Weixin technology is a professional key chain manufacturer. It has mature technology and technology for the production of key chain. The following is an example of PVC Key chain production. The production of PVC soft rubber products, no matter proofing or production of large goods, are completed by independent manual mold. Generally, copper and aluminum are used to make molds. Copper mold price slightly higher, but durable, copper mold thermal conductivity is more uniform, so PVC products using copper mold is the best.

    After the completion of the normal mold, the first step is to clean the mold. The cleaning mold has special cleaning water or PVC soft rubber waste cleaning. After cleaning and heat treatment, the mold can be formally put into production. Automatic dispensing machine has been used to replace manual operation in the production of PVC Key chain. However, there are still immature places in the production of the machine. It is difficult to grasp the quality of products in too small places, and the cost is high. If the orders with large quantities and simple product design, it is difficult to use the automatic dispensing glue to produce on-line, There is a small detail that needs to be paid attention to when dropping glue. There is only a line between the color and the color. It is not allowed to apply glue at the same time, otherwise it will lead to color mixing. The baking temperature of PVC soft glue products can be about 80 degrees, too high will easily lead to product deformation.
