Guangdong Hongtu: Integrated die castings have just been trial production off the production line, and the pass rate target is 90%

Set micro network news, recently, Guangdong Hongtu said in an institutional survey that the integrated die casting has just been trial production off the line, the statistical yield still needs to depend on the capacity climbing situation, until the equipment and process are stable before tracking, the goal is to reach 90% of the pass rate, the production beat of 120s / piece.

With the development of new energy vehicles, its production and marketing proportion will gradually increase, body lightweight will be the only way for future development, and with the promotion and popularization of the power exchange model, the standardization of battery shell specifications is worth looking forward to, it is expected that the future new energy vehicles in the field of die-casting aluminum alloy parts Market space is very large, Guangdong Hongtu business planning is the main lightweight, integrated market, and strive to occupy the commanding heights.

Guangdong Hongtu in the new energy vehicle business, from the previous follower gradually changed to the leader, in recent years and customers have more technical reserves, has successfully developed such as shock towers, front and rear longitudinal beams, battery housing and other new energy vehicle products, the future will be combined with the customer's development direction in the integration of the front cabin assembly, integrated rear floor assembly and integrated battery tray and other key core lightweight components layout and force. At present, we are actively engaging with relevant customers in the simultaneous development of integrated die casting products.

It is understood that the die casting industry, especially the industry facing the integrated die casting field, is capital-intensive and technology-intensive, and has a high entry threshold.

Integrated structural parts production and manufacturing has a high technical barriers, structural parts are mainly divided into chassis and body two categories, integrated body and chassis on the performance requirements of high-strength and high-toughness aluminum alloy materials are very high, Guangdong Hongtu has begun to do related technical reserves a few years ago, has developed three kinds of high-strength and high-toughness die-casting aluminum alloy materials with independent intellectual property rights, can meet the mechanical performance requirements of structural parts without heat treatment. In addition, due to the great influence of heat-free treatment materials on the subsequent processing technology, Guangdong Hongtu also supports the corresponding connection technology for the produced castings, and has independently developed technologies such as riveting, motor jointing and articulation, and the related technologies are at the domestic leading and international advanced level. In terms of material forming process (die casting manufacturing process), with years of technology accumulation and precipitation, Guangdong Hongtu has an independent experience database, such as high vacuum die casting, mold temperature control and other core technologies, and has obtained the most independent patents in China. In terms of equipment, the front-end design stage integrates the company's many years of experience, including the front-end design of production equipment in material development, mold design and manufacturing, process development and equipment control points according to product characteristics.

At present, Guangdong Hongtu has 2-3 mold partners, Guangzhou cavity is one of them, in the super large mold has an advantage; Guangdong Hongtu in 2019 to set up a mold company, mainly to do medium and large molds, hope to develop their own core production process technology in their own hands, master Know-How.

In terms of competition, Guangdong Hongtu said that although the current die casting industry is large and scattered, the counterparts in Guangdong are basically healthy competition, both competition and cooperation, and peers work together to make the industry bigger, grow together, promote each other, and win-win results.
