Q

Uneven release agent coating

A

This problem is a typical manifestation of uneven release agent coating in transfer molding; the core of the solution lies in the rational design of the runner and gate system, the effective transmission of transfer pressure, and the uniform control of mold temperature. It is recommended to start...

Q

Product weld lines

A

Weld lines cannot be completely eliminated but can be greatly reduced. The core strategy is to let the two melt streams converge under conditions of high temperature and low gas resistance——raise the mold temperature to slow the front cooling, improve venting to eliminate air cushion blockage, op...

Q

Product embrittlement

A

The essence of embrittlement is that the material's toughness reserve declines to the point of being unable to meet use requirements. The control key is the 'three temperatures'——processing temperature (avoid excessive degradation), drying temperature (avoid too low leaving residual moisture and ...
