Air Filter Workshop

Filter media is cut and pleated, reinforced with mesh and bonded into shape, subjected to airtightness testing and verification, and—upon passing—packaged and stored in the warehouse.

Air Pre-filter Workshop

Raw materials are cut and pleated, fitted with protective mesh frames, and sealed with end caps; after passing quality inspection, the finished products are packaged.

Oil Filter Workshop

Filter paper folding and winding; housing stamping and welding; adhesive injection, assembly, and sealing; pressure testing and packaging of the finished product.

Injection Molding Workshop

Raw material drying and plasticization; mold injection molding; cooling, demolding, and trimming; inspection, sorting, and warehousing.

Diesel Filter Workshop

Filter paper folding and curing; housing assembly and sealing; pressure resistance and airtightness testing; final inspection, packaging, and warehousing.
