Before we talk

Do you manufacture to customer drawings?

Yes. Steel castings, machined components, sheet metal parts and welded assemblies are evaluated against the customer’s drawings and technical requirements.

Which processes are in-house?

Casting, heat treatment, machining, sheet metal fabrication and welding are in-house. Galvanizing and electrophoretic coating are arranged through external suppliers when required.

Can you support PPAP and inspection documents?

We can support PPAP and inspection documentation. The submission level, tests, sampling and acceptance requirements should be agreed for the specific project.

What should I send for a technical discussion?

Please include the current drawing revision, material specification, estimated quantities, critical quality requirements and required surface treatment. Add relevant 3D files or sample information if available.

Do you also review ductile iron enquiries?

Yes. Ductile iron enquiries are reviewed separately against the drawing, material specification, quantity and inspection requirements. Acceptance is confirmed for each project.
