Extrusion Basics: to Twin or not to Twin?

When it comes to extrusion, then diverse machines are readily available for it. One of them is conical twin-screw extruder PVC. This machine is automatic and can easily handle the PVC extrusion task. The price is directly proportional to its highlights and features. It is an imperative part of the extrusion line.

Extrusion basics: To twin or not to twin?

Before you are going to set up a PVC pipe extrusion line, you have to know the basics of extrusion in a better way. Many people do not know the difference between twin-screw extrusion and single screw extrusion. In case, you are one of them then you will be glad to know that we are going to explain it now. 

Firstly, you need to know that extruders are present in diverse types. Each one has a different length, diameter, power limitations, speed, and design. If you are going to purchase an extruder then you must know your requirements. When you will be clear about your needs and wants then you will be able to make the right choice. However, you need to choose according to the product you have to make. In case, you will know which product you have to make and how much will be the production rate then you can easily make the decision. In diverse cases, the requirement of the downstream machine is as imperative as the extruder itself.

Secondly, you need to ask yourself which brand produces the best extruders. Several brands are present that are offering extruders in various types. You need to choose the one who provides guarantee and support services. Some suppliers can help you with this yet you need to spend some time in finding the best machine. Furthermore, you have to consider the PVC extruder machine price. If the price of the machine comes under your budget then it is good to buy it.

The single-screw extruders are presently more than the twin-screw extruders. Nevertheless, the twins are useful for two markets which include compounding and inflexible PVC. One of these examples is conical twin-screw extruder PVC. This extruder is excellent to produce rigid PVC. Keep in mind that the twins for one task are dissimilar from the other. The PVC lines feature screws of one piece. These screws are capable enough for interconnect in the container of eight-figure. 

Today, many PVC twins have screws in parallel form like the conical twin-screw extruder PVC. The first conical extruder was introduced in 1970 to solve the thrust bearing issue. In this extruder, the tubes deviate in the back which allows the big bearing to take the thrust diffident.

Final Words

When you are going to choose the twin then you need to choose between the used and new machines. The used extruders can save you a lot of cash and time, yet they need excellent maintenance regularly and good inspection team. On the other hand, new machines require proper installation and maintenance. You need to hire a special team that can take care of this machine. If this team handles the machine proficiently then your PVC pipe extrusion line will work in the long run.
