Product Description

China Factory Price HDPE PP PE PPR Plastic Single Screw Extruder

Single screw extrusion uses one screw within a cylindrical barrel to continuously push plastic through a constant profile die. Production rate is typically measured in mass per hour (lb/hour or kg/hour) and is controlled by the screw speed of the machine.Single-screw extruders are used extensively in the plastics industry for melting polymers,incorporating additives (for example fillers, colouring pigments, stabilizers) and delivering a homogenized melt at high pressure to a die prior to shaping processes.

Main Features

1. Modular principle design for screw configuration and barrel setup makes combination and cleaning convenient , also easy to adapt to customers' requirements .
2. Different kinds of pelletizing modes can meet specific material properties: water-cooling strand pelletizing, air-cooling hot-cut pelletizing, water-ring pelletizing, under water pelletizing, etc.
3. Screw elements and kneading blocks are made of high tool steel , with high corrosion-resistant and high wear-resistant.
4. Barrels are made of high quality nitrided steel , corrosion proof and antifriction.
5. Vacuum system fulfills devolatilization to ensure the quality of polymer processing.

Detailed Photos

1. Euro-style retangle barrel, reflux refrigerationchannel is optimized and disposed, which makes temperature difference in C areas smaller. Innovated design of heater tightened style insures high efficiency of heat tansfer and high longevity of heater. The barrels are equipped with bimetallic liners( 45# steel + α101), processing heat treatment. HRC is between 60 and 62.

2. The screw elements and kneading blockes are designed accurately, precised processed by our workers in our plant. The material of screw elements is high-speed steel W6Mo5Cr4V2, or 38CrMoAlA , under nitrogen treatment, HRC is between 58 and 60.
 
3. Reducing and distributing gearbox of extruder reduces the motor speed to the speed of the screw shafts and distributes it to the two output  shafts.
The gearbox consists of:
Involute gear teeth couplings between the output shafts and screw shafts
Integrated thrust bearings assembly, radial bearings of the output axis are NSK products.

4. PLC or PCC controller.

   Hopper Dryer

 

The advantages of this hopper dryer are as follows: stable and reliable electric performance, precise temperature control, 24hours automatic running set, low energy consumption and high efficiency, etc. 

If your granules are moist, you can use this machine to dry the granules, and you  donnot to do that, the machine can also serve as normal dryer.

  Single Screw and Barrel

 

It has high speed and high output design for single screw extruder. The single screw is very important for the extruder. We can also provide good designs for our customers.

   PLC Control

Digtial PLC control To Realize automatic control for complete production line

    Coupling

The coupling is used to connect two shafts together at their ends for thepurpose of transmitting power.

   Gear Box

Gearboxes are used for increasing torque output or changing motor speedApplications that need a high horsepower require the use of industrialgearboxes and geared motors

   Siemens Motor

SIMOTICS electric motors are synonymous with quality, innovation and the highest efficiency

   Heating System

The barrel adopts 4 sets of heaters, and the head is equipped with 4 zoneheaters
Heating power: 3-AC380V, 50HZ
The heater is covered with astainless steel safety cover

   Cooling System

Water cooling will be efficiency and stable
