Cellular foam & sponge rubber extrusions
Cellular foam, neoprene & sponge rubber profile, tube & cords can all be cut with our range of Servo-Torq® fly-knife rotary cutters.
Typical products include sealing profiles for doors & windows.
Rubber compounds include EPDM, Natural rubber (NR), Nitrile rubber (NBR), Chloroprene rubber (CR) & silicone. Self-adhesive strip backed profiles can also be cut.
Due to the soft, elastic, nature of the foam material, it usually needs special handling. This includes custom made knifes & cutter guide bushes.
To achieve any degree of cut length accuracy, it is essential to locate a sonar loop control unit before the Servo-Torq® cutting machine when handling this type of product. This ultra-sonic device allows the extrusion to relax before it enters the cutter. Without it, the cut length variation will be excessive due to product stretch.
