We do this by:

  • Monitoring all incoming raw materials, ensuring they comply with both customer and industry specifications.
  • Perform in-process stock-shape dimensional and ultrasound testing/inspections.
  • Dimensional and visual inspection after secondary processing such as annealing and semi-finishing.
  • Warehouse inventory inspection occurs upon receipt of materials and prior to packaging/dispatch.

Protecting Our Environment

Polymer recyclability and diverting our products away from landfills is essential to us creating a closed-loop process. All polymer manufacturing & finishing waste is placed through our recycling program. This processes our cast nylon waste (solids and swarf) into both extrusion and moulding grade pellets.

All metal machining waste is recycled into secondary raw material for the smelting of new metals.
