mould punches

High performance stamping mould punches for round press tool die set

ms mold parts
Self-lubricating cylindrical sleeves made from composite materials (e.g., polymer or bronze-PTFE), designed to provide smooth linear or rotational motion with minimal friction (coefficient 0.04-0.08). Ideal for high-load machinery, they reduce wear, eliminate external lubrication, and extend component life in molds, automation systems, and industrial equipment.
