RW 118 / RW 122 / RW 70 High Strength Hot Cutting Wires

These hot cutting wires have high strength at elevated temperatures and are used for cutting foam polystyrene (EPS) and or heat sealing woven polypropylene bags.

To achieve the best cut, adjust the temperature and cutting speed. The material type and it's density will influence the cutting speed.
