Inspect whether the quality of the materials used in production meets the technical requirements of the design, strictly control the process of non-conforming products, and ensure the quality of the products.
1.Incoming Quality Control
The quality of the filter paper is related to the efficiency of the filter. The high-quality filter paper can filter more impurities, which protects the engine and prevents engine wear.
2.Filter Paper Folding
Ensure the quality of raw materials, no deformation and damage when subjected to pressure.
3.Punching
Guaranteed filter leak tightness and functional integrity.
4.Seaming Assembly
A series of tests are carried out by special inspectors in accordance with the design drawings to ensure that the finished products meet the design requirements, and the final qualified products enter the market. Ensure high product filtration performance, low pressure loss rate and long life.
5.Testing
