Hot Cutting Wire
Resistance wire is used as a hot cutting wire for the accurate cutting of complex shapes from polystyrene foam (EPS) and extruded polystyrene (XPS). Depending on the application, the resistance wire is generally a special nickel alloy or a stainless steel, and is heated to approximately 200°C by electrical resistance.
Hot wire cutting is used extensively in the packaging industry and for cutting shapes for R&D prototyping, modelling and architectural mouldings.
