Primasil provides the flexibility of moulding low volume single cavity prototype products through to high volume multi-cavity production runs.
Liquid silicone is typically supplied in two parts with one of the parts containing the platinum catalyst. These are automatically mixed with any colours and ingredients which may be required. The mixing produces a very homogeneous material that leads to consistency from part to part.
The material is pumped into an appropriate injection press and cured by heat in very rapid cycles, with parts normally automatically de-moulded directly into a box. This process leads to minimal waste which eliminates trimming operations and reduces material cost significantly. These savings become even more apparant for high volume jobs and for components demanding high precision.
Bespoke steel tooling is essential, and our development team works extremely closely with specialist tool makers to ensure we achieve the optimum tooling solution using the latest CAD technology. The combination of a very small number of specialist toolmakers and the precision required, results in high tool costs. This is offset by the very low cycle times that can be achieved, coupled with excellent quality and high volumes.
