Dive into the world of extrusion excellence with the Die Roller Extruder
The Die Roller Extruder is engineered to facilitate the extrusion of materials, making it an invaluable tool in various industries. It is especially ideal for applications that require precision and consistency in extruded materials.

The Die Roller Extruder features two horizontally placed rollers:

  1. Perforated Roller: This roller is responsible for creating perforations in the material.
  2. Knurling Roller: The knurling roller adds texture or specific patterns to the extruded material.

Here’s a step-by-step breakdown of how it works:

  1. Material is manually charged into the hopper.
  2. The hopper includes a drum and blade provision attached to a motor. This motor rotates and drives the material into the feeding hopper situated between the rollers.
  3. Due to the pressing nature of the rollers, the material is extruded through the perforations in the perforated roller.

This process results in precisely extruded material with the desired texture or pattern, making the Die Roller Extruder an indispensable tool for various applications.
