For product teams

Bring the right questions to the first sample.

  • FitWhat webbing, leather, zipper tape or neighbouring component must the part accept?
  • FunctionDoes it lock, adjust, swivel, attach, protect or simply add a visual detail?
  • LoadWhat pull, movement or packed-bag condition should be discussed before approval?
  • FinishWhich plating colour, custom colour or surface reference should the sample follow?
  • QuantityWhat is the expected order range and is 500 pcs an appropriate starting point?

Before you specify

Choose the material and finish with the part in view.

A sculpted closure, a small logo plate and a strap ring face different design constraints. Compare manufacturing route, surface, attachment and intended use before finalising a material.
