Semi-Automatic Filter Assembly Lines

Automatic CNC Filter Media Feeding, Folding & Slitting Production Line

Industrial-grade automatic CNC filter media feeding, folding, and longitudinal slitting production line designed for high-precision panel filter manufacturing. Features a 1000 mm working width, adjustable 10–100 mm pleat heights, and multi-blade inline slitting. While our Heavy-Duty Air Filter Pleating Production Line is the ideal choice for heavy truck air filters, this CNC-knife-based system is optimized for synthetic cabin air filters and high-end cleanroom elements.

This high-performance Automatic CNC Filter Media Feeding, Folding & Slitting Production Line is an advanced, fully integrated manufacturing system engineered for the continuous production of premium panel air filters, automotive cabin air filters, and cleanroom HEPA filters. It seamlessly combines automated raw material roll-feeding, high-precision CNC knife pleating, and inline longitudinal slitting (cutting) into a single, highly efficient process.

By synchronizing the material tension, reciprocating folding knife movement, and multi-blade slitting assembly under a centralized CNC system, this production line eliminates the need for separate, manual cutting and folding stations. It guarantees perfectly parallel pleat geometry, razor-sharp fold lines, and clean, burr-free slit edges, making it the premier choice for filter factories aiming for high-throughput 24/7 automated manufacturing.

Key Features & Mechanical Advantages

1. Integrated Feeding, Folding, and Slitting

The line combines continuous tension-controlled uncoiling, precise CNC knife pleating, and inline longitudinal slitting in one automated flow. This eliminates the need for standalone transfer machines, reducing labor costs and eliminating material edge damage during manual transit.

2. High-Precision Reciprocating CNC Pleating

Utilizes premium upper and lower reciprocating folding knives driven by high-torque servo motors. This mechanical setup ensures consistent pleat depth and perfectly parallel fold geometries across the full 1000 mm width without slicing or micro-cracking the fibers of delicate synthetic or paper media.

3. Flexible Inline Longitudinal Slitting

Equipped with 4 sets of adjustable high-carbon alloy slitting blades. The blades can be adjusted horizontally along guide rails, allowing the machine to slit the continuous pleated filter pack into multiple narrower lanes during continuous folding, producing clean, burr-free edges ready for framing.

4. Intelligent HMI & Recipe Management

All parameters—including the variable feeding tension, independent pleating speeds, slitting coordinates, and final cut-to-length piece counts—are managed through a centralized PLC touchscreen dashboard. Operators can save up to 50 distinct filter product recipes for rapid changeovers.

Applications & Industrial Uses

This automated CNC feeding, folding, and slitting line is widely deployed in production lines manufacturing:

  • Automotive Cabin Air Filters: Folding and slitting multi-layer synthetic and carbon-loaded media for passenger car climate control.
  • Cleanroom HEPA & mini-Pleat Elements: Producing high-precision, fine-pleated elements for cleanrooms, medical air handlers, and HVAC units.
  • Commercial HVAC Panel Filters: High-throughput manufacturing of standard pleated air purification inserts.

Why Partner with Fupei?

  • Strict Pre-Shipment Quality Inspections: Every CNC folding and slitting line is fully assembled and tested with actual filter media rolls at our factory to verify tension, folding, and slitting stability before dispatch.
  • Custom Voltage & Grid Compatibility: We configure the internal electrical motors, heating elements, and PLC systems to meet your regional industrial standards (such as 3-Phase 380V/50Hz, 220V/60Hz, or 415V/50Hz) for rapid on-site commissioning.
  • Global Technical Assistance: We provide a comprehensive 1-year warranty, complete electrical and pneumatic schematics, and permanent remote video troubleshooting support to ensure your workshop maintains continuous production.

Frequently Asked Questions

A: This continuous line is optimized for standard cellulose air filter paper, synthetic non-woven fabrics, and composite filtration media. For highly abrasive, heavy-duty fiberglass rolls, please consult our engineering team for customized blade configurations.

A: The high-carbon alloy slitting blades are mounted on a sliding horizontal rail. Operators can easily loosen the lock screws, slide the blades to the desired widths, and lock them back in place. We can customize additional blade sets upon request.

A: The line features an active uncoiling feed rack with an integrated pneumatic tension sensor. The PLC continuously reads the feed speed and compensates for roll weight, ensuring the media enters the folding knives completely flat and tension-stable.
