Cast Extruder
This extruder has T shape die, and has excellent dimensional stability through forming film by contacting melted material into surface of frosted chiller roll by extruder, and it can produce high-transparency, high-gloss film with high speed.
Characteristic of Samdong Industry Product
  • Maximizing function of each layer because it is possible to design each layer to have different characteristic
  • Minimizing product deformation according to contempt after productionthrough activating In-line mature system
  • is possible to manufacture from low point to high point by Dual Manifold Die structure
  • Preventing Gel occurrence invading film by introducing Polymer Filter system, and it can inspect micro foreign material by installation 10 detector in every facility.
Condition of Cast Extruder in Company Production Capacity Condition
  • Equipment possession condition :3(2 is for optical, 1 is for stretch wrap
  • Production Capacity : 65 ton per day
Extruder Process

1. Polymer Filter


Process that filters out micro foreign material like Gel in materials.

2. T-Die Head


Process that makes melted material into film

3. Chill Roll(Frosting Roll)


Process that freezes flowing down film from die quickly

4.Thickness Measurement


Process that inspect real time to make every thickness evenly.

Annealing


Process that matures film not to transform by adding certain heating.

6. Corona treatment


Process that penetrates high frequency, high voltage into surface of film.

7.Foreign Material Detection Sensor


Process that detects foreign material in film.

8. Winder


Process that wraps produced film.
