Over-molded process parts: This is a set of plastic molds with 2 injections. The mold making process is very complicated. Can you tell what product it is? Solution to injection molding problem 13. Jetting

Causes:

Injection marks (snake patterns) appear on the injection molded parts, which are caused by insufficient plasticization of the plastic by the injection molding machine, or the plastic

When the material is not completely melted, it enters the cavity through the gate and the subsequent molten plastic.

Condition.

Improve methods:

a) Mould

. Increase the diameter of the mold gate

. Change the gate position

. Add obstacles in front of the gate

b) Injection molding machine conditions

. Reduce injection speed

. Stage optimization and adjustment of injection speed (s-F)

. Check/increase the melting temperature of injection molding

. Increase mold temperature

. Increase back pressure

. Use special injection molding machines. If you need this kind of over-molded process parts, please contact our company Gary Gao: qxwmould_co_ltd@163.com
