Roctool Beauty Solutions is enhancing its offer with a series of new tests. Indeed, during the last semester, Roctool has built partnerships and relationships with brands as well as certain manufacturers to assess the advantages of its ultra-fast heating and cooling technology of plastic injection moulds and tools.
Roctool thus accelerated its work on material analysis, injection trials, comparisons, data archives, etc. The completion of this applied research phase should allow the company to anticipate on current projects, with eco-responsibility always in sight.
The elimination of paint, one of the main advantages of the technology, adds economic arguments to the environmental benefits. And the use of recycled, bio based and biodegradable resins would contribute to further reduce the environmental footprint of plastic injection. However, each of these new resins requires Roctool doing extensive trials and testing before and during each specific development.
Conclusive trials on PCR PET & PP
In order to satisfy the double priority for brands, both aesthetic and environmental, Roctool focuses its efforts on testing materials and their injection behaviour.
The latest studies have focused on PCR PP, PCR ABS and PCR PET, they compared conventional injected parts with Roctool technology. For instance, they showed that PCR PET resulting from the recycling of bottles is suitable for good quality injection. Where the Roctool technology is used, plastic parts present a surface appearance without defects or weld lines. Whether it is a matt or glossy finish, the replication of the mould is optimal and directly challenges the equivalent finishes obtained by painting.
Thin walls and lower pression
Roctool is also making progress in assessing the advantages for producing thin-walled parts or reducing pressure during moulding.
For instance, for some PCR materials, the Roctool injection technology allows to fill 100% of a plastic part at a temperature of 110°C while, at an equal pressure and a temperature of 30°C conventional moulding only allows to reach a filling rate of 70%. Reaching a 100% filling rate with conventional moulding would require such pressures that “it would make the manufacturing process difficult,” said Roctool.
“The biodegradable and bio based resins currently being studied promise convincing results, both in terms of surface quality obtained and process stability,” added Roctool in a release.
