Service and quality information: 

1. Q: Can you make as per custom drawing?
A: Yes, we can do that.

 

2. Q: If I don’t have drawing, what can you do for me?
A: If you don’t have drawing, but have the sample part, you may send us. We will check if we can make it or not.

 

3. Q: How do you make sure the quality of your products?
A: We will do a series of inspections, such as:
    a. raw material inspection (includes chemical and physical mechanical characters inspection),
    b. machining process dimensional inspection (includes: 1^st pc inspection, self inspection, final inspection),
    c. heat treatment result inspection,
    d. gear tooth inspection (to know the achieved gear quality level),
    e. magnetic particle inspection (to know if there’s any cracks in the gear).
    We will provide you the reports 1 set for each batch/ shipment.
