Wear Plates

Nov 12,2025

What it is:    
precision sliding and sacrificial surfaces that guide movement and absorb wear between mating mold parts. 

Typical applications:    
long slides, high-contact guideways in automotive, packaging, electronics and medical molds. 

What it solves:    
reduces friction, prevents fretting and misalignment, extends service intervals and protects more expensive mold components. 

Common materials: 
hardened alloy steel, bronze/copper-graphite composites (self-lubricating), nitride or plated finishes. 

Common issues & maintenance:    
loss of lubrication, groove wear, and mounting loosening — inspect clearances and replace worn plates on schedule. 

Selection tips:    
choose copper-graphite for self-lubrication and minimal maintenance, hardened steel for high-tonnage/abrasive resins, and always match ground tolerances to the mold design.
