Extrusion

Definition

Extrusion is the process of squeezing a material through a shaped orifice (die) to produce a linear element with the desired cross-section. The element produced by this process is also referred to as an extrusion.

Purpose

The purpose of Extrusion is to create continuous lengths of material with consistent cross-sections, allowing for efficient and precise manufacturing of structural and decorative components used in various industries.

Examples of Use

• Plastic Piping: Producing continuous lengths of plastic pipes for plumbing and irrigation.
• Aluminum Profiles: Creating profiles for window frames, door frames, and structural supports.
• Rubber Seals: Manufacturing rubber extrusions for automotive and industrial sealing applications.

Related Terms

• Extruded: Referring to materials that have been formed through the extrusion process.
• Die: The tool used in extrusion to shape the material as it is forced through.
• Continuous Production: A manufacturing process that produces long, continuous pieces without interruption.

Notes

• The properties of the material and the design of the die are critical factors in the quality and consistency of the extrusion.
• Extrusion allows for the production of complex shapes that would be difficult or impossible to achieve with other manufacturing methods.
