Commitment to sustainability coupled with quality to reduce emissions by 40%

Rosti sits at the centre of the supply chain and has a duty and an opportunity to make a positive environmental impact on the plastics industry. After more than one year investigating the Roctool technology, Rosti installed our first Roctool technology system in the China manufacturing site. The adoption will allow up to 40% CO² reduction due to the patented heating and cooling processes.

Roctool’s patented technology consists of quickly heating the tool surface by induction and cooling the tool also rapidly with water cooling channels.  With this new technology and capability, Rosti can offer key advantages to its customers such as aesthetic, design and process improvements whilst also meeting commitments to reduce the carbon emissions at the plant.

The rapid induction heating from Roctool, adapted to injection moulding, will increase our capabilities to deliver a breakthrough in sustainability solutions” says Pat Williams, Senior Vice President Asia “Rosti is already working on new customer applications where the Roctool process will be fully exploited as part of our 6R Sustainability Commitment.

One of the key advantages of the Roctool system is the proven ability to mould plastic parts with no surface defects and as a result avoid secondary operations which are CO² consuming. Avoiding secondary operation and still offering a premium surface finish is becoming a trend in the industry in search of sustainability solutions.

For decades, Rosti has provided industry-leading injection moulding services, and continues to develop and invest in cutting-edge technologies. Rosti capabilities include in-mould labelling and decoration, multi-k injection moulding, liquid silicone rubber, injection blow moulding, clean room production and more.

Recent studies show a comparison between a painted part moulded conventionally and a Roctool part without any secondary operation with the CO² savings attained at more than 40%. This CO² reduction becomes even more dramatic when combining Roctool technology for top surface quality and recycled resins: in this case the CO² reduction can reach more than 80%. Roctool technology can be used for many plastic applications including beauty packaging, consumer products, appliances, automotive, industrial.
