Plastic injection moulding

With a history in precision plastic injection moulding dating back to 1944, Rosti produces products and components to many industry sectors, from business machines and medical goods to consumer products and packaging.

In addition to over-moulding, insert moulding, gas injection, multi-shot, high cavity and stack moulding, our core capability is plastic injection moulding for precision parts.


Specialised in products with a narrow tolerance

We specialise in products with a narrow tolerance and a very high cosmetic finish. This is complemented by unique techniques, such as in-mould labelling (IML). At our state-of-the-art production plants, we provide the optimum level of performance, flexibility and care at every stage, all the way to finished packaging and distribution.
