Main Challenges

The position of the winding reel in the middle of the product has a thin wall thickness and is very dense. EDM processing is very complex, and the mold is very easy to break. There are many defective products and serious material shortage in injection molding. For the wall thickness problem, first, we replaced the product material and used PC + ABS material, which increases the willfulness of the product and is not easy to break; Second mold core material is treated with S136 heat treatment to increase the life of strength die. Second, we make the middle part into replacement inserts, which can not only solve the problems of mold damage and repair caused by improper injection molding operation, but also solve the problem of gas trapping and material shortage of products.
