to products listRW 41 Ultra High
Strength Hot Cutting Wire
This wire has exceptional strength at elevated temperatures and is
the ultimate highest performing hot cutting wire. It is used on
production lines cutting polystyrene (EPS), thermal laminate materials
etc. It has an excellent track record for working on machines running
24 hour shifts and on oscillating cutting frames.
To achieve the best cut, adjust the wire temperature and the speed
of the block through the wire. The material type and it’s density will
influence the cutting speed.
