If that fails to correct the problem, you may have to increase the gate size.
A mold that is too cold, a melt that is too cold, and/or a gate that is too small lead to surface delamination (blistering) around the gate.
If that does not solve the problem, increase the gate size.

Edge Gate
This is the most common manual trim gate.
Sprue Gate
The sprue is gated directly into the part.

gate, and is a tapered gate that intersects the
part below the parting line.

MOLD DESIGN RECOMMENDATIONS
Gates
• Many different types of gates can be used, such as fan, tunnel, tab,
and edge gates
Gate thickness should be
50–75% of wall thickness
Avoid gating into thin part region.
