Cold Moulding

Transform your production process with our advanced cold moulding. Our master technicians create high-definition RTV silicone moulds that deliver exceptional detail reproduction and production efficiency for jewellery manufacturers.

Master cold moulding for premium jewellery replication

Our premium RTV (room-temperature vulcanising) silicone moulding process creates flexible, durable moulds that can be used repeatedly without quality degradation:

  • Extended mould lifespan, with capacity for multiple wax injections
  • Precise detail capture down to microscopic textures and patterns
  • Cost-effective production for both small-batch and high-volume manufacturing
  • Consistent wax pattern quality across your entire production run

Versatile master pattern compatibility

Our process accommodates virtually any master pattern, which means you are not constrained in how you originate a design.

  • Metal originals: gold, silver, brass, or other metals
  • 3D-printed prototypes from a range of materials and technologies
  • Existing jewellery pieces that need reproduction or modification
  • Complex designs with undercuts and intricate detail
