What are the advantages of plastic extruders? – Suzhou Polytime Machinery Co., Ltd.

A plastic extruder is a piece of plastic extrusion equipment that melts and extrudes plastic raw materials. The materials are continuously extruded in a flowing state through heating and pressurization. It has the advantages of high efficiency and low unit cost. It is necessary equipment in the production line of molded plastic trays. It is suitable for all kinds of waste plastics, plastic films, plastic particles, and other raw materials. In recent years, it has been widely used in the field of waste plastics recycling.

What is the extrusion principle of plastic extruder?
The working principle of the plastic extruder machine is to use the screw of a specific shape to rotate in the heated barrel to squeeze the plastic sent from the hopper forward to make the plastic plasticized evenly (also known as melting). Through the head and molds of different shapes, the plastic is extruded into various shapes of plastic layers required for continuity and extruded on the wire core and cable.

What are the advantages of single screw extruder?
The single screw extruder has the advantages of advanced design, high quality, good plasticization, low energy consumption, low noise, stable operation, large bearing capacity, and long service life. The single screw extruder adopts a two-stage overall design, which strengthens the plasticization function and ensures high-speed, high-performance, and stable extrusion. The comprehensive mixing design of a special barrier ensures the mixing effect of materials. High shear and low melt plasticization temperature ensure the high-performance low-temperature and low-pressure metering extrusion of materials. In addition, the design price of a single screw extruder is cheap, so a single screw extruder is widely used.

What are the advantages of the twin-screw extruder?
Compared with a single screw extruder, a twin-screw extruderhas many advantages in reducing production costs and improving production efficiency.

1. Reduce production costs

When the color of the split twin-screw extruder is changed, the barrel can be quickly opened for manual cleaning in a few minutes, so that the cleaning material can be used without or less, and the cost is saved.

2. Improve production efficiency

When maintaining the split twin-screw extruder, just loosen a few bolts, turn the handle device of the worm gearbox and lift the upper half of the barrel to open the whole barrel for maintenance. This not only shortens the maintenance time but also reduces the labor intensity.

3. Wear

The twin-screw extruder is easy to open, so the wear degree of threaded elements and bushing in the barrel can be found at any time, to carry out effective maintenance or replacement. It will not be found when there are problems in the extruded products, resulting in unnecessary waste.

4. High torque and high speed

At present, the development trend of a twin-screw extruder in the world is to develop in the direction of high torque, high speed, and low energy consumption. The effect of high speed is high productivity. Split twin-screw extruder belongs to this category and has unique advantages in processing high viscosity and heat-sensitive materials.

In addition, a twin-screw extruder also has the advantages of a wide application range and can be suitable for the processing and production of a variety of materials.

Different design concepts are produced due to different application requirements. Single screw extruder and twin-screw extruder have their advantages and disadvantages. Therefore, they can be applied in different fields and give full play to their advantages and effectiveness.
