Mold Structure & Design Description

The mold core plate is installed on the core side of the injection mold and serves as a load-bearing and positioning component.
Key design considerations include:

• Accurate plate thickness and flatness to ensure proper mold alignment

• Machined pockets and mounting features for core inserts

• Compatibility with multi-cavity mold layouts

• Structural strength to withstand injection pressure and clamping force

All core plates are designed and machined strictly according to customer drawings and mold assembly requirements.
