From Aluminum Slugs to Impact extruded Parts

Slugs

The raw material used in the impact-extrusion process is the slug, which has a uniform volume determined by the required material. Slugs are soft-annealed when delivered.

Impact Extrusion

Knuckle-joint and hydraulic presses with ram forces of between 20 and 1.400 tons and speeds of 30 and 150 parts per minute are used to produce parts with lengths of up to 420 mm and outer diameters of up to 170 mm.

Heat Treatment

Heat treatment of suitable aluminum alloys can double their original strength and hardness (up to 550 N/mm2).

Heat treatment

To adjust the mechanical characteristics of the extruded part according to specification, heat treatment can be applied to suitable alloys. Thereby material strength and hardness can be up to doubled, an important aspect when designing parts for light but rigid constructions.

Machining

After the impact-extruded parts are processed on modern CNC lathes, milling machines and machining centers, they satisfy the most exact requirements imaginable with regard to precision and surface quality.

Degreasing

The parts are cleaned and degreased in aqueous washing machines. Test pens verify the surface tension for the purpose of checking the surface’s cleanliness.

Automated assembly

Numerous assembly processes are automated.

Quality assurance

Quality assurance already starts in the line and is also automated.

Packaging

The most modern technical aids available are used for packaging and preparing everything for shipping.
