How to produce pleated filter cartridge ?

1. Filter paper machine to make filter cartridges pleat.
2. Side Seam Thermal Welding.
3. Cartridge shape.
4. End cap welding
5. Fitting end cap welding and filters length connecting welder Fitting end cap.
6. Length connecting.

Putting quality lab tested filtration media with suitable width on a roller, pleating machine starts making some plates as trial running to adjust pleating speed and pleating height.

The cutter of the pleating machine set to cut off a certain length of pleated membrane. One worker will gathering the pleated membrane into a box and forward to next procedure.

This type of water filter cartridges are available in a wide range of chemical compatibility.

Filter paper machine to make filter cartridges pleat.

Pleated design increased the filtration area for deep filtration.

The large diameter with big filter area insures to reduce the number of filter cartridge and dimension of housing required.

All pleated filter cartridges are made from high purity polypropylene materials and manufactuered and assembled in a clean environment to minimized the possibility of containation.

Side Seam Thermal Welding

Prepared pleats.

Cutting off the surplus length on both sides of the thermal welded pleated membrane to make sure it is 20/40/60 inches long to fit the cage and end caps. Length control is important for the filter cartridge integrity. Too long which will affect flow rate or too short which cause leakage in the filtration process.

Middle seam welder to do seam thermal welding of filter cartridge paper

Ultrasonic thermal welding is a high technology for side seam sealing of membrane pleated, without any additives & glues in the process which making sure 100% integrity of side seam and no any pollution. Keeping clean and stable for the membrane pleated cartridge filters and high flow pleated filter cartridge in filtration process.

Shape

Cartridge shape

Putting the suitable length pleated membrane which contains an inner core inside into the outer cage.

Assembled Semi-finished filters which placed neatly to clean and tidy box, waiting for the next step.

End cap welding

To welding Flat cap onto both ends of filter cartridge, which makes pleated membrane, inner core & outer cage together as 100% integrity.

Fitting end cap

Fitting end cap

Putting the end caps on both ends and filter cartridge in the middle of end caps thermal welding machine. Setting suitable temperature, Two end caps which could be fin, 222, 215, 226 move forward to the middle and get in touch with a flat cover. A few seconds later, end caps, pleated membrane and outer cage & inner cage are thermal welded together to form a complete pleated filter cartridge.

Length connecting

Length connecting

Welding 2/3 pieces together to complete 40/60 inches long high flow pleated filter cartridge, so that all the part of the pleated filter cartridge is thermal welded together, complete the production of membrane pleated cartridge filter.
