Hot Wire Cutters
EPS or expanded polystyrene is cut most efficiently with a hotwire cutter. These machines use a thin nicrome wire to vaporise the EPS without and physical resistance. This means that you can get acurate profiles cut with neglagable deviation. Uni-Cam SA produces highly efficient CNC Hotwire cutters, either 2 axis, 4 axis, have a rotary table, or have a shaped wire for carving. The 2 axis machines can cut perpendicular to the wire holders. The 4 axis machines can cut any point to point line between on wire holder an the other wire holder, which can move independantly of each other alowing you to cut a cone or a cone or a pyramid. The rotady table would allow you to cut round shapes quickly, and the carving head would alow you to do work much like a router can do.
We make two standard sizes of Hotwire, "2000 x 1200 x 1200" and "3000 x 2000 x 2000", but can also make custom sizes to your requirements.
Uni-Cam SA has a range of hot wire cutting systems. Our hot wire Foam Cutters are designed to cut EPS foams. The machine can be 2 axis or 4 axis.
2 Axis hot wire cutters can only cut perpendicular to the table (the legs are always opposite each other and the wire is always parallel. The shapes in the picture above is cut on a 2 axis hot wire cutter.
4 Axis hot wire cutters can cut free form shapes such as cones as the legs move independantly as well as the wire can can move to different hieghts on the two sides.
Materials and Profiles
To the left and bottom left are typical 2 axis cuts. Below are items that can be cut with a 4 axis machine.
