01 / AUTOMOTIVE ENGINE AIR FILTER PRODUCTION PROCESS
From raw materials to customer approval.
The production route is presented entirely in English and follows the actual process sequence used for PU-framed automotive engine air filters.
Pleating
Form stable pleat height, pitch and count with PLM-350A.
Cutting & Shaping
Cut the pleated media to the required filter size and shape.
PU Frame Molding
Dispense and form the PU sealing frame with PU-20F.
Curing & Trimming
Cure the PU frame with PLBL-60, then trim the edges.
Finished Filter & Installation
Check appearance, dimensions, fit and installation direction.
Customer Approval
Confirm samples before stable batch production.
02 / CORE EQUIPMENT

The core-machine visuals use the official PLM website product images and retain the approved PLM machine-body logo.
PLEATING01
PLM-350A
Full-Auto Filter Paper Pleating Line
A connected pleating line for paper feeding, forming and controlled output.
PU FRAME MOLDING02
PU-20F
Air Filter PU Dispensing Machine
Two-component PU dispensing for rectangular, round and special filter frames.
CURING03
PLBL-60
60-Station Automatic U-Type Rotary Oven Line
A long, continuous curing route designed to connect PU molding with trimming.
Cutting, trimming, conveying, molds and auxiliary equipment are matched after the filter dimensions, shape, capacity and factory plan are confirmed.
AUTOMOTIVE AIR FILTER MANUFACTURING EQUIPMENT
Car air filter making machines for a complete PU air filter production line.
PLM supplies automotive air filter manufacturing equipment for new filter factories and existing line upgrades. The solution can connect a filter paper pleating machine, filter paper cutting machine, PU dispensing machine for air filters, automatic curing oven, trimming equipment, air filter molds, PU end caps and production materials.

05 / COMMON QUESTIONS
Before you choose.
Can PLM help me build a new engine air filter factory?
Yes. Start with your target filters, dimensions, daily output, budget and available factory space. PLM can help connect machines, materials, molds, process, layout and operator training.
Can I keep part of my existing production line?
Yes. For an upgrade project, PLM can review the existing pleater, PU dispensing, curing, trimming and labor arrangement, then identify which equipment can remain and where the bottleneck is.
What information is needed before machine selection?
Send finished-filter photos or samples, dimensions, filter paper, PU frame requirements, target output, SKU quantity, factory layout and current production problems.
Can the line make different air filter shapes?
Different rectangular, round or special shapes may require different molds, cutting methods and process settings. The final configuration should be checked against actual samples or drawings.
Does PLM provide support beyond machines?
PLM supports material matching, molds, process planning, installation guidance, training, spare parts and long-term technical communication.
