Quality Control
Every-single unit is tested at least twice through-out the manufacturing cycle
The first test is a visual inspection. The operator makes sure that:
- The part is placed in its fixture to ensure proper fitment on the vehicle.
- The welds are completed without any holes or gaps.
- The ends of the pipes are fished to the proper specifications.
The second test is a pressure test. The operator blocks all of the entrances and exits of the part and fills it with compressed air with a pressure equal to five times that of a standard exhaust system. This guarantees the structural integrity of the welds holding the piece together.
With over 10 years of experience, we will constantly enrich our technical and service skills, to win the trust of customers with our enthusiasm and sincerity, achieve win-win in cooperation and seek common development and growth with distinguished customers, suppliers and fellows.
