AGC mainly supplies aluminium extrusion parts, but we can also work with other materials such as rubber, plastic and steel. Our customers particularly value our low-cost tooling solutions and our extrusion-part finishing capabilities.

Extrusion process explained

Extrusion is carried out by pushing material through a fixed die in a high-pressure press. The result is an extruded bar with a cross-sectional profile that corresponds approximately to the negative of the die; complex shapes may require multiple dies.

The material is usually heated to around 400°C for aluminium before entering the press to facilitate shaping. Bars are typically extruded to lengths of up to 12 m, although longer or shorter lengths may be available for specific applications. Extruded parts have a constant cross-sectional shape along their entire length. Heat treatment may be carried out after extrusion to relieve stress in the profiles.

Profiles finishing

In addition to extrusion, several secondary operations can be performed:

– Cutting the profiles to the required length or width.

– Drilling and tapping holes along the profiles.

– Machining additional features that cannot be produced by extrusion alone.

– Deburring.

– Surface treatment, mainly anodising for aluminium.

Our extrusion solution, limits & possibilities

– For aluminium parts, our minimum order quantity ranges from 50 to 500 kg, depending on the part’s cross-sectional size. This corresponds to the break-even point for setting up a die on our presses.

– Extruded parts can weigh from a few grams to several kilograms. Please refer to our portfolio for examples of completed projects.

– We can achieve very good precision, up to ±0.02 mm, together with good dimensional stability over time.

– Parts have a smooth surface finish with a brushed effect that can be made more or less pronounced.
