Send Your Drawing

Start With Your Requirements

Send us your 2D drawing, 3D file, sample, technical specifications, or application requirements.

Drawing Review

We Review Your Requirements

We check key dimensions, tolerances, materials, surface treatments, functional requirements, and production quantities.

Engineering Evaluation

We Evaluate Manufacturability

Our engineering team reviews geometry, machining or forming feasibility, process requirements, and potential production risks.

Prototype Development

We Produce Initial Samples

Prototype parts are manufactured for dimensional verification, fit testing, functional evaluation, and customer approval.

Sample Approval

You Confirm the Final Specification

After sample evaluation, confirmed requirements are recorded before production begins.

Mass Production

Controlled and Repeatable Production

Production is carried out according to approved drawings, samples, process parameters, and quality requirements.

Quality Inspection

Inspection Before Release

Critical dimensions, appearance, materials, and specified quality requirements are inspected before shipment.

Delivery

Packed and Ready to Ship

Finished components are packed according to agreed requirements and prepared for domestic or international delivery.

What information do you need to start a custom manufacturing project?

Please send us your 2D drawing, 3D file, sample, material requirements, tolerances, surface finish, quantity, and any special application requirements. The more complete the information, the faster we can review and quote your project.

Can you produce prototypes before mass production?

Yes. We can support prototype development and sample production for dimensional verification, fit testing, functional evaluation, and design confirmation before moving into mass production.

Can you support both small batches and mass production?

Yes. We support prototypes, small-batch production, pilot runs, and repeat mass production. Production planning is adjusted according to your quantity, technical requirements, and delivery needs.
