Pillar vs Container Candle RTV Mold Tools | RUUIPON

A pillar-candle RTV mold is a cavity you peel off a free-standing wax column. A container candle is wax poured into a jar, tin, or ceramic that *stays* the package — that glass is not a silicone tool, and we would not wrap platinum around a mason jar so you can "mold the container." If you need a silicone *sleeve* to hold a jar while you pour, say so; that is a fixture, not a cavity. Wick wells, foot draft, and a pour cup belong on the pillar RFQ. Container work belongs on a wick-centering and jar-procurement conversation we are not selling as an RTV SKU.

RUUIPON pours pillar and novelty wax tools in Bao'an, Xinhe Blvd, Shajing, since 2018. Prototype is 3–7 business days after CAD lock. Production is MOQ 20 pieces per design. Simple 3D is USD $50 when that CAD scope applies. Mix 1:1 or 10:1; platinum shrink typically about 0.1–0.3%. Steel/LSR *parts*: wydsilicone.com. Product path for pillars: custom pillar candle molds.

Does not apply when you meant a chocolate "candle," a food-contact claim on paraffin, or a WYD compression *part* that looks like a candle. This is not the WYD candle-product essay. We would not spec tin for a food-adjacent wax you plan to skin-contact as a balm without naming that dump. CBD/THC: tooling only.

Peel the pillar; do not RTV the jar

Pillar / novelty / tart. Open-back or two-part depending on undercuts. Straight columns with draft often peel as a glove or a simple open-back tube. Sculpted pillars with arms or deep texture want a split. Jacket if the wax dump is tall and the skin is 10A–20A.

Container. The cavity is the jar. RTV around the jar only if you are making a *copy of the jar as a wax pillar*, which is a different SKU (a pillar that looks like a tumbler). Copying a branded glass from photos without rights is not a $50 CAD.

Wick well. A designed pin or a post on the master gives you a wick hole. Drilling after every dump is a labor tax. Put the pin on the lock.

Pour cup / foot. Pillars need a defined foot so they sit. A container has the jar foot. Do not mix those drawings.

The photo that would prove a pillar spec: mold open, wick pin in millimetres, draft on the column, a witness pillar beside the cavity. A lit jar on a sofa is a container photo, not a tool photo.

Wax temperature vs rubber, and what is not food

Pour temps for paraffin and soy are a named band on the RFQ, not "candle heat." We would not spec a baking-tray Shore because someone said "hot wax." Platinum food-path rubber used for candles is a *craft* cabinet after fragrance oil. Do not wash-and-switch to chocolate.

ISO 3302-1 M2 is a rubber class if you care about the wax article's dimensions. It is not a burn-safety cert, and we will not invent one.

A two-piece pillar that looks like a sculpted character still follows Structure Decision, not a jar SOP. If the arms hook, split the rubber and put the sprue on a hidden foot. Container buyers sometimes send a character jar (a ceramic house) and want "the inside molded." That is still a container unless they will demold a free-standing house-shaped pillar. Write which SKU ships.

Fragrance and dye stain. Plan recast from the sealed master, not infinite life.

Tall skinny pillars also sag in a jacket-free 10A tube: the wax is hydrostatic for a few minutes. A simple board or a cheap printed shell is enough on a 150 mm column; a 400 mm column wants a real mother mold. Do not steal Shore from a baking tray to skip that shell.

Failure: container buyer sent a jar and asked for a mold of the inside

Symptom: RFQ is a pint glass and "silicone mold so I can pour candles."

Cause: mix-up between package and tool.

Confirm: will the wax leave the cavity as a free pillar, or stay in glass?

Fix: if pillar-that-looks-like-a-glass, we model the *outer* as a peelable shape with draft. If container, buy jars. We would not wrap a glove around glass and call it a production mold.

Candle habits we would not recommend

We would not recommend RTV around a mason jar as a container "mold."

We would not recommend skipping the wick pin on a production pillar.

We would not recommend a one-piece peel on a sculpted figurine pillar with hooks.

We would not recommend using the same well for soy candles and chocolate.

We would not recommend a food-contact pack as a burn claim.

Worked example: 70 × 150 mm column, no wick pin

Soy pillar, 70 mm OD × 150 mm, buyer open-back tube, drilled wicks by hand. Drift on every SKU. We added a wick pin on CAD lock, 1° draft, platinum 1:1. Prototype 3–7 business days after lock. $50 CAD applied because the OD was a tape measure on a photo. Production MOQ 20 of that design.

Mix-up: the jar is "the mold we already have"

Glass is packaging. RTV is the tool for a pillar you demold. Related: products candle molds, contact.

What to ask when you're buying

• Pillar (demold) or container (stay in jar)?
• Wick pin diameter and depth, in millimetres?
• Pour temp band of the wax?
• Fragrance — this well leaves the food cabinet?
• After lock, 3–7 business days, then MOQ 20 / design?

FAQ

Do I need a silicone mold for container candles? Usually no. The jar is the cavity. RTV is for pillars and novelties you demold.

Can you mold my glass tumbler in silicone so I can pour into it? We will not wrap production platinum around a jar as a "container mold." If you want a pillar that *looks* like a tumbler, that is a different peelable CAD.

Where does the wick hole come from? A pin on the master, locked in millimetres. Drilling every dump is how diameter drifts.

Can I use a candle mold for chocolate later? No. Fragrance oil retires the well from food. Recast a dedicated food tray.

What's the prototype clock? 3–7 business days after CAD lock. USD $50 when we must model. MOQ 20 per design. Mix 1:1 or 10:1.
