Precision CNC Knife Pleating Machine for Air Filter Media

Shop precision CNC knife pleating machine for air filter paper. Features 12-30mm adjustable pleat height, 400mm working width & PLC touch control.

This high-precision CNC Knife Pleating Machine is specifically engineered for folding cellulose air filter paper, synthetic non-woven materials, and flexible filtration media. By utilizing reciprocating upper and lower folding knives, it ensures crisp, uniform, and permanent pleats without cracking the fiber structures of the media.

With its compact footprint and stable automatic operation, this machine is highly favored by global manufacturers specializing in small-to-medium-scale filter assembly. It serves as an essential tool for creating consistent pleat pitch and exact pleat counts required by high-performance cleanroom and automotive filtration standards.

Key Features & Mechanical Advantages

1. Precision CNC Knife Pleating Mechanism

The pleating knife movement is managed by a micro-step control system, allowing the blade to press and mark the filter paper with extreme consistency. This ensures that every fold remains perfectly straight and parallel, preventing common defects like pleat tilting or unequal spacing.

2. Digital Pleat Height & Pitch Adjustment

Instead of relying on tedious manual gear changes, operators can adjust the pleat height within the 12–30 mm range and modify the pleat spacing directly on the touchscreen HMI. This digital precision drastically reduces machine idle time during product specification changeovers.

3. Stable Pneumatic Tension & Feeding

Equipped with a pneumatic feeding system operating at 0.6 MPa, the machine maintains constant tension on the filter paper roll. This prevents the material from slipping or tearing during high-speed folding cycles, ensuring uniform density in the finished pleated packs.

4. Compact and Durable Construction

Constructed with a heavy-duty steel frame, the machine provides vibration-free performance. Its compact 400 mm working width makes it highly suitable for workshops with limited space, cleanroom environments, or dedicated auxiliary production lines.

Applications & Industrial Uses

This specialized CNC knife pleater is widely utilized in the production of high-quality pleated filter inserts, including:

  • Automotive Cabin Air Filters: Folding synthetic and carbon-loaded media for passenger car climate control.
  • Medical & Cleanroom Filtration: Creating mini-pleat elements for HEPA and high-efficiency particulate air purification.
  • HVAC Panel Filters: Small-scale industrial dust collectors, commercial air inlets, and specialized cartridge filters.

Frequently Asked Questions

This machine is optimized for standard cellulose air filter paper, synthetic non-woven fabrics, and lighter-weight flexible filter media. For continuous, high-volume production, please view our Automatic Zig-Zag Rotary Air Filter Paper Pleating Machine. For extremely abrasive heavy fiberglass rolls, please consult our engineering team for heavy-duty blade pleating options.

The pleat height can be set and adjusted digitally via the touchscreen HMI control panel. Minimal mechanical fine-tuning of the knife stroke on the front assembly may be performed to achieve micro-level tolerances.

We prepare and test every machine carefully. Please contact our sales team with your specific voltage requirements and target delivery port, and we will provide a detailed shipping schedule and formal B2B quotation.
