Pleating & Mesh LineThree processeson one line
Upper and lower reels feed automatically; after hot-roll forming the mesh is assembled and stacked — no manual transfer; pleat height, pitch and mesh width are set on the touch screen per element spec, pleat height 19–76 mm.
In-house R&D
Pleating and gluing structures designed in house, customised to your element
Turnkey line
From single machines to a full line, cycle times matched and layout done once
CE compliance
Electrical safety and EMC meet EU directive requirements

Products
Six main machine types cover element forming for oil, air and hydraulic filters. Specs are standard-machine ranges, adjusted to your media and element size.
Filter Paper Pleating Machine
Standard pleating model with hot-roll forming, for regular pleat heights and pitches.
- 5–100 mmPleat height
- 0–120 pleats/minSpeed
Fully Automatic High-Speed Pleating Machine
Continuous feeding with pre- and post-pleating in one pass, for volume production of medium and large elements.

Three-Axis Automatic Dispensing Machine
Spot gluing on irregular end caps and seals, with programmable paths.
- 600×400×150Stroke
- ±0.02 mmRepeatability
Fully Automatic Filter Element Production Line
Pleating to inspection on one linked line, centralised PLC control, 1–2 operators.
- 1,200 pcs/hCapacity
- 1–2Operators
Four steps, one line ready to produce
A line is not a pile of machines. We first calculate cycle time from the element structure, fix the process, then specify and place each machine.
Pleating
Roll temperature, tension and pleating rate are set by media weight and pleat height, keeping the whole roll consistent.
End-cap gluing
PU or hot-melt adhesive is dispensed by volume with closed-loop control; missing or broken beads stop the machine and alarm.
Assembly & curing
Element, end caps and centre tube are assembled in place; constant-temperature curing secures the bond, with quick-change tooling for many sizes.
Inspection
In-line leak test plus appearance and dimensional sampling; data is archived for traceability and rejects are ejected automatically.

Automated Filter Production Line: Empowering the Filtration Industry with Quality and Efficiency Enhancement
As core consumable components in automobiles, construction machinery, and industrial hydraulic systems, the quality of filter elements directly impacts the operational stability of host equipment, while filter production equipment serves as the fundamental basis determining filter quality. With the upgrading of manufacturing industry, traditional single-machine manual production modes are gradually being replaced by automated filter production lines, driving the industry's transformation from labor-intensive to digital manufacturing.
Filter Testing Equipment: Safeguarding the Quality Control Line for Finished Products
Filter production cannot focus solely on molding and assembly; performance testing equipment is an indispensable link in controlling product quality. Regardless of the automation level of the production line, without professional testing equipment, it is impossible to effectively identify hidden defects such as seal leakage, substandard flow resistance, and insufficient pressure resistance.
Key Points for Filter Equipment Selection to Facilitate Rational Investment for Filter Enterprises
Many operators planning to establish or expand filter manufacturing plants often fall into misconceptions during the equipment procurement phase, blindly pursuing high production capacity while neglecting product compatibility, resulting in idle equipment and capacity waste.
