1. Precise design required size of the filter cloth for filter bag parts, the filter cloth will larger than the actual amount design size, to leave a spare for weaving.
2. To choose the right filter bag accessories, specifications and check its quality. The filter bag accessories should match the filter bag quality requirements.
3. We make the filter bag line drawing, cutting, sewing on automatic production line. When the filter bag need manual processing, we will open it on the operation platform, and with certain pulling force to keep it is flat.
4. We keep the strict processing quality standards, according to design drawings and operation process. Our worker meet the requirements of tooling and clothing shoes and hats, no smoking.
5. We have the responsible for the processing of products, and examines, waste, residue, defective goods in the beginning.

HUADING has now become a comprehensive service provider for collaborative air pollution control, providing systematic solutions for air pollution control.

The company has its own science and innovation research institute and a group of top R&D personnel in the industry. In addition, German imported filter material production line and advanced testing equipment are the cornerstones of the company's high-quality products.

1, Fiber, efficient filtration, reduce emissions and running resistance.

• Filter bag manufacturers select fine fibers to increase the filtering area and reduce the filtering gap of filter materials, thus improving the filtering efficiency of filter materials, reducing the emission concentration and running resistance.
• The filter material is produced by imported equipment, and the performance of the produced filter material is stable.

2. Post-treatment of filter materials guided by customers' working conditions.
According to the change of dust characteristics, the needle felt filter material is treated with different surface or coated with protective layer to meet the needs of customers under different working conditions.

3. The filter bag shall be manufactured in strict accordance with the national standard of GB12625-90 to ensure the qualified rate of products leaving the factory.

• Elastic expansion ring and saddle pad (non-rubber ring) made of the same material filter material are adopted at the bag mouth, so as to avoid the rubber ring aging at high temperature and cause the filter bag to fall off.
• The seam of the bag mouth shall be treated by dislocation to ensure the close joint between the bag mouth and the flower plate and avoid dust leakage from the flower plate hole.
• the needle distance of the filter bag is 25 1, and the filter bag has no drop or float line, and the comprehensive strength of the seam of the filter bag is > 1000N.
