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.
- Multi-Material Bonding (Rigid + Soft)
- Shore A 30-90 Hardness Range
- No Tooling — Silicone Molds
Soft-touch grips, sealing, and multi-material prototypes.

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.

Over-mould casting for two-material prototype validation
Over-mould casting supports prototype parts that need a rigid insert with a softer grip, seal, cover, or touch surface before committing to production tooling.
Soft-touch grips, handles, seals, wearable covers, protective corners, insert prototypes, and user-test assemblies.
CAD for both materials, insert details, Shore hardness target, color reference, bonding area, quantity, and assembly purpose.
Undercuts, insert location, wall thickness, bonding surface, parting line, air traps, and expected prototype durability.
Prototype over-mould casting validates appearance and fit, but production overmolding still requires tooling and material review.
How DFocus uses this page
This page is part of the quote-preparation path. It helps a buyer move from a broad prototype idea to a practical manufacturing brief with process choice, material notes, tolerance expectations, surface finish requirements, inspection needs, packaging notes, and delivery assumptions.
What makes the RFQ stronger
A stronger RFQ explains what the part must prove, which dimensions matter, whether appearance or function is more important, how many pieces are needed, what is flexible, and what evidence the buyer expects before shipment.
