SPU / Sheet Manufacturing Direct Extrusion System
Direct extrusion is new system, using twin screw extruders improving on simplified process and space saving.
It is variably adopted from the general-purpose sheet and film to the optical.
Features
1. Enhanced pormance
- It has the outstanding high compounding and high dispersion, and can process simultaneously possible in two or more material.
- Operation conditions are very large and many resins can be responded.
2. Improved functions
- Operation conditions are very large and many resins can be responded. Since TEM-SS series has Super-High torque, low-speed extrusion and low-temperature fabrication are possible for it, and it can supply quality sheet and film product.
- Since there are many throughput of extrusion per screw rotation, the mass extrusion in a small machine is possible. It can respond to space saving.
3. Saving energy
- Compared to single screw extruders, less specific energy results in decreased running cost. (Saving electro power)
- The loss of the raw material switch can be decreased to quick change in the operation conditions, and the raw material price be saved.
