DFocus Rapid Prototype

Over Mould Casting

Over-mould casting bonds a soft elastomer (such as silicone rubber or flexible polyurethane) onto a rigid substrate, creating multi-material parts in a single workflow. Perfect for grips, seals, buttons, and ergonomic housings.

Over Mould Casting

Over-moulding bonds two different materials together — typically a rigid ABS-like core with a soft-touch TPE or silicone outer layer. This creates ergonomic grips, waterproof seals, vibration dampening, and multi-colour parts all in one step.

Using vacuum-cast silicone molds, we can deliver over-moulded prototypes in 5-7 days without expensive injection mold tooling. Ideal for consumer electronics, power tools, medical devices, and any product requiring a soft-touch interface.
