FAQ
-------------------------------------------------------------------------------------------------------------------------------------------------------------------1. What do you do? We are a professional manufacturer with over 15 years' export experience for designing and producing vehicle machinery parts. Focus on saving cost, function approach, production feasibility for your projects.2. How can I get some samples?
If you need, we are glad to offer you samples for free, but the new clients are expected to pay the courier cost, and the charge will be deducted from the payment for formal order.3. Can you make cnc machining according to our drawing? Yes, we can make daccording to your drawing, 2D drawing, or 3D cad model. If the 3D cad model can be supplied, the development of the tooling can be more efficient. But without 3D, based on 2D drawing we can still make the samples properly approved.4. Can you make cnc machining based on our samples? Yes, we can make measurement based on your samples to make drawings for tooling making.5. What's your quality control device in house? We have spectrometer in house to monitor the chemical property, tensile test machine to control the mechanical property and UT Sonic as NDT checking method to control the casting detect under the surface of cnc machining parts
