Quality begins
with the material.

From laboratory evaluation to dimensional inspection, define what needs to be checked — and how — before production.

From the material up

Behind every wheel,
a material decision.

Polyurethane selection starts with the working conditions. Our laboratory images show the equipment and preparation behind material evaluation.

Actual roller face-width measurement. Record your required dimensions and units.

Project-specific inspection

The checks
your part needs.

Mark the critical dimensions, reference surfaces and tolerances on your drawing. Hardness, visual review and any additional tests belong in the agreed inspection plan.

  • Critical dimensions & agreed tolerances
  • Hardness requirement & test method
  • Sample or first-piece review, where required
  • Batch records & packing identification
