The basic idea of Exjection is the production of "profile-like" components (strips) on an injection molding machine. Hence the characteristics of the component Exjection arise in which this technology brings in significant advance:
- with the possibility to create basically straight part a continuous linear connection
- Component length >> component cross-section
- End caps, snap hooks, ribs or similar elements formable
- Component is demouldable (usually normal to the component's longitudinal axis)
- (Visible) surfaces with 3D structures and / or functional elements
What materials are usable?
Since the method seen from the process here is very close to the conventional injection molding process, it is very easy and briefly summarized: Everything is processed in an injection molding machine, can generally be used also for the Exjection process. Three points should be noted:
- More viscous materials (extrusion grades) have a wider process window for Exjection on
- The well-known guidelines for component design naturally also apply to the process Exjection
- Material Type and component wall thickness determine the carriage speed and thus the cycle time
Previously successfully tested with the research form with EXJECTION® a wide range of materials. Examples are:
|FACTOR PP GF
Composite: WOOD + ABS
- A composite material made of wood and ABS (acrylonitrile butadiene styrene).
- Combines special properties of both materials
Composite: CFK + ASA
- A composite material made of CFK (carbon fibre reinforced plastic) and ASA (acrylonitrile styrene acrylate).
- Combines the strength and rigidity of CFK with the properties of ASA
Inmould: FOLIE + SAN
- A process in which a film is injected together with SAN (styrene acrylonitrile) in a mould.
- The film fuses with SAN and forms a decorative or functional layer on the component.
