Candle Wick Hole: Pilot, Pin, or Slit
The wick feature is often the smallest geometry in a candle mold and the first place the rubber tears. If you are locking how the wick leaves the RTV, this page is that choice: molded pilot, removable pin, or a knife slit. A slit in thin silicone behaves like a crack starter.

RUUIPON pours platinum RTV tools in Bao'an, Shenzhen (Licheng Technology Industry Park, Xinhe Blvd, Shajing; USCC 91440300MA5FAXCN9W) since 2018. Simple 3D is USD 50 when that CAD scope applies. Prototype is 3-7 business days after CAD lock. Production is MOQ 20 pieces per design. Candle tools are not food-contact trays.
Where this page sits
Buy the mold on custom silicone candle molds. Handles, logos, and split vs plug live on sculptural candle mold structure. Seam flash vs wax lock lives on candle seam and wax sticking. This page covers the wick path.
Four ways to make the path
Molded pilot: a formed hole or short channel. Repeatable if the local wall is thick enough. Removable pin: the pin makes the hole; the silicone is not the slit. Good when you will recast. Piercing the skin: a knife cut. Fast, and it starts a tear. Post-drill the candle: the mold has no wick feature. Use it when the geometry cannot survive a hole.
Typical shop values
Reference values only. Confirm material-specific limits against the supplier’s technical data and agree project acceptance criteria before production. No universal hole diameter.
| Item | Typical shop value |
|---|---|
| Treat as | Fatigue feature: stretch + notch + wax leak + operator pull |
| Avoid | A sharp slit in a thin wall as the production method |
| Diameter | Match wick + seal method, not a catalog default |
| Inspect | First 20-50 pulls at the wick zone, not only dump 1 |
| Keep the hole off | The parting land when you can |
| 3D / CAD | USD 50 when that modeling scope applies |
| Prototype after CAD lock | 3-7 business days |
| Production after written pass | MOQ 20 pieces per design |

Seal and reinforce
During the pour the hole can leak wax. Write the seal: pin in place, plug, or a molded boss that the wick clip sits in. Local thickness or a replaceable pin can protect the rubber without making the candle harder to peel. If the wick sits on the seam, flash and leak fight the same zone.
Worked example: slit tear
Typical job, not a named PO. Operator knifed a 2 mm slit after the first skins shipped. By pull 30 the slit ran into the logo. We recast with a molded pilot and a pin. The empty render had no wick feature at all.
When this page does not apply
This wick page does not replace the candle product or sculptural structure. It does not apply to food trays. HCR compression products and molds stay on a RUUIPON HTV RFQ. High-volume LSR cold-runner part tools are a different RFQ - ask us.
RFQs we will not accept as-is
"Just slit the silicone" as the production wick method. A wick hole on the parting land with no seal plan. Sending an HCR / LSR part through this RTV wick page.
Matched next step
Send candle height, wick size, whether a pin is acceptable, and where a seam is forbidden. We will name pilot, pin, or post-drill. "Candle mold with wick hole" is not enough.

FAQ
Is this the candle product page? No. Buy the mold there. Wick path lives here.
Can we knife the hole after pour? Not as the production method. It starts a tear.
Do you hang FDA papers on candle tools? No.
When is USD 50 3D in scope? Simple cavity-map modeling. Sculpture rebuild is quoted separately.
What is MOQ after a pass? 20 pieces per design.
