Expertise in Tooling Design and Process Engineering
We believe the two key parameters to a successful product are expertise in tooling design and process engineering capabilities.
Tooling Design
Our hundreds of combined years of experience in tooling design and expertise in simulation include being rated in the top 10% in the world for mould-flow expertise. This level of expertise allows us to get your tooling design right the first time, at speed, utilizing the capabilities at our global innovation centre.
Process Engineering
Multi-Shot Injection Moulding involves the simultaneous use of two different materials, two temperatures, and two different pressures. Such complexity demands a different level of process engineering capability. This is where Rosti shines.
With years of experience and continuous refinement, we understand the intricacies involved in controlling a complex system to achieve the highest quality results.
To maintain our high standards, we conduct an annual benchmark assessment. This assessment helps ensure that our engineers are up-to-date with the latest techniques and technologies, ensuring that your project benefits from the most advanced process engineering capabilities available.
