How and Where a Single Screw Extruder fits in Polymer Processing?

Single screw extrusion is one of the primary types of polymer processing. The main function of a single screw extruder is to create pressure in the polymer melt. With a single screw extruder manufacturer company like Neoplast, it becomes easier to process various types of polymers.

Undoubtedly, plastics play a key role in all aspects of modern life. From health and well-being to safety and security, plastics are integral to our everyday life.

A majority of the single screw extruders ensure that solid polymer compounds melt in the screw due to the pressure. However, other single screw extruders are ideal for mixing polymers too. A single screw extruder is pretty essential in processing high-density polymer compounds.     

Working Mechanism of a Single Screw Extruder

Note that single-screw extruders have extensive applications in a plastic recycling machine. The working principle of the single screw extruder is to heat the thermoplastic to melt it properly. Moreover, single screw extruders ensure that the material moves forward through pressure.

So as you can see, single screw extruders have extensive applications in cooling the polymer mould and rendering it the final shape. Based on its working principle, a single screw extruder usually has four parts:

• Extrusion system
• Cooling and heating system
• Electrical control system
• Transmission system 

Usually, the extrusion system contains a screw, a barrel, a die, a head and a hopper. The plastic raw material processes the polymer into a final mould.

The screw is also known as one of the integral components of the extruder. The performance of the screw determines the productivity. Moreover, the dispersion of additives associated with polymer processing is also closely associated with the extruder.  

Evolution of Extrusion Screw Design over the Years

No doubt, the design of a single screw extruder has been evolving over the years. With the introduction of new ideas and innovations, single screw extruders are becoming more effective and efficient. In addition, single screws are available with secondary flights.

The secondary flights improve the overall efficiency of the extruder by enabling faster melting. Single screw extruders come with a wide variety of accessories like vent vacuum units, pressure and heat controllers, etc. Here are some features of single screw extruders one should know. 

• Extruders feature a start and stop button
• Extruders include a feeding capacity
• Diagnosis and maintenance alerts 

Polymer processing is changing the way we use plastics in our everyday lives. Polymer processing with extruders enhances the properties of the polymer. Polymer processing is undoubtedly one of the best ways to manufacture plastic moulds of varied types. Hence, it is evident that polymer processing is one of the most sustainable.
