Rosti has a deep knowledge and experience in using an array of materials that comply with stringent sector and international regulatory and compliance standards.
Our team have developed an unrivalled understanding of the properties and applications of various plastics such as PEEK, polycarbonate, and polypropylene.
Collaborative Design Process
Rosti collaborates closely with our customers during the product development phase. This includes advising on material selection that balances performance, cost, manufacturability, and compliance. Our design for manufacturability (DFM) services help in optimising the product design to make it more efficient for injection moulding.
Innovation Centres play vital role in Material Selection
Rosti’s Innovation Centres focus on research and development (R&D) activities that include the study and testing of various materials to understand their properties, capabilities, and limitations. This research helps in identifying the most suitable materials for specific applications, considering factors like biocompatibility, strength, flexibility, and durability.
One of the key advantages of the Innovation Centres is the capability to rapidly prototype new products using different materials. This rapid prototyping enables practical, hands-on testing of materials in real-world applications, allowing for adjustments and optimisations before finalising the material selection for production.
This process and capability is continuously recognised as a key strength of our partnership with our global customers, thanks to 3 different R&D centres, Rosti bring not only fast delivery but also unity of prototyping services.
In addition to performance and compliance, Innovation Centres also consider the environmental impact in the material selection process. It is one very clear trend that, sustainability is a “must have” service, we have the ability to co-develop, test and validate bio-resins.
Ensuring Material Compliance and Safety
Rosti only use materials that have been certified as safe and appropriate for their intended use and application. We play a key supportive role in collaborating with our customers and their resin suppliers to double check not about technical feasibility, but also for safety/regulation consistency.
Rosti carefully selects and audits our material suppliers to ensure they meet high standards. Supplier audits and ongoing performance evaluations ensure that only high-quality and compliant materials are used in the manufacturing process based on customer target market entry regulatory requirements.
We collaborate with regulatory experts and consultants who specialise in regulations across different markets. This ensures that the materials and the final products are compliant with all relevant international regulations, such as FDA regulations in the U.S., the European Medical Device Regulation (MDR), and others.
Shifting to Sustainable Materials
Many businesses are now looking for ways to reduce their environmental impact, and one way to do this is to use sustainable materials in their products.
After analysing 100’s of materials in our Innovation Centres, we are able to support our customers to make fact based decisions when looking select environmentally friendly materials. We can provide advice on a wide ranging of material types including PCR and bio resins as well as alternatives such as wood based materials.
