Heat cutters are ready to use after just a few seconds to heat up. These tools include polystyrene cutting guns and plastic cutting guns. They have metal cutters that are heated up then almost glide through the material to be cut on their own. Polystyrene cutting guns are used for cutting all types of hard foam. They can be used to cut heat insulation plates for houses, among other materials. Plastic cutters are suitable for cutting, separating and welding synthetic materials. They can be used to process string, belts and ropes, as well as braided sleeving. Compared to cutters or knives, heat cutters are faster and more precise, and they do not create any dust.
