The route

A clear path from enquiry to dispatch.

No black box. Every project starts with drawing review and ends with inspection against the approved requirements.

01

Send the RFQ

Drawing, 3D model, material, hardness, critical tolerances, quantity and target date.

02

Drawing & DFM review

We check geometry, tolerance stack-up, process feasibility and any missing specification.

03

Quotation

Scope, material, inspection, packaging, lead time and commercial terms confirmed in writing.

04

Sample / first article

Prototype or sample produced and inspected against the drawing before batch release.

05

Production

Machining, heat treatment coordination, finishing and in-process checks under the approved plan.

06

Final inspection & packing

Critical dimensions verified, documentation agreed, parts protected for export transit.

What to send

A complete drawing package gets a faster, better quote.

If a requirement is not on the drawing, say it explicitly in the enquiry. The same applies to inspection reports, material certificates and packaging requirements.

01
Geometry

2D drawing and/or 3D model in PDF, STEP, IGES, DWG or DXF. ZIP archives are accepted.

02
Material & treatment

Grade, hardness, heat treatment, coating or surface finish where specified.

03
Critical requirements

Tolerances, fit, edge condition, inspection method and any documentation required.

04
Commercial context

Prototype or production, initial quantity, repeat volume and target delivery date.

Confidentiality

Your drawings stay your drawings.

We can review and sign a non-disclosure agreement before you share models or drawings. Customer files and project details are not used for public promotion without permission.

Materials

Material choices for wear, hardness and corrosion.

Send the working conditions as well as the drawing. The right grade depends on impact, abrasion, corrosion and the production route.

Material familyTypical application
Tungsten carbideWear-resistant punches, dies, bushings and inserts
High-speed steelPunches, cutting edges and high-hardness tooling
Tool steelH13, Cr12MoV and application-specific tooling grades
Stainless steelCorrosion-resistant mechanical and mold components
AluminumLightweight fixtures, housings and machine parts
As specifiedCustomer-approved grades with mill certificates on request
Request for quotation

Have a drawing? Let’s engineer the part.

Send the geometry, material and quantities. We will review manufacturability, confirm the critical features and come back with a practical quotation path.
