What is a hot knife used for?

Hot knife cutters are used for trimming, cutting and edge-sealing plastic, fabrics, polystyrene, rubber, tyres, rope, plexiglass, foam (including styrofoam) and other materials using the heat of the blade to seal as it cuts. It’s therefore ideal for cutting reinforced materials to help stop them from fraying.

There are dozens of applications that require a hot knife or foam cutter to cut and trim the material, many of them where expanded polystyrene is in use and needs to be cut and shaped before fitting.

Hot wire cutters are also used in the vehicle industry for upholstering as well as for cutting webbing and finishing along with cutting of vehicle trim.  Bonded car windscreens are also removed with the use of hot knives.

Construction sites also have a use for a high quality hot knife in order to process insulation material, substantially reducing the amount of hazardous fine dust.

There are a range of blades available to suit different jobs and shapes of cut (e.g. cutting webbing, deburring of injection moulded parts, ribbon and fibre optic terminations, trimming and radius cutting, low temperature thermoplastics, foam, gasket material and adhesives to name a few)
