Silicone Molds for Production-Like Parts
A master pattern is used to make a silicone mold, then polyurethane resin is cast under vacuum. The result looks and behaves like the final molded part — without the cost of steel tooling.
Best for market testing, bridge volumes and design validation
Use urethane casting when you need 10–200 parts with the right colour, texture, hardness and assembly fit. It is ideal before committing to injection molding tooling.
- Looks-like and works-like prototypes
- Bridge production before hard tooling
- Colour matching, texture and soft-touch
- Inserts, overmolded features and assembly
Why Choose Us for Urethane Casting
Low tooling cost
Silicone molds avoid steel tooling, so low volumes become economically viable.
Fast turnaround
Silicone molds in 2–3 days; cast parts from 7 days, including finishing.
Production-like materials
Rigid, flexible, rubber-like and transparent PU systems from 25A to 90A Shore.
Finish & colour
Colour matching, texture, painting, laser marking and assembly under one roof.
How Urethane Casting Works
Master pattern
Your CAD or a 3D printed master is finished to the required surface and tolerance.
Silicone mold
A vacuum-cast silicone mold captures undercuts, texture and fine detail.
Cast the part
PU resin is poured under vacuum, then cured to the specified hardness and colour.
Finish & inspect
Deflashing, painting, texture, inserts and dimensional checks before shipment.
Material Options
Choose the hardness, look and feel that match your production intent.
ABS-like & PC-like
Stiff housings, covers and structural parts with a smooth or textured surface.
Shore 25A–90A
Grips, seals, gaskets and soft-touch parts with rubber-like recovery.
Clear & tinted
Light guides, lenses and transparent housings with polishing options.
Pantone / RAL matching
Colour matching in the resin or paint, with gloss, matte and soft-touch finishes.
Metal & hardware
Threaded inserts, magnets, metal reinforcements and overmolded features.
Paint, texture, laser
Primer, paint, texture, laser marking, pad printing and assembly.

Industries We Serve
Questions About Urethane Casting
How many parts can one silicone mold make?
Typically 10–200 parts per mold, depending on geometry, resin and demolding care. We confirm the expected mold life during DFM.
How fast is urethane casting?
Silicone molds take 2–3 days; cast parts are typically ready in 7 days, including finishing.
Can you match my production colour and texture?
Yes. We match Pantone/RAL colours, gloss or matte levels, textures and soft-touch finishes against an approved sample.
What is the difference from injection molding?
Urethane casting uses a silicone mold and PU resin, so tooling is much cheaper and faster, but part volume and material choice are more limited.
Do you sign an NDA?
Yes. Tell us before sending files and we will issue a mutual NDA.
