Understanding Tolerances in Rubber Extrusion Manufacturing
Corinne Salt
Share
Unlike rigid materials, rubber behaves differently during production and use. Understanding realistic tolerances is key to successful extrusion design.
Why Rubber Tolerances Matter
Factors affecting tolerances include:
Material shrinkage
Profile complexity
Cure method
Production volume
Overly tight tolerances can increase costs without improving performance.
Working to Industry Standards
Experienced manufacturers work to agreed tolerance bands rather than unrealistic nominal dimensions.
Seal Extrusions advises customers early in the design process to ensure expectations align with achievable manufacturing outcomes.
