Q: Are you manufacturer?
A: Yes. We are manufacturer. We have our own technical team. Welcome to visit us.
Q: What payment terms do you accept?
A: We are flexible on payment terms, please contact us for details!
Q: What info you need before you make the proposal?
A: The pipe diameter and thickness range which you need or the profile drawings material information, your special requirements and speed of the machine.
Q: How do you do QA?
A: We have special team do strict QA, this is our strengths:
(1)Every gear box will be tested for 8 hours with oil inside to guarantee there is no leak.
(2)Every shaft will be inspected for the centering jumpiness.
(3)Every roller will be checked to make sure it is in the range of tolerance critical parts will be inspected for all dimensions.
