INJECTION COMPRESSION

Injection compression moulding is particularly useful for producing parts with complex geometries and thin walls, as it can help to maintain consistency and reduce the likelihood of defects. At Axxicon it is often used for the production of high-precision microfluidic consumables or thin-walled products or optical parts.

But please also take in consideration that injection compression can be more complex and time-consuming than conventional injection moulding, as it requires additional equipment and process control.

Specialist in Injection Compression

At Axxicon we believe Injection compression provides positive technical and economical benefits. It improves surface appearance, reduces fibre degradation during injection and reduces the sensitivity of the moulded part to warping. In addition it improves mechanical properties, reduces mould wear, and generally shortens cycle time. With thin-walled products, injection compression tends to further reduce the necessary injection pressure, consequently, to further increase the possible flow-distance/ wall-thickness ratios.

Regarding our polymer optic process, Faster injection into a open mould, the possibility of overpacking – in order to control shrinkage right from the start – as well as the very uniform and long-action holding pressure combine to reduce internal stresses in the moulded part, and improve its optical properties such as light defraction.

For finely textured surfaces, Injection compression moulding ensures exact and uniform duplication of micro textures on the moulded part surface – especially at the end of the flow path. It facilitates combining different textures and improves the degree of reproduction.
