Characteristics

1. This production line can produce three or five-layer co-extrusion non-PVC infusion film.

2. It adopts high torque motor to drive machine. The barrel has insulation design, which is energy saving and efficient.

3. The control system adopts B & RIPC, which is easy to operate.

4. The process parameters can be automatically remembered and stored.

5. It has clocking heating function.

6. The width of film can be easily adjusted, simply needing to replace sizing water ring.

7. The thickness of film can be automatically controlled.

8. Receiving and winding rolls are automatically controlled.

9. The equipment adopts stainless steel, meeting the requirements of GMP.

Automatic feeding system

Weighing-type automatic feeding, set the proportion of each floor through the touch screen, the feeder automatic weigh for feeding, feeding is accurate, ensures the film thickness of each layer. Feeding system is also with drying function, according to the humidity of the material to do the drying.

Co-extrusion die performance characteristics

1. Using today's most popular European and American low-motif design

2. A single channel to dual channel flow distribution of molten material

3. Spiral feeding

4. The short melt flow channel

5. No plug flow, no hanging dead material

6. The short residence time of molten material

7. Strong self-cleaning materials, cleaning with less material

8. No parting line

9. Low pressure drop

10. No leakage between layer and layer

11. The die assembly and disassembly easy cleaning, customers can operate by themselves
