RTV Mold RFQ Checklist You Can Copy

If you're quoting a custom RTV silicone mold, don't send name/email/application and wait for a blank price. Copy the checklist below, paste it into email or WhatsApp, and attach photos, a sketch, a sample, or CAD. A number from a three-field form is a guess built into the rubber. RUUIPON quotes poured cavities - resin master to RTV casting mold - from Bao'an (since 2018). Custom/simple 3D modeling is USD $50 when that scope applies. Prototype 3-7 business days after CAD lock. Production MOQ 20 pieces per design.

RTV Mold RFQ Checklist You Can Copy

This page is the public RFQ checklist. The same block lives on contact. Process gates after the RFQ sit in the process catalog. Steel/LSR *parts* → ask us.

Copyable RFQ checklist

Paste this block. Fill every line you can. A price without these lines isn't comparable.

RUUIPON RTV mold RFQ Date:

  1. Grams / fill

Target piece weight (g) or cavity volume: Water-volume map needed? yes / no Depositor nozzle count / pitch (if any):

  1. Formula / pour

What we will pour (pectin, gelatin, chocolate, epoxy, UV resin, soy/paraffin, CP soap, plaster…): Peak temperature (°C): Sticky / fatty / abrasive notes:

  1. What we copy

Photos, sketch, or CAD (STEP / STL preferred when dimensions are locked)? Or physical sample shipping? Scale / caliper readings if photos only: Who keeps the pattern after the job (customer / shop / both copy):

  1. Split / peel

Flat back / one-piece peel OK? Undercuts, bails, negative-draft letters, two-sided logo: Prefer two-part / plug / inner core / you decide:

  1. Support / nest

Rigid support or nest required? yes / no / you decide Support preference (wood/metal box, printed nest, none): Tray size limits (L x W x H, mm): Cavity count target vs tray stiffness:

  1. Certs / food-contact

Face touches food? yes / no Markets: US 21 CFR 177.2600 extraction / DE-EU LFGB BfR XV / both / craft-only Food types: aqueous / fatty / acidic / dry Do not send an LSR spatula FDA PDF as this mold's proof ISO 3302-1 class on the drawing (if any) - class, not the word "precision":

  1. Quantity and commercial

Prototype qty: First production qty (MOQ 20 per design after sample approval): Custom/simple 3D modeling needed? ($50 when that scope applies) yes / no / have STEP: Monthly dumps / pours: Recast of the RTV skin: included or extra Incoterms: EXW / FOB / DDP Who owns jacket and CAD (write it; tooling charge ≠ unrestricted ownership):

Send that to [email protected] or WhatsApp +86 135 3006 2969. If a line is unknown, write "you specify" rather than deleting it.

Common mix-up: a thin web form is an RFQ

Name, work email, and "application = gummy" is how you get a number you can't use. Two shops will assume different grams, different splits, and different cert packs. The checklist above is the RFQ. Quote page: custom mold quote. Cost drivers: mold cost.

What happens after a complete pack

  • Structure call: open-back vs keyed split vs plug vs jacket.
  • DFM mark-up if the STL cannot leave - DFM review.
  • CAD lock, then 3-7 day prototype.
  • Written pass/fail, then MOQ 20.

A pretty STL with silent units does not start a serious clock.

Typical shop values

Reference values only. Confirm material-specific limits against the supplier’s technical data and agree project acceptance criteria before production.

Failure: two prices, two objects

Symptom: One PI is an RTV jacket; the other is an LSR cold-runner; purchasing files them as "mold cost." Or food docs billed later because the RFQ said "FDA."

Confirm: Line-item 3D ($50 when in scope), master, rubber, split, jacket, sampling, recast, certs, Incoterm.

Fix: Re-quote the same object with this checklist. Don't accept a lump "mold" number.

Worked example: 8-cavity bar, chocolate, food-contact

Buyer sent STEP, 120 × 60 × 12 mm, recessed brand 0.4 mm, tempered chocolate, ~500 pours/month, US+EU docs, jacket undecided. Complete RFQ let us name keyed two-piece plus jacket, freeze logo depth, prototype 3-7 days after lock, then MOQ 20. A name/email/"chocolate mold" form would have guessed the split and the cert pack.

What to ask when you're sending an RFQ

  • Can two suppliers fill this same block so the numbers compare?
  • Which lines are still "you specify"?
  • Is the object an RTV cavity or an HTV product or mold RFQ here, or a high-volume LSR *part* tool - ask us?
  • Who keeps master, jacket, and CAD after the tooling charge?
  • Food: 177.2600, LFGB, both, or craft-only - on this recast?

When this checklist is the wrong form

If you need thousands of vulcanized silicone *parts* or a steel gummy *part* tool, don't fill this RTV block - open an HTV product or mold RFQ here, or ask us if you need a high-volume LSR cold-runner tool. If you're buying a catalog ice sheet that already matches, you don't need seven sections. Geometry can override quantity: a one-off resin hook still needs split and keys filled in.

Send the filled block, not a generic quote request

Paste the checklist to contact. We'll tell you which process catalog gate applies. Send the filled block, not a three-field form.

Skip quoting from three fields

Skip treating "FDA" as a checkbox without naming 177.2600 vs LFGB on this article. Silent STL units make two PIs diverge. EXW and DDP are not the same number. A tooling charge is not unrestricted CAD ownership.

RUUIPON Mold Structure Decision:

  1. Can the part leave? - unknown -> DFM review
  2. Can the part leave? - hook / two-sided logo -> Split mold
  3. Can the part leave? - yes, flat or peelable -> Loaded or 10A-20A?
  4. Loaded or 10A-20A? - yes -> Jacket
  5. Loaded or 10A-20A? - tiny shallow -> Open-back
  6. DFM review -> Can the part leave?
  7. Split mold -> CAD lock
  8. Jacket -> CAD lock
  9. Open-back -> CAD lock
  10. CAD lock -> 3-7 day prototype
  11. 3-7 day prototype -> MOQ 20

FAQ

Is this different from the contact form? The form logs the job. This checklist is what we quote from. Fill both; don't skip pour, size, qty, or the food-doc path.

Do I need every line? Unknown is fine if you write "you specify." Deleting a line is how two PIs diverge.

Does a complete RFQ get a 24-hour number? A complete pack gets a structure call, not a fake-precise unit price on missing grams. Timing depends on files, not a slogan.

Is 3D always $50? USD $50 when that custom/simple modeling scope applies. Complex reverse-engineering is scoped first.
