Conical twin screws are widely used in the plastics industry for extrusion processes. These screws have a unique geometry, which consists of two parallel, tapered screws that rotate in opposite directions within a barrel.
The conical twin screw extruder is versatile and can be used in a variety of applications, such as:
PVC Pipe Extrusion: Conical twin screw extruders are commonly used to produce PVC pipes. These extruders have high output rates and can handle a wide range of PVC formulations.
Profile Extrusion: Conical twin screw extruders are also used for profile extrusion. They can produce a variety of profiles such as window frames, decking, and fencing.
Sheet Extrusion: Conical twin screw extruders can be used to produce sheet products such as PVC and PP sheets.
Compounding: Conical twin screw extruders are used in the compounding process to mix and homogenize raw materials such as PVC, PE, and PP. They can be used for both dry blending and melt blending.
Recycling: Conical twin screw extruders can be used for recycling applications. They can process a wide range of materials, including post-consumer waste, and produce high-quality recycled products.
Overall, conical twin screw extruders offer many advantages such as high output rates, better mixing, and excellent melt quality, making them a popular choice for various applications in the plastics industry.
