Quality & Factory Network
We only work with manufacturers we have audited in person. Here is how we keep quality under control from sampling to shipment.
Our quality process
Step 1
Factory audit before onboarding
We visit every partner factory on site and review production equipment, quality system, test capability and export experience before we work with it.
Step 2
Incoming material control
Aluminium profiles, tubes, rods and seals are checked against specification. Material certificates are available for hydraulic cylinders on request.
Step 3
100% function & leak testing
Pneumatic cylinders are leak and function tested; hydraulic cylinders are pressure tested before shipment.
Step 4
Pre-shipment inspection (optional)
We can arrange an independent third-party inspection (e.g. SGS, Bureau Veritas, QIMA) with a photo and measurement report before you release the balance payment.
