FAQ:
1. Are you a manufacturer or a trading company?
We are a professional manufacturer with over 15 years of experience in designing and producing vehicle machinery parts for both domestic and international markets.
2. How can I get some samples?
If you need, we are happy to provide free samples, but new clients will be responsible for courier costs, which can be deducted from the payment for a formal order.
3. Can you make casting according to our drawing?
Yes, we can produce castings based on your drawings, whether 2D or 3D CAD models. If a 3D model is available, it can significantly speed up the tooling development process. However, even without 3D models, we can still produce approved samples based on 2D drawings.
4. Can you make casting based on our samples?
Yes, we can take measurements from your samples to create drawings for tooling production.
5. What quality control devices do you have in-house?
We have a spectrometer to monitor chemical properties, a tensile testing machine to control mechanical properties, and ultrasonic testing (UT) as a non-destructive testing method to check for internal defects in castings.
