Mold-tooling routes
RTV vs HTV Silicone Molds: Two Mold-Tooling Routes
RTV pour cavities vs HTV/HCR compression tools—two mold-tooling routes. RUUIPON quotes both molds and HTV products. Name the object.
Buyers often ask for an “HTV version” of an RTV pour tray. Those are usually two different objects: a flexible RTV silicone casting mold you pour into, or an HTV/HCR compression mold — the steel/compression tool used to press solid silicone. RUUIPON quotes both mold-tooling routes in Shenzhen, and also quotes HTV process products (vulcanized HCR articles) when that is what ships.
Name the object before you ask for a unit price.

The shortest split
| You need | What you buy on RUUIPON | Quote posture |
|---|---|---|
| Flexible cavity copied from a master; complex peel; easy recast | RTV silicone casting mold (open-back, two-part, plug/core, jacket when needed) | Photos/sketch/CAD → resin production mother → batch RTV |
| Steel/compression tool for solid silicone (HCR/HTV) | HTV/HCR compression mold | DFM on the tool RFQ; quantity and lead quoted by project |
| Finished vulcanized HCR articles / compression parts | HTV process products | Product RFQ on this form; matching tool DFM as needed — quoted by project |
HTV is not the production upgrade of an RTV mold. Recast RTV if you still need a pour cavity. Open an HTV/HCR mold RFQ if you need compression tooling. Open an HTV product RFQ if you need vulcanized articles.
What RTV is on this floor
After CAD lock, a typical path is: 3D-printed pattern → often a temporary silicone flip → resin production mother → batch RTV silicone casting molds. The resin production mother is the durable master we pour against. A jacket / support shell is a different noun — it keeps a soft RTV skin from ballooning under a wet dump.
RTV can be real production tooling for pour work (food trays, chocolate, gummy, resin, candle, soap, sculpture), not only a “prototype label.”
Commercial (RTV casting molds): For applicable custom RTV production, MOQ is usually from 20 molds per design after approval. Prototype quantity is separate. Sample molds are usually 3–7 working days after CAD lock when the project is suitable. DFM review is free; when we build or revise your 3D, CAD is typically about USD 50 per design.
What HTV/HCR means here
An HTV/HCR compression mold is the heated compression tooling for solid silicone. An HTV process product is the vulcanized article that comes out of that process (or an equivalent compression path).
For HTV molds and HTV products, quantity, lead time, and cycle expectations are quoted by project after DFM on the actual tool or part. Do not copy RTV commercial windows onto the HTV line.
Worked judgment (same brief, different object)
| Buyer brief | Likely object | Why |
|---|---|---|
| 12-cavity soft bear pour tray; CAD still moving; food-contact pour | RTV casting mold | Soft peel, recast path, prototype then production set |
| Steel/compression tool so a plant can press solid silicone parts | HTV/HCR compression mold | Tooling RFQ — not a pour cavity |
| Finished solid silicone kitchen/OEM parts | HTV process product | Parts RFQ — not an RTV tray PO |
If the spreadsheet mixes “tray unit price” with “steel tool amortization” and “HCR part unit,” split the lines before you compare suppliers.

FAQ
Is HTV the production version of my RTV tray? Usually no. If you still pour into a flexible cavity, stay on RTV (recast). If you need a heated compression tool or vulcanized HCR articles, that is a separate HTV RFQ on RUUIPON.
Can you quote both the RTV mold and the HTV tool? Yes — as separate line items with the object named on each.
Do you invent a standard HTV quantity or lead time on this page? No. HTV molds and HTV products are quoted by project after DFM.
Where do chocolate / bake cavity specs live? Product pages own cavity engineering. This page owns the tooling-route decision.
