Testing and Quality

Rubber verified next to the production line in Beijing — hardness, ozone, ageing, tensile, oil resistance and more — with CTI in Shanghai for certified laboratory work.

Testing beside the press

In our facility in Beijing, right next to the production line, we have all the necessary testing equipment to test our products for Shore A hardness, density, ozone, ageing, tensile strength, elongation to fracture, vulcanization and insulation resistivity, oil resistance and Mooney viscosity.

Why the location matters

A test run in a laboratory a week away tells you what went wrong. A test beside the press tells the operator to stop. Keeping the equipment in the building is the difference between scrap measured in parts and scrap measured in shifts.

Certified laboratory work

We also co-operate with the certified laboratory CTI — Centre Testing International Corporation — based in Shanghai, for results that have to come from an accredited third party.

Production standards

Development runs through our R&D centre in Shanghai and into ISO/TS certified production facilities in Beijing, Shanghai and Wuhan. On programme parts we run PPAP to ISO/TS 16949 or VDA.

What we ask you to specify

Compound family and Shore A hardness on the drawing, the service conditions the part sees, and which PPAP standard applies. Everything else we can propose.

The nine test methods

Shore A hardnessCatches a mis-weighed or wrongly cured batch, and fixes pedal feel.
DensityA fast check that the compound leaving the mixer is the one specified.
Ozone resistancePredicts cracking on parts that live outdoors, such as motorcycle rubber.
AgeingAccelerated ageing: what the part looks like in years, not weeks.
Tensile strengthHow much load the part takes before it tears.
Elongation to fractureHow far it stretches before it fails — the number that matters on boots and gators.
Vulcanization and insulation resistivityConfirms the cure state and the electrical behaviour of the compound.
Oil resistanceRules EPDM in or out where the part sees fuel or oil mist.
Mooney viscosityProcess control: whether the compound will flow the same way tomorrow.

Questions buyers ask

Do you have your own laboratory?

We have the testing equipment in the Beijing facility, next to the production line. For certified results we co-operate with CTI, Centre Testing International Corporation, in Shanghai.

Are your plants certified?

Our production facilities in Beijing, Shanghai and Wuhan are ISO/TS certified. Certificate numbers and current validity are confirmed on request.

Can I get test data with the parts?

Yes — say so at the quotation stage so the right tests are planned into the run rather than added afterwards.

Ready when you are

One email starts it: the part, the volume, and a drawing or a photograph of the sample. Everything else we can work out.
