Send Your Drawing. We’ll Review the Manufacturing Requirements.

Most of our products are custom manufactured according to customer drawings, samples, or technical requirements. Send us your project information and our team will review it for manufacturability, process selection, and quotation.

What You Can Send

2D Drawings

Send your technical drawings with dimensions, tolerances, materials, surface treatments, and other manufacturing requirements. PDF, DWG, DXF, and other common drawing formats are supported.

3D Files

STEP, STP, IGES, IGS, and other common 3D formats can be used for geometry review, process evaluation, and quotation.

Physical Samples

If drawings are unavailable, sample-based evaluation may be possible depending on the component, structure, and project requirements.

Technical Specifications

You can also provide material, dimensions, tolerances, spring force, hardness, surface finish, application environment, and functional requirements.

Send Your Drawing

What files and information should I send for a quotation?

Please send your 2D drawing, 3D file, sample, or technical specifications together with material, quantity, tolerances, surface finish, and any special application requirements. More complete information helps us evaluate the project and quote more accurately.

Can you help if my drawing is incomplete?

Yes. If some manufacturing details are not yet finalized, you can still send us the available drawing, 3D model, sample, or application requirements. Our team can review the project and discuss materials, tolerances, processes, and manufacturability with you.

How quickly can you provide a quotation?

Quotation time depends on part complexity and the completeness of the technical information provided. Standard projects can usually be evaluated faster when drawings, materials, quantities, tolerances, and finish requirements are clearly specified.
