Coulage surmoule

Surmoulage 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.

Coulage surmoule

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.

Comment préparer un RFQ exploitable

Surmoulage for two-material prototype validation

Surmoulage supports prototype parts that need a rigid insert with a softer grip, seal, cover, or touch surface before committing to production tooling.

Best-fit use

Soft-touch grips, handles, seals, wearable covers, protective corners, insert prototypes, and user-test assemblies.

Files to send

CAD for both materials, insert details, Shore hardness target, color reference, bonding area, quantity, and assembly purpose.

DFM checks

Undercuts, insert location, wall thickness, bonding surface, parting line, air traps, and expected prototype durability.

Acheteur warning

Prototype over-mould casting validates appearance and fit, but production overmolding still requires tooling and material review.

Comment préparer un RFQ exploitable

Before quoting, send the part purpose, CAD revision, material target, finish, tolerance-critical features, inspection expectations, packaging needs, and destination so engineering can price the correct route.

Ce dont les ingénieurs ont besoin pour examiner précisément

Une RFQ plus solide précise l’objectif fonctionnel, les cotes critiques, les exigences d’aspect, la quantité, les contraintes flexibles et les preuves d’inspection attendues avant expédition.
