DIN Standard High Wear Resistance Twin Screw Extruder Segments & Screw Elements

Product Description

DIN Standard High Wear Resistance Twin Screw Extruder Segments

CONLIN manufactures high wear resistance twin screw extruder segments and screw elements for demanding plastic processing applications. Our screw elements use carefully selected alloy and tool steels to provide reliable performance under high-load and abrasive extrusion conditions.

These modular twin screw extruder screw elements install on splined shafts and form different functional sections of the screw configuration. Depending on the design, they can convey, mix, knead, disperse, compress, or control material flow inside the extruder.

Product Specifications

High Wear Resistance

CONLIN designs these screw elements for applications where standard screw segments may experience rapid abrasive wear.

Typical abrasive materials include:

• Glass fiber reinforced plastics
• Mineral-filled compounds
• Calcium carbonate filled plastics
• Talc-filled compounds
• Engineering plastics
• Recycling materials
• High-filler masterbatch

Abrasive fillers can accelerate screw element wear during continuous extrusion. Therefore, material selection, surface hardness, screw geometry, and machining accuracy all affect service life.

Precision CNC Machining

CONLIN uses CNC precision machining to produce accurate screw profiles, outer diameters, internal splines, and connection dimensions.

We manufacture different types of screw elements, including:

• Conveying Screw Elements
• Mixing Screw Elements
• Kneading Blocks
• Kneading Discs
• Reverse Elements
• Compression Elements
• Transition Elements
• Special Screw Segments

Different element geometries create different conveying and mixing effects. For example, conveying elements primarily transport material, while kneading elements provide controlled shear and mixing.

DIN Standard Manufacturing

CONLIN can manufacture screw segments according to DIN, GB, customer drawings, samples, and specified technical requirements.

We can customize:

• Outer Diameter
• Element Length
• Pitch
• Flight Profile
• Kneading Angle
• Internal Spline
• Bore Size
• Material
• Heat Treatment
• Surface Treatment

This makes the screw elements suitable for both OEM replacement and aftermarket applications.

Twin Screw Extruder Applications

CONLIN screw elements support a wide range of extrusion processes, including:

• Plastic Compounding
• Engineering Plastics
• Glass Fiber Reinforced Plastics
• Masterbatch Production
• Mineral-Filled Compounds
• Plastic Recycling
• Polymer Processing
• Twin Screw Pelletizing

The correct screw element configuration depends on the processed material, filler content, screw speed, temperature, required shear level, and production requirements.
