02 / MANUFACTURING

Connected processes.
A clearer path to your part.

Bring the material, casting, heat treatment and finishing requirements together at the technical review. Then agree the manufacturing route for your component.

Laser cutting
CORE PROCESSES IN-HOUSELaser cutting
01Casting

Shell mould casting for steel and ductile iron components. Material specifications, casting geometry and inspection requirements are reviewed before tooling.

02Heat treatment

Normalizing, quenching and tempering to the agreed material condition. Treatment requirements and mechanical properties follow the approved technical specification.

03Machining

CNC machining of cast blanks and drawing-defined components. Datums, fits, critical dimensions and inspection requirements are established during the technical review.

Machining
04Fabrication & welding

Cutting, forming and welding for sheet metal parts, brackets and assemblies. The scope of fabrication and assembly is agreed against the drawing.

Fabrication & welding
05Surface treatment

Galvanizing and electrophoretic coating are arranged through external suppliers when specified. Coating scope, acceptance criteria and supplier controls are confirmed for the project.

03 / QUALITY

The drawing sets
the standard.

Material verification, dimensional inspection and agreed documentation connect the technical requirements to the delivered component.

Before we talk

Do you manufacture to customer drawings?

Yes. Steel and ductile iron 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.
