The foundation of high-quality automotive air filters lies in rigorous raw material selection and pre-production inspection. At professional auto filter manufacturing factories, every batch of filter media, rubber sealing materials, PU glue, and metal accessories undergoes comprehensive physical and chemical testing be
Pleating forming is the most core process in air filter production, directly determining the effective filtration area, dust storage capacity, and air intake resistance of the product. Modern filter factories adopt fully automatic CNC pleating machines to replace traditional manual folding, realizing precise digital co
