How much does it take for mahogany raw materials to be imported from the furniture to the furniture? How many catties of mahogany furniture can be made from a ton of mahogany raw materials? Xiaobian tells you that a ton of mahogany raw materials can only make a maximum of 600 catties of mahogany furniture from import to furniture, and the remaining 1400 catties are consumed in the production process.
Generally speaking, the loss of moisture after drying of mahogany raw materials is 15%, the average loss of flat saws is 8%, the loss of planing is 8%, the loss of carving molding is 18%, the loss of splitting damage white fat is 20%, and the actual utilization rate of mahogany raw materials is 31%. Therefore, according to the calculation of one ton of mahogany raw materials, it can only be made into about 600 catties of mahogany furniture.
After we understand the calculation method of the yield of mahogany raw materials, today we will take you to see how the rosewood is lost in the production process.
The cutting process of mahogany, including the cutting of large and small materials, the adjustment of straight materials and bent materials, etc., will produce a large amount of wood powder and wood chips, and a lot of mahogany wood will be lost. The amount of loss is 8% of the whole wood in the process of cutting, will remove the part containing white bark, insect eyes, rotten heart, which is the most generated whole piece of waste link, all kinds of mahogany waste is different, but the proportion of waste wood can reach an average of 20%, these wastes can not be used to make mahogany furniture at all.
Mahogany wood is dried several times before it can be used. The loss of moisture after drying is 15%. Good mahogany wood is dried three times before making furniture, and the sheets and squares are dried separately.
The mortise and tenon process in mahogany: tenoning, tenoning, wood cutting adjustment, etc., inevitably produce a batch of sawdust and leftovers. Carved and formed, the mahogany wood loses 18%.
After the mahogany furniture is assembled and painted, it is necessary to scrape and grind, and more than ten kinds of scraping tools are used to scrape and grind in order to make the mahogany furniture smooth. After scraping and grinding, it is also necessary to use sandpaper with different mesh numbers to scrub in order to make the mahogany furniture delicate.
After painting, the mahogany furniture is completely done, and finally it needs to be repeatedly dried for 20-25 days before it can be faced to consumers, which will remove some moisture and lose weight.
As can be seen from the above, it is really expensive to make mahogany furniture, and the 31% mentioned above is only a rough estimate, and there are many unforeseen losses in the actual processing and production process, and the yield of mahogany raw materials of different materials is also very different, and different quality requirements will also make the yield of mahogany very different.
