Frequently Asked Questions (FAQ)

Q1: Are these core inserts standard sizes?
A: No. All parts are custom-manufactured based on customer drawings and specifications.

Q2: What is the benefit of nitriding for mold core inserts?
A: Nitriding increases surface hardness and wear resistance while maintaining internal toughness, extending mold service life.

Q3: Can grinding and nitriding be combined in one process?
A: Yes. Grinding ensures dimensional accuracy, and nitriding is applied afterward under controlled conditions.

Q4: Which industries typically use these inserts?
A: Packaging molds, medical packaging molds, and other precision plastic injection molding applications.
