RFQ Pack for a Sharp-Edge Resin Dice Mold | RUUIPON

To RFQ a resin dice mold, lock the arris (how sharp the edge is), pip or font depth in millimetres, and whether the set is a split block or a keyed family. Phone photos of a "sharp" metal die will not survive SLA rounding. $50 CAD when that scope applies is how we put a real edge on the master. Dump is usually PU or epoxy resin — name peak °C. Prototype is 3–7 business days after CAD lock of the edge. Production is MOQ 20 pieces per design.

RUUIPON pours dice tools in Bao'an, Xinhe Blvd, Shajing, since 2018. Mix is 1:1 or 10:1 by weight. Platinum shrink after a full cure is typically about 0.1–0.3%. Product: resin molds. LSR *parts*: wydsilicone.com.

Does not apply when you wanted food gummy dice (that is a food tray RFQ, platinum, 177.2600). It also does not apply to CNC steel for injection dice. Tin can be craft resin; still name it.

Arris, pips, and a split that does not sit on an edge

An arris that is too sharp for 10A will tear. An arris that is too round is a "blurry die." Put a radius or a knife edge on the drawing. Pips that are shallower than the print layer vanish. Split faces should hide in a pip row or a number plane, not cut a corner.

The photo that would prove a dice RFQ: millimetre scale on a pip, CAD section of the arris, first dump. A glitter hero shot is not depth.

ISO 3302-1 M2 is dump class. Sharpness is a CAD call.

Failure: rounded dice from a "sharp" STL

Symptom: first PU dumps look tumbled.

Cause: SLA rounded the edge; no $50 CAD; split on the arris making flash on the corner.

Fix: CAD the edge, move the split, recast.

Typical shop values

Caption: typical shop values, not a named PO.

RFQs we would not run first

We would not recommend a split through a knife edge.

We would not recommend FDM as the sharp-arris master.

We would not recommend food tin for gummy dice.

We would not recommend skipping pip millimetres.

A tooling charge is not a sharpness warranty without a drawing.

Worked example: D20 set, photos, rounded pips

Seven-die set, photos. $50 CAD, pip depth locked, split off corners, platinum 20A two-part. Prototype 3–7 business days after lock. Production MOQ 20 of that design. Related: PU resin, jewelry resin.

Pressure pots on the dump are not vacuum on the rubber. Degas the platinum. Torch myths stay off the tool.

Keys crush in the carton — spacer. Invoice as molds, not toys. Rev on the jacket.

Min-feature: pips shallower than layer height vanish. Draft the master so rubber peels; dump draft is a second sentence.

Family mold vs seven dedicated tools is a qty and changeover call. Geometry can override. We would not hide seven CAD changes in one "set" price without listing them.

Prototype 3–7 business days after CAD lock. MOQ 20 per design. Mix 1:1 or 10:1. Shrink about 0.1–0.3%. USD $50 CAD when that scope applies. ISO 3302-1 M2 as a common dump class. Loaded sag about 0.5–1.5 mm if you skipped a jacket on a sheet of small dice. Shop since 2018. [email protected] +86 135 3006 2969. A tooling charge is not unrestricted ownership of the arris CAD. Recasts follow the locked edge unless you pay to change it. We would not raise Shore first to fake sharpness. CAD the knife, then pick Shore for peel.

PU kills RTV faster than a gentle epoxy. Budget recast. Full cure before a hot dump. Summer split cups. 10:1 needs scale d=0.1 g on small shots.

A D20 family with seven shapes is seven cavity CAD jobs even if they share a flask. List each. MOQ 20 per design can mean 20 of the set or 20 of each — say which.

Glitter dumps scratch 10A. Name abrasive fillers. We would not promise optical clarity from the mold; that is the resin and the pressure pot.

Font on a pip face is min-feature again. A 0.2 mm serif on a D6 is a blob. Cut millimetres you can wet with a detail coat.

If the master is metal, draft for rubber peel still applies. A zero-draft steel die as a master will lock 10A.

CAD lock includes arris, pips, split, dump. 3–7 business days after that. MOQ 20 per design. USD $50 CAD when that scope applies. Mix 1:1 or 10:1. Platinum shrink about 0.1–0.3%. ISO 3302-1 M2 as a common dump class. Jacket if a sheet of small dice will sag about 0.5–1.5 mm.

Customs: mold tools, not toys. Pack keys so they do not kiss. Food gummy dice go to the platinum food tray RFQ, not this resin page. We would not torch face bubbles on the platinum pour. Vacuum the cup. Alcohol on wet rubber is not a process. Dirty cups and sulfur sticks inhibit dice faces the same as jewelry. Nitrile, dedicated PP, slug 20 g if the master is SLA. Seal the print. Release is not sealer. Draft the master. Sharpness lives in CAD, not in a kitchen scale 10:1 rounding error — use d=0.1 g when B is small. Full cure before a hot PU dump; two-day wait is not the 3–7 day calendar. Summer splits the shot. Winter warms the kit. Rev on the jacket so a recast after PU wear is still the locked arris. Photograph keys at pack-out. Invoice as mold tools. Shop since 2018, Xinhe Blvd, Shajing, Bao'an. [email protected], +86 135 3006 2969. A tooling charge is not unrestricted ownership of the arris CAD. Recasts follow the locked edge unless you pay to change it. We would not raise Shore first to fake sharpness. CAD the knife, then pick Shore for peel.

Mix-up: sharper Shore makes sharper dice

Shore is peel and tear. The arris is CAD. The other mix-up is a metal precision die as the master without draft for rubber peel.

What to ask when you're buying a dice tool

• Arris and pip depth mm?
• Split location?
• Resin chemistry and pressure?
• Set as family inserts or seven tools?
• After CAD lock, 3–7 business days, then MOQ 20 / design?

When does 3–7 days start? At CAD lock of the arris.
