With the continuous growth of the global automotive aftermarket's demand for high-quality filters, Dongsen Auto Parts Co., Ltd. has been increasing its technological investment and strictly standardizing the production process of air filters to ensure that every product leaving the factory has stable and reliable filtration performance, in order to meet the high standards of quality requirements of domestic and foreign customers.
The company has always adhered to the principle of "Good filter elements start with good materials". All raw materials for air filters come from the high-quality supply chain in the industry, including:
Imported and domestic high-grade wood pulp paper, composite filter paper
Environmentally friendly PU sealing material
High-durability non-woven fabric, metal support net
High-temperature stable adhesives and sealing materials
All materials entering the factory must pass multiple tests such as quantitative measurement, thickness, hardness, air permeability and filtration efficiency to ensure they meet the enterprise's quality control standards.
Automated production equipment ensures precise molding
In the production process, the company employs multiple automated devices to achieve batch and high-precision manufacturing:
Filter paper cutting
The automatic cutting machine ensures that the filter paper has precise dimensions and smooth cuts, avoiding burrs and damage.
Origami shaping
Advanced origami equipment can achieve uniform folding, ensuring consistent folding numbers and spacing, thus providing the filter paper with a larger effective filtration area.
Metal mesh processing
For the models that require the installation of support nets, galvanized steel nets are processed by automatic forming equipment to enhance the structural strength of the filter element.
Strict sealing process ensures product stability
The sealing quality of the air filter determines its filtering effect. Etsen adopts an automatic glue injection system to strictly control the amount of glue, injection accuracy and curing time.
No glue leakage or overflow
The seal is stable and does not deform
It does not fall off in high-temperature environments
Ensure that the product remains stable and safe under all working conditions.
Standardized packaging and logistics services ensure safe delivery
The company offers standardized packaging and OEM customized packaging services, and adopts an anti-pressure protection design to reduce the risk of damage during transportation. Each box of products is marked with model identification and batch information, which is convenient for storage and traceability management.
