FAQ

Trust and Verification Questions

How do I know these photos are your own factory?
They are the photographs the factory itself published of its plant its Sinter-HIP furnace its products and its exhibition stand. We have not added stock photography or generated images to make the site look larger.
Do you hold certifications?
Certificate copies and material documentation are supplied on request with an order. We do not display certification claims on this site that we cannot show you. Tell us what your QA or import process requires and we will confirm what can be provided.
Can you supply references from existing customers?
Customer identities are not published without permission. What we can show you are the documented parts on our application example pages including dimensions and hole counts.
What quality checks are made before shipment?
Critical dimensions agreed on the approved drawing are checked before packing. Agreeing which dimensions are critical up front is what makes the check meaningful.
