How Much Does a Custom Silicone Mold Cost?

You won't find a useful catalog price for a custom silicone mold. Two molds can share the same outer size and still not share a number. A shallow logo stamp is mostly rubber and a simple pattern. A planter with a hollow inside, plus a rigid support around a soft skin, is pattern work, a temporary silicone copy, a resin production mother, more mixed silicone, and more hand work every cycle. If you're asking how much, send the file and what you'll pour. We'll price that job instead of guessing from a photo.

RUUIPON quotes RTV casting molds in Shenzhen - the flexible cavity you pour chocolate, gummy, resin, wax, soap, plaster, or ice into. DFM on your file is free. CAD is about USD 50 when we build or revise the 3D model. A prototype is usually 3-7 business days after CAD lock. Production is MOQ 20 per design after you approve that sample. Those three numbers are the ones we hold on the RTV path. Rubber weight, splits, a support shell, packing, and freight get quoted for that mold. We wouldn't put a catalog dollar total on this page.

What should be on separate lines

Ask for one-time work and repeating work on separate lines. A single "mold" number hides what you pay again on the next reorder.

• DFM review - a free engineering check before anyone prints a pattern
• CAD - about USD 50 when that 3D scope applies; skip it if your STEP is already mold-ready
• Pattern and resin production mother - we print a pattern, often make a temporary silicone copy, then cast the hard mother we pour production rubber against
• Prototype RTV cavity - the first mold you fill with the real material
• Production molds - unit price at MOQ 20 of that design
• Pack and freight - EXW, FOB, or DDP named, not implied
• Food-contact documents - only if the face touches food and you named the market

A reorder of the same approved design shouldn't reopen CAD and mother cost unless the geometry changed. Write who keeps the resin production mother on the first PO. Paying a tooling charge isn't automatic file custody.

What actually changes the quote

The file. A clean STEP in millimetres is cheaper than four phone photos with no scale. Photos can start DFM. If grams or fit matter, we still want a sample or a locked model before we freeze the mother.

What you pour. Pectin, tempered chocolate, epoxy, hot wax, and wet concrete need different molds. The material decides how it releases, how hot it gets, and whether food documents belong on the quote. A craft tray shouldn't pay for a food pack you won't use. A food tray shouldn't skip the pack and print a claim later.

How the mold is built. A simple one-sided stamp is one path. A keyed two-part split, a plug, or an inner core is more labor. A tray that holds a lot of material, or a soft skin, often needs a rigid support shell so the cavities don't sag when they're full. Skipping that support to win the unit price is how the outer pockets go heavy on the first real pour.

Cavity count. More pockets can drop cost per pour and raise rubber, tray span, and sag. There is no honest rule that 16 cavities cost 1.2 times an 8-cavity sheet. Lock the shape first. Then add pockets.

Quantity. Production MOQ is 20 of the same design after the prototype. Two designs are 20 each. A paid one-off prototype is a test, not a lower production MOQ. That split is on low-MOQ custom silicone molds.

How to spend less without buying a bad mold

• Freeze millimetres and logo depth before the mother is cast. Each CAD loop after that is a recast or a new pattern.
• Send the real casting material. Signing off a sticky pectin job with water is how you pay twice.
• Don't buy 48 cavities while the logo is still changing.
• Drop detail that never faces the customer.
• Prototype the risky geometry, then run 20 of that design.

Compare quotes on the same kind of mold

Typical mix-up (not a named customer): one shop quoted a pour cavity. Another quoted a compression or injection tool for a silicone part with the same outline. Purchasing filed both as "mold cost." The cheaper PDF isn't a saving. Name the deliverable: an RTV cavity you pour into. Then compare CAD, mother, rubber, support shell, prototype, and recast as lines. Factory context: custom silicone mold manufacturer.

Two jobs, same tray size

Hypothetical, not a priced catalog pair. Both RFQs say 200 mm tray. One is a shallow soap logo stamp - one-sided, one pattern, not much rubber. The other is a resin planter with a hollow that needs a plug, plus a rigid support around a soft skin. Same word "mold" on both emails. The second job has more mixed silicone, a split or plug, a support shell, and more hand work every cycle. We wouldn't put those on one unit price. We also wouldn't invent a website dollar total for either one.

What we can honestly quote from photos

A measured photo set can start DFM and a range. It cannot honestly freeze grams, a hidden undercut, or a logo depth in millimetres. If the first number you need is "can we tool this at all," photos are enough. If you're about to print ads on a 4 g pectin piece, send a sample or lock CAD before we cast the mother. We'd rather send questions than a fake-precise unit price.

Treat the prototype as the test. Treat the 20 as the lot that copies the approved face.

Don't pay for lines you don't need

Food-contact documents belong on the quote only when the face touches food and you named the market. A craft resin tray should not pay for a chocolate pack. Freight is EXW, FOB, or DDP as written - not "shipping included" with no destination. A rigid support is a structure call we make before the first full pour, not a surprise add-on after the skin sags.

HTV process products and HTV/HCR molds are a different RFQ from the same shop. Free DFM. Don't copy this page's MOQ 20 or 3-7 day window onto that job. Process notes: RTV vs HTV silicone molds.

When this page is the wrong read

This page is about what moves a custom RTV pour-mold quote. It is not a price list. If you need the lot-size rules - what "20" does and does not mean - use low-MOQ custom silicone molds. We're the wrong shop if you need a stock catalog tray shipped next day from a US warehouse. We wouldn't pretend we have that inventory.

HTV process products and HTV/HCR molds are quoted here as a separate RFQ. Free DFM. Don't copy this page's RTV MOQ 20 or the 3-7 day window onto that job. Say HTV on the RFQ so we don't price an RTV tray by mistake. High-volume LSR cold-runner part tools sit outside what we quote on this page.

What to send so we can price it

File or measured photos, what you'll pour, target size or grams, cavity count if you care, how many molds you want after the sample, destination, and whether the face touches food. That's enough for a usable number. Path if you want the steps: custom silicone mold services. Send files for a quote.

Cost questions

Why is there no dollar total on this page? Rubber weight, splits, and support work don't share a catalog SKU. Send the file.

Is USD 50 the mold price? No. That's CAD when we build or revise the 3D model. Mother, rubber, prototype, and the 20 production molds are separate lines.

Does MOQ 20 apply to the prototype? No. The prototype is the test after CAD lock. Production MOQ is 20 of that design after you approve it.

Can I get a price from photos only? You can get DFM and a range. We won't freeze grams or a hidden undercut from one unscaled shot.

Can I skip food documents to save money? Only if the cavity is craft-only. If the face touches food for the US or EU, name the market. Don't print a claim you didn't buy.
