Quality Assurance:
1. Processing of braid
Our braid products are done strickly followed our internal flow of processing, the products are in accordance with technical requirements such as: no less wire, broken wire, selfless head leakage, uniform appearance, close strict etc. for each process there’s a strict Quality Test Procedure.
2. Number of bellows:
For the same size of exhaust pipes, the number of our bellows has 30% more than that of our competitors.
The increase in number of bellows would increase the damping effect and noise reduction.
Under same operating conditions our products would greatly increase the product lifetime, reduce the use cost of owner.
3. Welding procedure
welding process has strict production process and operation guide book
welding consistent, smooth, neat
welding products without sand holes, porosity ,ensure that no leakage
