Uneven mold temperature

This problem is a typical manifestation of uneven mold temperature 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 trou...

Product weld lines

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...

Product embrittlement

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 ...

Product warpage deformation

Warpage is the macroscopic bending caused by inconsistent shrinkage of various parts of the product. The solution idea is: achieve uniform cooling of all parts during the cooling stage (cooling water channel optimization), adopt symmetrical layout and isotropic design in structural design (wall t...
