1, plastic injection molding electronics processing

Up to 20% of recycled material can be mixed with new material. The amount of recycled material depends on the end use of the product. Misuse of recycled materials can cause injection molding failures, not only because the recycled components are excessive, but more because the materials are reprocessed many times. The quality of the recovered material will decline more once it is recovered.


2, plastic injection molding electronics machine selection

UPVC has a large melt viscosity and is easily decomposed. The decomposition product has a corrosive effect on iron. Its plastic injection molding must use special plasticizing components and a temperature control system.


3, plastic injection molding electronics design

The length of the runner must be short, and the diameter must be large in order to reduce the pressure loss and hold the pressure to the mold cavity. The mold is made of stainless steel. The content of chromium is at least 13%, preferably 16%. The Rockwell hardness is at least 55. The hard steel mold can be chrome-plated to form a protective effect.


4, melt temperature and injection speed

Can be measured by the air-ejection method, ranging from 185-205°C.The rate of fire is slow, otherwise excessive shearing will degrade the material and use multi-stage injection mold filling speed.
