QUALITY
Quality & Inspection
Material verification, process planning, dimensional inspection and agreed testing for steel components.
Quality starts with the drawing.
Our approach brings engineering review, process planning and inspection into the manufacturing route.
CAD/CAM and casting simulation support tooling, fixture and process development. Material, dimensional and testing requirements are reviewed with the customer before production.
