- Model NO.: SJ-75 TO SJ220
- Plastic Processed: EPE
- Type: Sheet Extruder
- Screw: Single-Screw
EPE sheet machine adopts advanced butane physical foam technology with high foam rate. Product is the popular soft packing material in the market which is the many excellences, such as: Moistureproof, shockproof, sound insulation, heat preservation and good plasticity. It's widely use for packing electronic product, glass, porcelain, furniture, commodity, etc. Also it can be used as pad of bag/box, floor-pad, sport-pad and heat preservation layer of refrigeratory.
Machine adopts explosion-proof motor, intelligent digital meter with safe and stable running, easy operation. Various EPE foam sheets can be produced continuously. And it can be produced foam pipe, stick and net if change relevant die and mould
1. Screw: It is made of the top quality 38CrMnALAn azotized steel. Thermal and azotized treatment and special surface plating make the screw is with high intensity, high rigidity and long life. The screws diameter is 105mm, length is 4740mm (two-sect style), L/D=1: 55. This feature improves the plastifyig ability and quality of the screw.
2. Material-Feeding Sector: Two ends of it are connected to the cylinder and gear box. From here the raw material is sent to the extruder. The user should keep some cooling water in circulation in order to prevent the temperature arising, which will result in pastiness, agglomeration of the raw-material, and even block the material-feeding hole.
3. Butane Input and Butane Pump: The butane pump is a high pressure measuring pump. This pump jets the deliquesced butane into cylinder by a high-pressure of 100-150Mpa.
4. Input of anti-shrinkage and anti-shrinkage pump: The anti-shrinkage pump send the heated anti-shrinkage into cylinder by a pressure of 10-15Mpa. The melted anti-shrinkage mixes with LDPE in the entrance of anti-shrinkage.
5. Die-Head: Melted raw material is extruded from here. The raw material starts to foam when goes through the die-lip. The thickness of EPE sheet depends on the die-lip and pulling speed.
6. Shaping drum: The thickness of EPE sheet depends on this part. So the cooling water, cooling air are provided by this part.
