Custom Silicone Mold Services

RUUIPON supports custom silicone mold development, from project and design review to prototypes and production. Applicable custom RTV production starts from 20 molds per design. Other manufacturing routes are reviewed and quoted for the specific project.

Open the pour you are quoting: gummy, chocolate, baking, ice, soap, candle, wax melt, or resin.

1. Project & DFM Review

We first identify:

• what the supplier must deliver;
• how the item will be used;
• geometry/release risk;
• material requirements;
• production quantity;
• critical dimensions/appearance;
• required documents;
• prototype purpose.

This avoids quoting the wrong object or process.

2. CAD / Mold Design Support

Projects can begin from:

• STEP/STP;
• STL/mesh;
• 2D drawing;
• physical sample;
• sketch;
• photos/reference images.

Where geometry must be created or corrected, define the design scope and approval file before tooling begins.

3. RTV Silicone Mold Development

For projects where the delivered silicone item is a flexible mold used to cast another material, RUUIPON can review:

• one-piece molds;
• slit/split molds;
• plugs/cores;
• support shells;
• multi-cavity trays;
• master/prototype route;
• production reproduction.

Applications can include food, resin, plaster, wax, soap and other compatible casting materials.

The exact structure follows the geometry and casting process.

4. HCR/HTV Compression Molding

For suitable finished silicone products, RUUIPON can review:

• compression-molded parts;
• product/tool DFM;
• metal tooling;
• material/hardness;
• color;
• repeat production.

Tooling, unit price and lead time for compression-molded parts remain project-specific.

5. LSR Injection Molding

For suitable LSR products, project review can include:

• product geometry;
• LSR material requirement;
• tooling route;
• gates/parting/ejection considerations;
• production quantity;
• inspection requirements.

6. Silicone Overmolding / Insert Molding

Where silicone must be integrated with another component, the DFM should address:

• insert/substrate;
• mechanical retention;
• interface geometry;
• molding process;
• material compatibility/bonding requirement;
• dimensional relationship;
• functional test.

Send the real insert or its locked CAD where fit is critical.

7. Prototype Validation

The prototype should answer a defined question.

Examples:

• Does the mold release the real casting?
• Does the gummy/chocolate hit target weight?
• Does a silicone component fit the mating part?
• Does a logo remain readable?
• Does a tray stay practical while filled?
• Does an insert remain retained?

A prototype that only “looks correct” may not prove production suitability.

8. Production Approval

Before repeat production, define the production reference:

• approved CAD/drawing revision;
• approved physical sample where relevant;
• material;
• color;
• critical dimensions;
• logo/artwork;
• functional requirement;
• documentation;
• packaging.

Changes after approval should be controlled as revisions.

Frequently Asked Questions

Does RUUIPON only make RTV molds?

No. RUUIPON supports RTV silicone molds, HCR/HTV compression molding and tooling, LSR injection molding, silicone overmolding and finished silicone-product projects where the project fits the process.

Can we start from photos or a physical sample?

Yes. Fit-sensitive or dimension-critical work may still require the real sample or locked CAD before tooling.

Is the same MOQ used for RTV, HCR/HTV and LSR?

No. RTV casting molds are MOQ 20 per design. HCR/HTV and LSR are a separate quote. Tooling, unit price, and lead time stay project-specific.

Can we sign an NDA before sending sensitive files?

State the confidentiality requirement before full disclosure so the NDA path can be addressed first.

What information is needed for a quotation?

An initial response and a confirmed quotation are different steps. A quotation depends on the drawings, quantity and technical requirements available for review. If information is missing, we will identify what is needed to complete the assessment.
