Core Production Processes of Pleated Air Filters
Core Production Processes of Pleated Air Filters
1. Material Selection
Filter Media:Common materials include synthetic fibers (e.g., polyester, polypropylene), glass fiber, or natural fibers (e.g., cotton).
Performance characteristics:Efficiency: Rated by standards like MERV (Minimum Efficiency Reporting Value) for HVAC or ISO 16890 for general ventilation.
Dust Holding Capacity: Determines service life and resistance to clogging.
Compatibility: Resistance to moisture, chemicals, or high temperatures (e.g., heat-resistant glass fiber for industrial use).
Structural Components:Pleat Supports: Metal or plastic frames, cardboard, or non-woven fabric to maintain pleat shape and structural integrity.
Sealants: Adhesives (e.g., polyurethane,hot-melt glue) to bond media to frames and prevent air leakage.

2. Manufacturing Techniques
Pleating Process:Machinery: Automated pleating machines fold the filter media into uniform pleats, with adjustable pleat depth and spacing (e.g., 8–50 mm pleat heights).
Precision Control: Laser sensors or vision systems ensure consistent pleat alignment and spacing.
Frame Assembly:Insertion: Pleated media is inserted into pre-fabricated frames (metal, plastic, or composite) using mechanical presses or adhesive bonding.
Edge Sealing: Hot-melt glue or ultrasonic welding seals the media-frame interface to prevent bypass airflow.
