Injection molder and contract manufacturer Rosti Group has installed the first Roctool heating and cooling system at its facility in China. This will allow the molder to reduce its CO2 emissions by as much as 40%. Rosti said that it sits at the center of the supply chain and has a duty and an opportunity to make a positive environmental impact on the plastics industry.
Roctool's patented technology consists of quickly heating the tool surface by induction and rapidly cooling the tool via water channels. With this technology, Rosti said that it can offer key advantages to its customers, such as aesthetic, design, and process improvements, while meeting commitments to reduce carbon emissions at the plant.
“The rapid induction heating from Roctool, adapted to injection molding will increase our capabilities to deliver a breakthrough in sustainability solutions," said 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 mold plastic parts with no surface defects, avoiding secondary operations that have an environmental impact.
Rosti cited a comparison between a conventionally molded painted part and a Roctool part that achieved a more than 40% reduction in CO2 emissions. The reduction becomes even more dramatic when Roctool technology is combined with recycled resins, according to Rosti, which can reduce CO2 emissions by more than 80%. Roctool technology can be used for many plastic applications, including beauty packaging, consumer products, appliances, automotive, and industrial.
Rosti is a global, technology-led plastic injection molding company and contract manufacturer serving some of the world's leading manufacturers in the packaging, consumer appliances, business machines, and medical sectors. Headquartered in Malmö, Sweden, the group has 3,200 existing employees across nine facilities in Europe and Asia. Capabilities include in-mold labeling and decoration, multi-k injection molding, liquid silicone rubber, injection blow molding, and cleanroom production.
