Plastic Extruder Screw Element With HRC58 Vacuum Quenching

Plastic Extruder Screw Element with HRC58 Vacuum Quenching

Product Description

The Plastic Extruder Screw Element is designed for plastic extrusion applications that require consistent wear performance during long production cycles. The component reaches a target hardness of HRC58 through vacuum quenching.

Vacuum quenching provides a controlled heat-treatment environment with reduced exposure to oxidation during processing. This helps maintain a clean component surface and supports consistent hardness after heat treatment.

The hardened screw element can handle repeated contact with plastic materials and is suitable for extrusion processes where screw components experience continuous mechanical loading. Its final geometry can follow the customer's screw arrangement and equipment requirements.

CONLIN manufactures plastic extruder screw elements according to technical drawings, samples, OEM part numbers, or existing component dimensions.

Product Specifications

Vacuum Quenching

Vacuum quenching is an important part of the manufacturing process for this screw element. The controlled atmosphere helps limit oxidation and surface contamination during heat treatment.

After quenching, the element can achieve a target hardness of HRC58, depending on the selected material and heat-treatment specification. This hardness level provides a suitable balance between surface hardness and mechanical performance for many plastic extrusion applications.

Applications

The HRC58 screw element can be used in various plastic processing applications, including:

• Plastic extrusion
• Polymer compounding
• Engineering plastics
• Filled plastic processing
• Masterbatch production
• Thermoplastic processing
• Continuous extrusion
• General plastic material processing

For highly abrasive or corrosive formulations, CONLIN can recommend different material and surface-treatment options according to the actual processing conditions.

Custom Manufacturing

CONLIN can manufacture screw elements to match the customer's existing extrusion equipment.

Please provide the extruder model, screw drawing, shaft dimensions, sample, or OEM part number. We can use these details to determine the required element geometry, connection dimensions, material, and heat-treatment specification.
