Flexible Gaskets & Castings

Precision-engineered flexible cast components and bespoke silicone gaskets, built to your exact specification.

CNC machined mould and silicone spinal disc prototype

‍

We cast flexible gaskets and seals in RTV silicone and polyurethane elastomer, using moulds we make in-house: 3D printed, or CNC machined from model board. It suits prototypes and small production runs, and lets you test the seal on the real part before you commit to tooling.

Moulding Methods
‍
- Compression Moulding: A fast-curing silicone is placed into both halves of a 3D-printed mould, which is then clamped together, simulating mass production for prototyping.
‍
- Gravity/Injection Filled Moulding: A two-part mould is used where liquid silicone is injected into a channel, filling the cavity from the bottom up and allowing air to escape through vents.
‍
- Open-Face Mould: This method is suitable for simpler, one-sided designs, but it may lead to a non-level gasket with a meniscus edge.

“The quality of their work, attention to detail, level of service, as well as their ability to keep pace with the rapidly evolving technologies in this space, has continued to prove invaluable. A particular strength is being able to work alongside their modelmakers whilst exploring and developing designs, finding ingenious ways to create looks like and works like models as well as producing high quality presentation models that are often better looking than the final moulded product!”
