Screw Barrel Types & Functionality

Where there is plastic making machinery; there is a screw barrel. That much essential is the role of screw barrel in the industries especially in plastic manufacturing. But as the plastic differs in sizes, shapes, materials, quantities, there is more than sufficient availability of screw barrels.

These are the some of the many types of screw barrels:

•    Single Screw Barrel

-A single screw inside the barrel.

 .      Twin Screw Barrel
-Two screws attached together inside the barrel.

  .      Barrier Screw Barrel
-Manufactured with the use of advanced CNC machine.
-Less maintenance
-Highly productive

  .      Vented Screw Barrel
-Refined chemical and physical properties.
- Special carbide coating on screw flight and bimetallic barrel

  .      Bimetallic Screw Barrel
-Two types of bimetallic coating.
-Coating of 1.5mm.
-Bimetallic layer hardness is of 55HRC and 72HRC.
 
 .      Twin Parallel Screw Barrel
-Nitro alloy material is used
-Maximum length is upto 4.5 meters.

 .      Extrusion Screw Barrel
-Length of 5 meters.
-Uniformity of the products remains unchanged.

Applications:

-Extrusion plants

-Injection molding machinery and plants

-Rubber molding machine

-Plastic extruder machine

-Plastic processing machine

-PVC pipe making plant and machinery

-Cable machineries

Comparison Between Single Screw Barrel & Twin Screw Barrel

single screw barrel

As the name suggests, the noticeable difference between a single screw barrel and twin screw barrel is that number of screw used to manufacture the entire tool. In single screw barrel is comprises of only one screw while the other contains 2 screws inside a barrel.

Also there comes the variation in the length and width. As the twin screw barrel contains more screws than the first one, it is usually bigger in size. The maximum length of the barrel in the twin barrel is 6000mm as in single screw barrel it is 5000mm.

Twin screw barrel

Applications:

Single screw barrel is mainly used in plastic processing machineries such as injection moulding, blow moulding, plastic extruding, etc. While twin screw barrel is used in the parts of injection moulding machinery, plastic extrusion plants, PVC pipe making and many more.
