Heat inside the battery module
Aerogel and PC flame-retardant sheet are cut to the module drawing, so the barrier covers the area the print specifies.
Aerogel, FPC stiffeners, flame-retardant sheet, display adhesive, VHB foam tape, gaskets, and vents for new-energy vehicles.
Application
A new-energy vehicle carries two kinds of die-cut work. Around the cells and circuits sit aerogel, FPC stiffeners, PC flame-retardant sheet, and brown insulating film. Around the cabin sit display adhesive, VHB foam tape, gaskets, and foam that must hold through heat, cold, and years of vibration.
Both lists come straight from our company profile. Automotive products are named in our company scope, and the profile gives new-energy parts their own pages. Both are converted on the Dongguan floor beside the 3C work, on the same registration lines and checked on the same inspection bench.
Automotive drawings are exact, and lots repeat for years. We cut a laser first article for the fit, hold the shape on a flatbed press or the ten-station rotary line, and check each lot with vision measurement and adhesive tests before it ships.

The problems buyers in this industry bring to the plant, and how the floor handles each one.
Aerogel and PC flame-retardant sheet are cut to the module drawing, so the barrier covers the area the print specifies.
Holding power, tack, and peel are measured on Hualiang instruments for each adhesive job.
Tooling is held for the part, and 2.5D vision measurement checks the outline lot after lot.
Foam, tape, gasket, film, and vent are converted under one roof, so one supplier can quote the set.
Photographed for the company profile. Shapes are customer-specific, so treat them as examples of the work, not stock items.
Delivery formats
Tell us how the part goes on: by hand, in a fixture, or from a web. Each format below comes from a named machine on the floor.
Kunlun KL-QP-350 sheet cutters × 2
Parts kept on a carrier sheet, counted and stacked, for hand placement or low-volume fixtures.
Kunlun KL-FTJ-1300 CNC slitter, Hadesheng rotary
Parts cut on a continuous web and wound to width, for long runs and feeders that pull from a roll.
Kunlun and Hongwen laminators × 16
Membrane, mesh, foam, or film combined with adhesive and liner before the cut, so one part replaces several.
