Cartridge filter end cap welding process:
Step 1: use SIIC-M025-ECWH to weld common end caps onto both end of half -finished cartridge filter, here half-finished cartridge filter means pleats installed into inner core and outer cage.
Step 2: use SIIC-025-EW to weld 222, 226, spear and flat cap onto cartridge filters.
Tips: When you want to produce 20inch, 30inch and 40inch long cartridge filters, length connector welding process is necessary.
