Silicone Mold & Product Manufacturing Capabilities

Different silicone projects require different manufacturing routes.

RUUIPON supports custom silicone development across:

RTV silicone mold manufacturing;
HCR/HTV compression molding;
HCR/HTV tooling;
LSR injection molding;
silicone overmolding / insert molding;
custom silicone-product production;
DFM, CAD/design and prototype support.

The correct process is selected from the object, geometry, material, quantity and production requirement.

Send Your Project for Process Review

RTV Silicone Mold Manufacturing

Use this route when the silicone item is a flexible mold that will later be filled with another material.

Applications can include:

gummy;
chocolate;
resin;
plaster;
wax;
soap;
baking;
ice;
other compatible casting materials.

Possible mold structures:

one-piece;
slit;
two-part;
plug/core;
support shell;
multi-cavity tray.

The mold structure should follow the release path and casting workflow.

HCR/HTV Compression Molding

Use this route when the finished item itself is a compression-molded silicone product/component.

Project inputs can include:

part CAD;
material/hardness;
color;
tolerance/CTQ;
surface/branding;
tooling requirements;
production quantity;
inspection/packaging.

HCR/HTV tooling, unit price and timing differ from RTV mold manufacturing and are quoted separately.

HCR/HTV Tooling

Where a compression-molded product requires metal tooling, define:

approved part geometry;
parting strategy;
cavity count;
material;
expected volume;
dimensional/visual requirements;
mold ownership/custody terms where relevant.

Do not mix the terminology for an RTV casting master with compression tooling.

LSR Injection Molding

LSR may suit finished silicone components requiring an injection-molding route.

Project review can include:

part geometry;
LSR material requirement;
tooling concept;
parting/gate/ejection considerations;
inserts where relevant;
production volume;
inspection.

LSR should not be described as outside RUUIPON's legitimate project scope.

Silicone Overmolding / Insert Molding

For silicone combined with plastic, metal or another compatible insert/substrate, define:

insert material;
insert CAD/sample;
mechanical retention;
bond requirement where applicable;
interface geometry;
critical dimensions;
functional test;
assembly/use condition.

The overmold cannot be designed accurately without understanding the real insert.

Design & DFM

RUUIPON can review projects from:

STEP/STP;
STL/mesh;
drawings;
sketches;
physical samples;
photos/reference images.

DFM can address:

release;
undercuts;
split/core;
wall/support;
logo/detail;
multi-cavity layout;
tooling/process selection;
fit;
material/application;
prototype plan.

Design service: /custom-silicone-mold-design-service/

Prototype Validation

Prototype scope depends on the project.

Possible checks:

fit;
dimensions;
piece weight/volume;
logo/detail;
release;
filled handling;
insert retention;
surface;
assembly/function.

Define what the prototype must prove before it is made.

Material & Documentation

Material requirements can include:

hardness;
color;
food contact;
mechanical property needs;
temperature/use condition;
customer specification.

Documentation should be confirmed for the specific material/article/use/market.

Do not use generic “FDA/LFGB factory” language.

Process Selection Examples

“We need a flexible mold to pour resin.”

Likely start with RTV mold DFM.

“We need 50,000 finished silicone buttons.”

Review HCR/HTV or another suitable finished-part process.

“We need a precision LSR seal.”

Review LSR part/tooling requirements.

“We need silicone molded onto a plastic insert.”

Review overmolding/insert-molding DFM.

“We only have a physical sample.”

Start with sample measurement/design definition, then select the manufacturing route.

Frequently Asked Questions

Is RUUIPON an RTV-only supplier?

No. RUUIPON supports RTV silicone molds, HCR/HTV compression molding and tooling, LSR injection molding, silicone overmolding and finished silicone products.

Are all these processes performed on the same machine or in the same workshop?

They are different manufacturing processes. This page describes RUUIPON's supported project scope; specific production-site/equipment details should be confirmed for the project if they are part of the buyer's qualification requirement.

What is RUUIPON's standard MOQ?

RUUIPON's standard MOQ is 20 pcs. Tooling, unit price and lead time remain process-specific.

Yes. Send the object, material/application, geometry and expected quantity rather than choosing from a generic process chart.
