Custom Silicone Prototype Development
RUUIPON supports prototype development for custom RTV silicone molds, HCR/HTV products, LSR components and overmolded assemblies.
The prototype route depends on what the final production process will be.
A prototype should prove the highest-risk requirements before production tooling or quantity is repeated.
What We Need

Send:
- drawing/CAD/sample/photos
- what you need to receive
- application
- critical dimensions/function
- prototype quantity
- expected production quantity
- target date
RTV Mold Prototype
Can validate:
- cavity geometry
- release
- weight/volume
- logo/detail
- support
- real casting process
Straightforward design + prototype may take about 3–5 days after required information is approved.
HCR/HTV / LSR Prototype
The route and timing depend on:
- production tool strategy
- material
- geometry
- quantity
- whether prototype tooling or production-intent tooling is used
Do not apply RTV timing/MOQ automatically.
Physical Sample / Reverse Engineering
For fit-critical projects, a real physical sample can be used as a development reference.
Approval Gate
Production does not start until the agreed prototype/design revision is approved.
Real Buyer Questions
Can I make only one prototype?
Yes, when the project route allows it.
Can I send a physical sample?
Yes.
Can you test-cast the mold before shipment?
Yes, when included in the agreed scope.
Does prototype approval lock production?
It locks the agreed revision/criteria; changes after approval are revisions.
