For the production of profiles, UNION can provide different solution to the customers: single screw extruders for small productions and co-rotating twin screw extruders or Tandem systems for medium-high production.
Foam polyethylene material is very flexible which adapts perfectly to any type of shape. For the packaging industry these foam profiles are mainly used to protect, due to the high shock absorbing capability, for fragile glasswork, TV’s, audio sets, PC’s and printers. UNION offers complete extrusion lines with an hourly production up to 250 kg.
The foam polystyrene profiles are not flexible like those made in polyethylene, but rather rigid. The extrusion lines for XPS profiles need, after the die head, a calibrator with a sufficient length to calibrate the profile and cool it down gradually.
