The production process

Over 75% of production costs are determined at initial design stage. Our experienced staffs will assist with clients about production possibilities and make suggestions of material used.

When an order is released and test runs will be start with Production Part Approval Process (PPAP III), that is addressed to the quality level of raw material, controlling the tolerance and stability during production process.

These test samples will be taken randomly from each stages during production process. The successful test results will be used to maintain production stability. The follow-up mass production will be start once the sample is approved from our client.

We commonly use cold-forging to manufacture stainless steel fasteners and hydraulic fittings. This technique is more efficient in output rate (time saving) and less material consumed. Cold-forging production starts with forming to create blocking, then CNC machining at last.

With manufacturing processes of steel pipes/tubes start with:

  1. Raw material inspection

  2. Cutting

  3. Degreasing

  4. Swaging

  5. Heat treatment

  6. Surface treatment

  7. Cold drawing

  8. Straightening

  9. Eddy current testing

  10. Finished product inspection

  11. Packaging

  12. Delivery
