What is twin extruder?

The twin screw extruder is a classic machine and it mainly utilized for the process of plastic extrusion, when two or more ingredients are compounded or mixed. This process is highly suited while extruding the reactive polymeric materials. More specifically, the twin extruder is more useful in the manufacturing of rigid PVC as well as wood fiber mixture. Usually, this kind of extruder is able to guarantee the mixing, cooling, heating, transporting, pumping, compressing, shaping, cooking, etc. with a greater level of flexibility.

A mechanical shear from the twin screw as well as thermal heat from a barrel can convert the sturdy polymer into melt that is forced out of a die. When compared to the single screw extruder, the twin screw extruder is more effective in offering the homogeneous combination of diverse ingredients such as liquids, fillers and additives. Some of the great features of twin screw extruder are given below:

·      Softening water auto cycle cooling system goes through barrel

·      Fine powder rework ability

·      Best quality gear with great stability and less noise

·      PID temperature control system

·      Equipped with sturdy permanent magnetic iron remover

The function of single extruder

A single screw extrusion is one of the major techniques utilized for processing the materials of synthetic plastics both in molten and powder form. The single extruder is majorly utilized to enhance the quality of melt and also maximize its production by making pressure in a molten polymer.

At present, many of the extruders are solo screw machines. This screw is actually pushes the substance towards and also via the die. Here, outline is imparted by a die or by post extrusion making and a product is setting to form by cooling while keeping its shape.

The materials enter from hopper into a feed throat are conveyed by a rotary motion of the single screw. The mechanical shear from a screw as well as thermal heat from barrel can convert the sturdy polymer into melt that is forced out of a die. In the single extruder, the granular materials remain longer in an extruder, which slows down the time of production.
