Plastic Sheet Extrusion Process

Plastic pellets are fed into the barrel of the extruder and conveyed by the screw, the heaters which are outside of the barrel of the extruder as well as the friction from the rotation of the screw melt the plastic pellets into a sheet mold and then placed on a three-roll calender, the produced sheet goes through the bottom and middle roll,wrapping around back of the middle roll and then back to the top roll or other methods as shown in sheet calender picture, these rolls are helpful to take the heat out of the sheet, after the sheet comes off the roll,it moves down the conveyor to the end of sheet line where the edge trimmer cuts the sheet to width as well as a sheet shear cutter to length.

Plastic sheet production line adopts different screw designs and mechanical configurations to be suitable for manufacturing a variety of plastic sheet (eg:PP,PE,PS,ABS,PMMA,etc.)

PET is used widely in plastics processing fileld because it has good transparency,high impact resistance,easy recyclables and many other excellent process friendly properties. Usually PET sheet extrusion line have up to three layer and 2 or 3 extruders.While the centre layer of such products can contain a high percentage of recycled material,the outer layer consists of virgin resins combined with additives.

1. Extruder: special design of screw, precise temperature control system, good plasticization, high output and stable extrusion

a. Sheet extruder contains screw and barrel made from alloy steel duly nitrided and hard chrome plated for long life.

b. Screw is driven by AC motor and coupled throngh a suitable standard make gear box.Barrel is divided into zones for heating load distribution.

c. Cooling blowers are provided on the barrel for all zones.

d. Water circulating jacket is provided in feeding zone.

2. Screen exchanger: hydraulic, fast and efficient changing

3. T-die: high grade alloy-steel material, multi-channel design and adjustable die lip gap

a. A flexible lip adjusting system to provide an uninterrupted flow surface in the lip area.

b. The lip is flexed to adjust the gap,the bolts always remaining in compression eliminate thread slack and resulting loss of sensitivity inherent to push-pull system.

c. All stainless steel construction provides corrosion resistance.

4. Three-roll calender: horizontal/vertical/tillted roll arrangement, adjustable roll gap to ensure calender effect and equipped with roll temperature controller

5. Cooling frame: cold roll, fan cooling and equipped with siding trimming

6. Winder: equipped with high quality torque motor, adjustable rewinding speed and tension

Plastic sheets produced from this type of extrusion equipment are sturdy,yet remains somewhat flexible.
