Q

Barrel wear

A

This problem is a typical manifestation of barrel wear 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 troubleshooting ...

Q

Over-curing

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...

Q

Overflow flash

A

The root cause of flash is that the mold-opening force generated by the cavity internal pressure exceeds the closing force of the clamping system. The logic chain of the solution is: first reduce the cavity pressure peak through process adjustment, then check and repair the clamping system to ens...
