Injection blow moulding

Expanding the possibilities thanks to injection blow moulding

Rosti’s continual investment in innovative technology has enabled us to provide our customers with increased product performance and with cost efficiency using injection blow moulding that has been developed in house.

New technology offers competitive advantages

Rosti has pioneered the mass-production of glasslike, thick-walled transparent plastic, used in applications such as lighting products and reusable drinking water bottles. Through the controlled blowing of partially hardened plastic while in the mould, we can manufacture highly aesthetic parts of any colour and/or degree of transparency.

Working in partnership with our customers, we focus on innovative, sustainable production processes that offer competitive advantages.
