FAQ
Parallel Twin Screw Extruders FAQs-The Complete Guide
Here is an FAQ guide for your understanding the basics of parallel twin screw extruder.
Parallel twin screw extruders are in huge demand for compounding modified plastic wood-plastic.
The guide comprises all the details related to parallel twin screw extruder.
Q1. What are Parallel Twin Screw Extruders?
There are two types of parallel twin screw extruder in the market, which are co-rotation twin screw extruder and counter-rotating parallel twin screw extruder.
The counter-rotating A parallel twin screw extruder is a wide used in plastic pipe extruding line, plastic profile extrusion line, plastic board extrusion line and SPC flooring extrusion line.
Figure 1 Parallel Twin Screw Extruder
The co-rotating twin screw extruder is mainly used for compounding of plastic and to modify different plastics.
The co-rotating parallel type has high speed of 1000rpm and normal speed of 600rpm.
They have parallel screw barrel, so we call both of them parallel twin screw extruder.
Q2. What are the Different Components of Parallel Twin Screw Extruders?
There are different components of parallel twin screw extruder, including the following:
Figure 2 Parallel Twin Screws
Figure 3 Gear Box of Parallel Twin Screw Extruder
Figure 4 AC Motor for Parallel Twin Screw Extruder
These parts are generally present in all the parallel twin screw extruders by all extruder machine manufacturer.
Q3. How Does a Parallel Twin Screw Extruder Work?
Figure 5 Working of Parallel Twin Screw Extruder
The working principle of parallel twin screw extruder is not different from conical twin screw extruders. In it, its barrel is driven by motor whereas the extrusion material enters through hopper.
Though the structure of parallel twin screw extruder is different from single screw extruder yet their working way is same.
Both run by motor and gearbox reduces the speed, however parallel twin screw extruder has higher requirements and standard.
Q4. What are the Features of Parallel Twin Screw Extruders?
The key features of Wecoex parallel twin screw extruders make them unique and different from other market products. These features include:
- They are capable of producing masterbatches, plastic products, and to recycle pellets.
- They give a higher output value than other extruder manufacturer.
- Parallel twin screw extruders have a capacity of extruding 150kg/h-2000kg/h.
- The power consumption is also low because of AC motorsand high quality VFD.
- The screw barrel can be customized dimensions for custom orders.
Q5. What is the Purpose of Using Parallel Twin Screw Extruders?
The most common purposes of using parallel twin screw extruders are masterbatch production, compounding of wood-plastic, PVC products and compounding of plastic pretty fast and efficiently.
However, all parallel twin screw extruder require connection with molds and different down-stream machines to produce various products.

Q6. Why Does a Parallel Twin Screw Extruder Mix Better than a Single Screw Extruder?
Wecoex parallel twin screw extruders are always very efficient in mixing as compared to single screw extruder.
It is mainly because of the presence of two intermeshing screws instead of one, the material can be mixed between the two screws.
Figure 7 Comparison of Single Screw and Parallel Twin Screw Extruder
Also, the screws of parallel twin screw extruders are designed in a way that prefers the mixing and meshing with precision it means that there is not enough gap between the two screws.
The plasticizing capability of a parallel twin screw extruder is also far better than the single screw extruder.
Q7. How Does Starve Fed Improve the Efficiency of Parallel Twin Screw Extruders?
The machines like parallel twin crew extruders are given starve-fed.
It is due to the fact that it increases the melting action of the compounds.
Also, it enhances the mixing action.
Initially, the extruders are not filled completely with polymers so that the pressure does not get a chance to develop there.
Later, the polymer is fully fed and adequate pressure is built inside the machine to push it to the die.
The working efficiency of parallel twin screw extruders is enhanced by starve feeding process.
It is a process that allows the addition of plastic monomers is not as a whole fed into the extruder machine.
Figure 8 Starve Feeding Operation
Instead, in starve feed, you feed the monomers gradually into the parallel twin screw extruder vessel at a steady rate that makes the monomers used by the reaction before the entry of the next monomer batch.
Q8. How Can You Choose the Right Parallel Twin Screw Extruders for Your Products?
Well, it depends on the the plastic products you want to produce.
There are so many options available in the market for parallel twin screw extruder, and we list some key points that you must have in mind.
- The products you want to make and raw material.
- Check the output range of the extruder.
- Check the brand name of main parts, like screw barrel, gearbox, motor and electrical parts.
Q9. How Can You Purchase a Parallel Twin Screw Extruder?
