Screw Elements for Petrochemical Applications

Petrochemical processing often requires reliable extrusion components that can handle continuous production, demanding material formulations, and different operating conditions.
CONLIN provides screw elements for applications such as:

• Polymer Compounding

• Polyolefin Processing

• Engineering Plastics

• Plastic Masterbatch

• Filled Polymer Compounds

• Plastic Recycling

• Chemical Material Processing

• Twin Screw Pelletizing

The correct screw element design depends on the processed material, filler content, processing temperature, screw speed, torque, and required mixing performance.

Precision CNC Machined Screw Elements

CONLIN uses CNC machining to manufacture accurate screw profiles, internal splines, bores, and connection dimensions.
We can supply different types of twin screw extruder screw elements, including:

• Conveying Screw Elements

• Mixing Screw Elements

• Kneading Blocks

• Kneading Discs

• Reverse Screw Elements

• Transition Screw Elements

• Compression Elements

• Special Screw Elements

• Side Feeder Screw Elements

Each element type supports a different function inside the extrusion process. Conveying elements transport material, while mixing and kneading elements help distribute and disperse components.

Material Options

CONLIN selects screw element materials according to the actual processing conditions.
Available material options may include:

• 38CrMoAlA Nitriding Steel

• 41CrAlMo7 Nitriding Steel

• SKD11 Tool Steel

• W6Mo5Cr4V2 High-Speed Tool Steel

• Stainless Steel

• Powder Metallurgy Materials

• Custom Material Grades

Material options depend on the required wear resistance, corrosion resistance, temperature performance, mechanical load, and budget.
For abrasive or chemically aggressive applications, customers should confirm the processing material and operating conditions before selecting a screw element material.
