MOLD DESIGN RECOMMENDATIONS
Gates
• Many different types of gates can be used such as pin, fan, tunnel, tab and edge gates.
Gate type should be selected based on location and part geometry
Gate diameters equivalent to 50% of the average wall thickness are recommended

Edge Gate
This is the most common manual trim gate.
Sprue Gate
The sprue is gated directly into the part.
Tunnel Gate
A tunnel gate is the most common automatic
gate, and is a tapered gate that intersects the
part below the parting line.
