General information about double screw
The double screw is one of the key components that is used in the extruder, it is the specialized screw element with the special thread.
Material: Extrusion double screws are made of special high-quality steels or alloys that provide high-wearing feature and resistance to high temperatures.
The size and design of the double screws can vary significantly depending on the specific requirements of the process. The main parameters include diameter, thread, thread angle and number of zones (plasticization zones, mixing zones and others).
The usage of extrusion double screws: Extrusion double screws are used in the wide range of industries, including the production of film, pipes, profiles, cable sheaths, plastic packaging and many other products. They play a major role in ensuring the quality and efficiency of extrusion processes.
Correct use: The equipment is part of the extrusion line. The double screw is the main unit of the extruder. The screw rotates inside the heated cylinder, plasticizing PVC granules into the common mix for further application to the copper or aluminum core. To increase productivity and accuracy of temperature maintenance according to the technology, the screw design has internal cooling system.
Extrusion double screw:
Extrusion is a widely used process in industry that allows to create different plastic products, ranging from pipes and profiles to films and cable sheaths. The extrusion line is at the main equipment of this process, and one of its key components is the extrusion double screw
What is the extrusion double screw? The extrusion double screw is the specialized screw element with the thread, that rotating inside a cylinder, which is installed and used in the extruder.
Main functions of the extrusion double screw: The double screw takes the raw material at one end and pushes it towards the plasticization zone. Here, the solid granules are heated up and melted, forming the plastic mass.
The double screw ensures uniform mixing of various components of raw materials, PVC plastic, polyethylene, polypropylene, extruded fluoropolymer, rubber mixtures and some others. He also controls the dosing of these components to ensure the required product characteristics.
Q&A for extrusion screw:
Extrusion screws are specialized equipment components, that used in extrusion manufacturing for processing and shaping materials such as plastic and rubber.
Extrusion screws can process a wide range of materials, including plastics, rubber, polymers and metals, depending on their design and configuration.
Extrusion screws undergo nitriding, quenching, hardening and polishing processes, which gives them high hardness and long service life.
Extrusion screws have different diameters and lengths depending on the production process. Contact with Habsans specialists to select tool's individual parameters.
