Quality Control And Testing
Every-step QC and final QC on in-house test equipment
What This Covers
We take pride in our rigorous quality control processes, which include every-step QC and final QC checks to ensure that all goods are of the highest quality before packing. The testing is done on our own equipment, on site, which is why the results come back inside the production schedule rather than after it.

- In-process QCChecks at every step of assembly rather than only at the end of the line.
- Electrical and charging testPD test station for charging behaviour and function.
- Environmental and safety testBall pressure temperature test chamber and horizontal and vertical flammability tester.
- Mechanical abuse testDrop tester, dual drum drop tester, falling ball impact tester, abrasion wear test machine.

Will my model be certified?
Certification scope is agreed per project, because it depends on the model and the destination market. Ask for the current certificate list for the specific model you are quoting.
Can I inspect before shipment?
Yes. We warmly welcome you to visit us anytime, and third party inspection can be arranged at either site.
