Twin screw segments

Screw elements are the main working parts for twin screw extruder which determined the quality and output of plastic products.With high quality,the screw elements assure plastic molecular mixing,cutting,spreading as well as reacting among themselves etc.Extremely high self cleaning performance assure the high quality of the whole production line,for this,our company combiend our experience for years,the merits about foreign countries and the customer’s use,then take them into action,designed all kinds of suitable processing screw element with reasonable parameters,high self cleaning performance,wear resistance,corrosion-resistance.

When it comes to material selection for twin screw threaded elements, here are some more detailed options, depending on the application and requirements:

• High-speed steel (High-Speed Steel, HSS): Common HSS includes W6Mo5Cr4V2 (M2), W6Mo5Cr4V2Co5 (M35), etc. These materials have excellent machinability and wear resistance and perform well in general extrusion processing.
• Tool Steel: Commonly used tool steels include SKD61, SKD11, etc. These materials have high hardness, high wear resistance and some corrosion resistance, and are suitable for processing thermoplastic elastomers, high temperature plastics or corrosive materials.
• Stainless Steel (Stainless Steel): Stainless steel usually includes grades 304 and 316. Stainless steel has good corrosion resistance and high temperature resistance, and is suitable for processing plastics or high temperature plastics that require corrosion resistance.
• Special Alloy Steel: Special alloy steel can be selected for extrusion processing in harsh environments such as high temperature, high pressure, and high wear. These materials have excellent heat resistance, corrosion resistance and wear resistance, such as alloy steel, nickel-based alloys, etc.

We can satisfy your different material needs

We design and manufacture screw and kneading segments for co-rotating twin screw extruders ranging from 15.6 mm to 350 mm and over. Our manufacturing specializes in segmented screws for twin screw extruders and is optimized for flexible order handling.

Twin-screw extruder is a kind of equipment commonly used in plastic processing and plastic product production. It is formed by two screws rotating side by side. Through the rotation of the screws and the mutual pushing between the screws, the solid or molten plastic material is extruded and processed to form the desired product shape.
Twin-screw extruders have the following advantages over single-screw extruders:
Better mixing effect: Since two screws rotate at the same time, the twin-screw extruder is more thorough in mixing, plasticizing and homogenizing plastic materials, making the quality of the product more uniform.
Higher production capacity: The twin-screw extruder can process more materials in the same time, so the production capacity is higher, which is suitable for mass production.
Applicable to a wide range of materials: The twin-screw extruder is suitable for processing different types of plastic materials, including heat-sensitive materials and high-viscosity materials.
Twin-screw extruders are widely used in the plastic products industry, including the production of plastic pipes, plastic films, plastic profiles, plastic granules, etc. It can also be used for extrusion processing in rubber, chemical, food processing and other fields.
