Q

Product dimensions out of tolerance

A

This problem is a typical manifestation of product dimensions out of tolerance 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 t...

Q

Product warpage deformation

A

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...

Q

Premature curing in the runner

A

The core of curing abnormality is that the rate and degree of the crosslinking reaction deviate from the optimal window. The adjustment idea is the 'three-element method': formulation (precise metering of catalyst/curing agent), temperature (precise control of mold and material temperature), time...
