Injection compression moulds


Injection compression moulding consists of two distinct steps to shape the part: in the first step, the molten material is injected with the mould open, while in the second, the platens of the press move closer together and contribute to the final distribution in the mould, compaction, and compensation of mass shrinkage.

Thanks to the combination of the advantages of these two steps, this technology allows elements to be formed with improved characteristics. In fact, the second step allows the previously injected melt to be plasticised at a lower pressure than standard, relaxing the plastic fibres through compression as it brings them into their final position.

Reducing the stress to which the plastic is subjected makes it possible to increase the strength characteristics of the components, with a decrease in weight for the same strength or increased strength for the same weight.

Injection compression moulding is an effective technique for producing thin parts with a high surface quality, such as in optical applications, displays and lighting components.
