Materials and standards

Tolerance ±0.01 mm (down to ±0.005 mm on request); surface Ra 0.4-1.6 µm; equipment: CNC lathes, 3/4/5-axis machining centres, CMM; documentation: material cert, first-article report, inspection plan. All wetted parts are traceable to EN 10204 3.1 mill certificates, and each valve is pressure-tested before packing.

Frequently asked questions

What CAD formats do you accept?
STEP, IGES, X_T, DWG and PDF drawings. We return a DFM review before cutting metal.

How is quality verified?
Every batch is checked on a CMM against the drawing, with a first-article inspection report for new parts and sampling plans for repeat orders.
