   Functions and applications of the two-stage PVC extruder

This two-stage extruder is suitable for processing temperature- and shear-sensitive plastics, such as PVC cable materials and specialty modified materials. Users can obtain high-quality products, maximum economic benefits, and flexibility.

 

  PVC Extruder Stability Settings

1) Twin-screw extruder temperature setting: 140-160°C, depending on the material;

2) Single-screw extruder stability setting: 125-145°C, depending on the material;

3) Thermometer: Set to the desired temperature, and hold for 40 minutes after the actual temperature reaches the set value before starting the machine. This softens residues inside the extruder and reduces damage to the equipment.

 

  Production:

1) PVC material is fed from a high-speed mixer into a screw conveyor. Crushed granules or powder are then fed into a twin-screw extruder via a feeder.

2) The parallel, co-rotating twin-screw extruder mixes the material evenly. At a temperature of 140-160°C, the PVC mixture is fully plasticized, mixed, and dispersed. The final extruded mixture is a melt (130-140°C), which is dripped directly into a single-screw extruder.

3) The single-screw extruder completes the extrusion and granulation of the molten material (120°C) under low speed, high pressure, and cooling conditions. During extrusion, the material temperature has dropped to 120-140°C. Air-cooled die cutting begins at this point to ensure the material does not stick to the die.

4) After cooling in a second-stage cyclone separator, the temperature of the pellets cut by the pelletizer drops to 35-40°C. The pellets are then fed to an extended air-cooled vibrating screen, where their temperature is cooled to room temperature. Finally, the pellets are sent to a hopper for packaging.

Gently shear, press, and extrude PVC material to achieve PVC granules/masterbatch of the desired quality.

 

  Two Stage PVC Extruder Function and Application

▶ Soft and rigid PVC:

PVC cable insulation, sheathing and filled compounds;

shoe and shoe sole material;

alloys and blends;

▶ Special compounds:

HFFR;

compounds for elastomer-based cable'

cross-linkable PE.

 

  Two Stage Extruder Working Principle：

PVC extruder adopts aggregate wet pelletizing method to produce PVC granules/masterbatch. By using certain content of water or steam to make the resin get wet inside the barrel to react, the extruder will press and shear the PVC particles till it aggregate into small ball with screw rotating under desired liquid phase.

 

  Features and Advantages

1. Good feeding ability,even with poorly flowing powders and hot premixes from the high-speed mixer;

2. good homogenization and controlled shearing ability;

3. short residence time and defined narrow residence time distribution;

4. exact temperature control;

5. gentle product treatment, especially in the pressure build-up zone before the die plate;

6. even melting material flow through the die plate;

7. low energy requirement and easy to change for new requirements;

8. easy and convenient maintenance.

2)screw extruder for WPC;

3)screw extruder for XPS, for building material production;

4)screw extruder for snack food industry;

5)Two stage extruder for special application;

6)twin screw extruder for powder paint, various cable materials;

7)Spare parts such as barrel, screw element, spline shaft and gearbox;

 

Quality Control

Extruder main parts should serve to the following aspects and realize stable machine funtions:

 

To achieve this goal, these areas must be rigorously examined:

 

 

Placing order

We have a complete system for order control as shown below, but pls pay attention to your plastic material, process, industry voltage, weather conditions when you are order. These are some factors will affect our machine configuration and actual running.

 

 

 

Machine Operation

Pls refer to the drawings and instruction to install and work on the machine;

Donot start the machine before you start the electric cabinet;

Donot touch the machine shell during production;

Do not open the extruder only by the professional personnel;

Do change oil as needed and regularly;

Every month or week check the machine, keeping it in good condition.
