What is Extrusion?

Extrusion is a manufacturing process that is used to produce objects of fixed cross-sectional profiles. In this process, the metal or plastic is forced into a closed cavity using a hydraulic or a mechanical press. In this process, the machines produce shear and compressive forces to form the final shape—the die in which the material block is contained, coated with a wear-resistant material.

What is Extrusion?
Plastic Extrusion

Plastic Extrusion

In plastic extrusion, the machine produces objects by shaping the liquid materials leveraging a rigid frame called mould. While moulding the plastic material block, liquid polymer like polypropylene is kept into an empty mould so the polymer can take shape. Standard plastic extrusion processes are sheet (Film) extrusion, blow film extrusion, and over jacketing extrusion.
Popular materials used in the polystyrene extrusion process are high impact polystyrene (HIPS), PVC, polyethylene, polypropylene, and ABS. Widely-used plastic extrusion applications are brush products, refrigeration, HVAC, cable and wire.

Metal Extrusion

In metal extrusion, a cylindrical billet inside the closed cavity is forced against a die of the fixed cross-section. These fixed cross-section profile’s extruded objects are known as extrudes. Commonly-used metal is copper, aluminium, steel, and magnesium. Metal extrusion produces parts with an excellent surface finish. With metal extrusion, engineers can achieve a minimum wall thickness of up to 1mm.

Types of Extrusion Processes

KARV automation offers a complete range of extrusion processes to help you with all custom requirements. Here are some of the commonly-used extrusion processes:

Cold Extrusion

In cold plastic or metal extrusion, the material blocks are pushed through a die at or below room temperature. In this manufacturing process, the material blocks in the form of a slug and then poured into the cast’s feeder. High pressure at the feeder combines the material parts to form the final product.

Hot Extrusion

In a hot plastic or aluminium extrusion process, the metal goes through heating at a higher temperature, and it’s force-pushed into the die. The high temperature can go from around 340°C to 700°C. This extrusion process happens above the recrystallization temperature.

Friction Extrusion

In this process, the machine generates higher friction when the metal slug and the design die rotate at high-speed to create friction. The generated heat helps the metal to pass quickly through the design die of the custom shape.

Micro Extrusion

This modern process creates micro-sized objects with highly-intricate geometries. In the micro extrusion process, the cast’s cross-section area is 1 mm, and it helps develop micro-objects at a higher speed. The micro extrusion process is ideal for manufacturing small-sized mechanical spare parts.

Applications of Extrusion

Extrusion is a widely-used manufacturing technique, and multiple industries leverage its strong potential to boost their operations. Some of the industrial applications of extrusion are:

  • The extrusion process widely leverages in manufacturing and hollow pipes and tubes
  • It is an ideal process for manufacturing windows, doors, frames
  • Extrusion is suitable for performing complex structural work
  • Extrusion is used to produce various electric systems
  • It is used to create high-quality structures for machine guarding
