Frequently Asked Questions
Q1: What materials are available for pins and punches?
A: High-speed steel (M2, M42), powder metallurgy steel (ASP30, ASP60, CPM REX 76, CPM REX M4, CPM REX T15), and micro-grain tungsten carbide.
Q2: What surface treatments are available?
A: TiN coating and patented ACN surface treatment, applied to improve wear resistance under cold heading impact conditions.
Q3: Can custom-designed pins and punches be manufactured?
A: Yes, production is based on customer drawings and specifications, including complex profile geometries.
Q4: What is the typical manufacturing tolerance?
A: Tolerances are confirmed per customer drawing requirements at the quotation stage. Please provide your tolerance specification for an accurate quote.
Q5: What material is recommended for high-volume production?
A: Material selection depends on the specific cold heading application and expected tool life. ASP30/ASP60 powder steel and carbide are typically specified for higher-volume production; specific recommendations are provided after reviewing your drawing and production parameters.
