The standard process to manufacture EPS insulation sheets is cutting EPS blocks using hot wires.
Today many EPS processors also use shape moulding machines, especially for production of perimeter boards.
The new regulations about the physical properties of EPS insulatione sheets can be studied at EUMEPS.ORG : download the "white book" from there, it´s all interesting stuff and you will need this info, if you are in EPS business.
For production of sheets with rebated edges, VIRO offers a new knife-cutter for dustless operation, leaving scrap material which can be recycled.
If you do not require large amounts of boards with ship-lap or tongue & groove edges, you can also use the VIRO StyroDesign XL contour cutters for manufacture of these products.
Easy design, nesting, integrated calculation and automatic setting of cutting wires : design and cut shapes with the VIRO StyroDesign systems.
