Made around your product
Your Shape. Your Logo. A Mold Built for Your Process.
Develop a custom mold for the product you want to make. We review the shape, cavity layout, casting material and release method together, from the first reference images through prototype approval.
Start with CAD, a sketch, measured photos or a sample. Include your dimensions and expected quantity so we can confirm the design and manufacturing scope.
What Are You Trying to Make?
01
A Flexible Mold for Casting Another Material
Use this route when the silicone mold will be filled with gummy, chocolate, resin, plaster, wax, soap, water, batter or another compatible casting material.
RUUIPON can review cavity geometry, release direction, mold structure, tray support, branding and production layout before production molds are made.
02
A Design or Prototype Before Production
You do not need perfect production CAD to start a discussion.
A sketch, sample, photo set or rough model can be enough for an initial DFM review. If new geometry must be created, the design scope and approval point should be defined before tooling begins.
03
A Food-Contact Mold
For gummy, chocolate, baking, ice and other food-contact projects, material selection and documentation need to match the actual use and destination market.
04
A Finished Silicone Product or Component
If the finished item itself is silicone, the project may require HCR/HTV compression molding, LSR injection molding or an overmolding route rather than an RTV casting mold.
Process selection depends on the part geometry, material, production volume, tolerances, inserts and intended assembly or use.
Manufacturing Routes We Can Review
01
RTV Silicone Mold Manufacturing
Flexible molds used to cast another material. Mold structure may be one-piece, split, cored or supported depending on the geometry and casting process.
02
HCR/HTV Compression Molding
For suitable finished silicone products and components produced in heated compression tooling.
03
LSR Injection Molding
For suitable liquid silicone rubber parts where geometry, repeat production and process requirements justify an injection-molding route.
04
Silicone Overmolding / Insert Molding
For projects where silicone must be integrated with a compatible insert or substrate.
Start From the Information You Already Have
A useful project review can start from any of the following:
- STEP/STP or other production CAD;
- STL or mesh geometry for sculptural parts;
- 2D drawings with key dimensions;
- a physical sample that can be measured;
- a sketch plus dimensions;
- clear photos and reference images when the design is still being defined.
If the project is confidential, tell us before sending the complete design so the NDA requirement can be addressed first.
What We Review Before Tooling
01
1. What You Need Made
Are you buying a flexible casting mold, a finished silicone part, metal tooling, or a silicone-overmolded assembly?
02
2. Geometry and Release
We review undercuts, deep features, fragile details, parting strategy, support and the real demolding or assembly path.
03
3. Material and Use
The material choice must fit the application, not a generic hardness or "food-grade" label.
04
4. Prototype Risk
The prototype should prove the features most likely to create cost or production problems: fit, cavity weight, logo detail, release, support, assembly or another project-specific requirement.
05
5. Production Handoff
Repeat production should reference the approved design revision and the acceptance criteria that matter to the project.
Applications
01
Food & Confectionery
Custom molds for gummy, chocolate, baking, ice, and candy. Material selection and supporting documentation are reviewed for the intended food-contact conditions. See food-safe silicone molds.
02
Resin, Craft & Decorative Casting
Flexible molds for resin, plaster, concrete and cement.
03
Custom Silicone Products
Finished molded silicone components and products where HCR/HTV, LSR or overmolding is the appropriate route.
What Good Evidence Looks Like
A supplier claim is more useful when it can be tied to the specific project.
Depending on what you are buying, useful evidence can include:
- the legal company identity used on the quotation;
- photos of the relevant production process;
- the approved drawing or sample revision;
- material identification and applicable test documentation;
- prototype photos or measurements against agreed critical features;
- packing and shipping details for the final order.
If a document or test report matters to your purchasing decision, request it by name and confirm what material or article it actually covers.
A Practical Development Sequence
01
Send the Requirement
Tell us what you need to receive, how it will be used, what files or samples you have, and the expected quantity.
02
DFM and Process Selection
We review your requirements and recommend a manufacturing process before tooling begins.
03
Design / Tooling Preparation
Where geometry must be created or revised, approve the relevant drawing or model before manufacturing proceeds.
04
Prototype and Real-Use Check
Test the requirement that matters: fit, casting, release, piece weight, logo, support, assembly or another critical function.
05
Production After Approval
Production follows the approved revision and project-specific commercial terms.

FAQ
Can you make custom silicone molds or parts from my design?
Send your design and explain whether you need a casting mold or a finished silicone item. RUUIPON reviews the geometry, intended use, quantity and material requirements to identify the suitable manufacturing route.
Do I need to provide a 3D CAD file, or can you design it for me?
A completed CAD file is not required for an initial review. Send a drawing, sketch, measured photos or sample details with the dimensions and intended use. If modeling is needed, we confirm the scope, fee, deliverables and approval steps before paid work starts.
How much does 3D / CAD design cost?
Simple 3D modeling is USD 50 when the agreed work falls within that scope. More complex reconstruction or substantial changes are quoted separately. The scope, deliverables and approval steps are confirmed before paid design work starts.
Can I get a sample or prototype before ordering production?
A prototype can be included in the development scope. We confirm what it needs to demonstrate, the applicable quantity and the schedule before work begins. Applicable custom RTV production starts at 20 molds per design.
What is your minimum order quantity (MOQ)?
Applicable custom RTV mold production starts at 20 molds per design. Prototype quantities and requirements for HCR/HTV, LSR or overmolding projects are confirmed separately.
How do you quote unit prices for different quantities?
Send the design, dimensions, casting material, cavity requirements and mold quantity. We review the design and production scope, then identify the applicable modeling, tooling, prototype, production and shipping costs in the quotation.
How much is mold / tooling, and who owns the mold?
Tooling costs depend on the design, master preparation, mold structure and any required support. CAD deliverables, ownership, master or tooling custody, and rights to reproduce the design should be confirmed in the written project agreement.
What is the typical lead time?
The schedule depends on the manufacturing route and the design, prototype and production work required. We confirm each stage and its approval requirements in the quotation. Buyer testing and shipping time are separate from the factory work schedule.
