EXJECTION®

EXJECTION® – injection moulding in a new dimension

The first-ever EXJECTION® system combines the advantages of both extrusion and injection moulding technologies! With this new technology, long profiles and bars can, for the first time, be manufactured on a small injection moulding machine.

What used to be impossible can now be done thanks to EXJECTION®: manufacturing thin-walled profiles and bars with lengths up to 3 meters – on a small injection moulding machine with a clamping force of 500 to 1500 kN. The economic advantages are obvious: reduced equipment investment of up to 50 percent, and significantly lower manufacturing costs.

The process

Mould in Motion
In the EXJECTION® process, the cavity that is moulded in a slide is moved past the nozzle at the same time as the injection movement. The fluidity of the plastic melt needs only be sufficient to fill the profile cross-section. This permits the use of macromolecular, viscous types of plastic that are characterised by a very good profile of mechanical properties. The plastic part is injected into a mostly closed cavity. This mould concept opens new design possibilities, such as reinforcing ribs, screw bosses and end covers, as well as high-quality structured surfaces.

Broad range of applications
There is a wide range of applications for the EXJECTION® procedure. It starts in the construction and furniture industry, goes through the areas of automobiles and air transport and lands in the packaging and white goods industry. In short, everywhere long plastic parts are currently used.
