Mold Structure & Design Description

In injection mold assemblies, conical core pins are typically positioned to form internal or tapered plastic features while supporting smooth part release.

Key design considerations include:

• Conical angle accuracy for consistent part geometry

• Surface finish requirements to reduce demolding resistance

• Dimensional matching with cavity inserts and mold plates

• Structural strength to withstand repeated injection cycles

• Compatibility with high-speed, multi-cavity mold layouts

Each core pin is produced strictly according to customer-provided drawings and mold design requirements.
