Material assurance
Three rules we hold to
1Qualification on receiptMaterial is inspected before any machining begins.
2Production-equivalent gradesMachined prototypes use the same plastics and alloys as the real product.
3Special grades on requestFor example PA + carbon fibre, quoted with the programme.
