OUR RULE

Check before we build, check before we ship

01

Drawing review before quote

Engineers check structure, pitch, edge, material and the drive interface before we quote.

02

Signed drawing

Production starts from the drawing you approve and sign. It sets the dimensions we inspect against.

03

First article first

A trial piece or first article is checked and confirmed before mass production.

MATERIAL VERIFICATION

Material you can verify

We draw our own stainless wire and round bar. Checks start before the first bend.

01

Chemical composition

A spectral analyzer confirms the stainless grade of each incoming batch of wire and bar.

02

Hardness

A hardness tester checks incoming material before it goes to drawing or forming.

03

Wire diameter

Calipers confirm wire and rod diameters against the specification.

04

Traceable records

Each order is recorded from material to finished belt, so repeat orders are built the same way.

FAQ

Questions about quality control

Q01

Do you inspect every belt?

Yes. Every formal belt gets a final inspection against the approved drawing before packing.

Q02

Can a third party inspect our order?

Yes. Third-party inspection and factory audits are supported on request. Tell us the inspection body and scope when you order.

Q03

Do you provide material certificates?

Material and inspection documents are prepared per order. Tell us which documents you need before production.

Q04

Is your ISO 9001 a product certification?

No. ISO 9001:2015 certifies our quality management system. It is not a product or food-contact certification.
