Extrusion heads
Be it for the extrusion of profiles or flexible hoses or the sheathing of cables- we offer straight-through heads or cross heads for use with our extruders for the most varied applications.
In addition to our standard extruders, we develop and manufacture special dies or tools to your specifications.
Many years of experience and continuous further development enable us to offer dies or tools that are easy to clean and come with optimal flow channels.

Extrusion heads are specially designed devices that enable this extrusion process. They typically consist of a die or formthrough which the material is pressed, along with an extruder that feeds the material into the form or die.
In the case of rubber extrusion, it is pressed through a die or form to create continuous profiles such as pipes, profiles, or sheets. The extrusion tool determines the shape and size of the final product.
Extrusion tools must be precisely manufactured to ensure uniform material distribution and high-quality end products. Depending on the application and Material, they can have different shapes and features to meet the specific requirements of the extrusion process.
What requirements are placed on extrusion heads?
Dies and forms:
dies or form is the part of the extrusion tool through which the material is pressed to achieve the desired shape. Depending on the application, die can be round, rectangular, oval, or have other shapes. They are usually made from high-strength materials like as steel or carbide to minimize wear and deformation during the extrusion process.
Cooling and Temperature Control:
for many extrusion applications, controlling material temperature is crucial for final product quality. Extrusion tools may have integrated cooling channels or other mechanisms for temperature regulation to ensure that the material maintains the correct temperature throughout the extrusion process.
Pressure and Material Control:
To ensure uniform material distribution and precise shaping, extrusion tools must precisely control material flow and pressure. This can be achieved through specialized inlet and outlet openings, as well as pressure control systems that monitor and adjust material flow during the extrusion process.
Wear Resistance and Durability:
Since extrusion tools often face strong mechanical stresses and abrasive materials, they must be extremely wear-resistant and durable. This often requires high-quality materials and precise manufacturing techniques to ensure that the tools maintain high performance and precision even during long production runs.
Adaptability and Flexibility:
Some extrusion tools are designed to adapt to various production requirements. This can be achieved through the use of interchangeable inserts or by adjusting tool parameters to process different materials or product configurations.
Extrusion heads are crucial components in the manufacture of a wide range of products in various industries. Thanks to their precise design and manufacture, they make a significant contribution to the quality and efficiency of the extrusion process.
