone enterprise capable of producing complete sets of smelting, forging, petroleum and fertilizer equipment. The first Y-8-3 large-scale mud pump, winch and the first 5-ton forging manipulator in China were produced on trial.
In 1959, the first set of large reciprocating high-pressure piston pumps in China was successfully produced. In 1961, in cooperation with the Institute of Geophysics of the Chinese Academy of Sciences and other 4 units, the first synthetic diamond ultra-high pressure equipment and the first 600-ton non-ferrous metal extruder in China were made.
After 1965, according to the needs of the development of the petrochemical industry, more than 50 kinds of equipment such as ammonia freezers and large carbon dioxide compressors were produced. In 1976, a complete set of hydraulic system devices was successfully developed for the first domestic "Yunshi" large passenger aircraft. Since 1980, it has successively developed 4000 grams of injection molding machines, oilfield surface pumps, water injection pumps, hot recovery boiler feed pumps and various types of ultra-high pressure vessel static pressing equipment.
In 1981, the first set of 135/8-inch diameter, 350 atmosphere offshore oil semi-submersible drilling equipment was produced in China. In 1986, the first 300,000-kilowatt nuclear power plant in China was produced as a supercharging pump, and in the same year, the first large-scale mortar pump of the ash removal system of the 300,000-kilowatt thermal power plant in China was produced on trial.
