Blistering/bubbles

The three major causes of bubbles (moisture, air entrapment, vacuum shrinkage cavities) need to be treated differently: moisture type——sufficient drying; air entrapment type——optimize plasticization and injection parameters; vacuum shrinkage cavity type——strengthen holding pressure feeding. Accur...

Over-curing

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...

Overflow flash

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...
