• High-volume multi-cavity moulds requiring stable ejection

Applications are limited to industrial packaging and medical-related injection molding.

Mold Structure & Design Description

Ejector pins and mould inserts play a critical role in part release and mould longevity. When manufactured from Stavax stainless steel, these components provide enhanced corrosion resistance while maintaining dimensional stability.

Key design considerations include:

• Ejector pin straightness and surface finish

• Fit and clearance within ejector systems

• Insert alignment with cavity and core structures

• Heat treatment balance between hardness and toughness

• Interchangeability for maintenance and replacement

Each component is engineered to integrate seamlessly into the customer’s mould structure.
