Question

i have a project, which is to automate the process of making a candle. i need to have a custom made mold for the candles. what material , like, what should be the made of my mold, say should it be aluminum or something... i need a material that can heat easily and cool out easily as well. what material should i have my mold to be made of.

to the guy who works at a commercial candle factory. is your system automated??? like how you make your candles???

coz my project is to automate the system of a commercial candle manufacturer. and we are making a tea lit size candle...

Answer 1

I work a commercial candle making company all candles except for tapered are molded under pressure from granular wax, we produce about 100,00 tea lites a day for example

the process is completely automated, it is very lengthy and I would have to take a considerable amount of time to tell you

Answer 2

Most candle making molds are made of aluminum. Could use a wood form, but cover the inside with heavy duty foil for easy release. I have also used pvc pipes cut level, that way I can have several at once. Yes the wax leaks slightly from the bottom, easy fix when hardened. Cleaned food cans, and almost anything with little or no give. I have used a bucket filled with sand, making an indentation in the center with a coffee tin and keeping the bottom level (so the candle when hardened is flat. Pour the wax slowly into the sand form and let harden. Remove it and brush off the sand that you can with a paint brush,(throw away variety). That should give you a start.If this is your first time at pouring candles be sure to spray on a bit of oil or buy Silicone Candle Release at a crafting store. The spray oil works fine but, you need to wipe it off after the candle is hardened. Good Luck

You may have to clarify what shapes you are considering for your candles, and if this is to be an at-home project or something for commercial use.

Candles of differing shapes, such as square, rectangular, star-shape will have vertical sides, and they can be made with tin. Tapered shapes permit easy removal of the candle when cooled and inverted.

Tin has been a proven item for years. In my home candle-making work tin does well with air cooling and for chilling in water, in both vertical or angled dipping.

Tin can be formed into many shapes, and then used in a two-part mold.

Two part molds offer the advantage of easy removal. In early 20th century tin was the standard, occasionally with wooden blocks used as keepers, and otherwise steel collars, as two-part molds require a secondary means of holding them closed during the pouring and initial cooling stages.


Aluminum offers different advantages, as you could use it in a straight sided mold to be used the same as tin for the candles mentioned above, or it can be cast in two-part, (or even three-part,) shells to allow virtually any shape and you can have whatever wall thickness is desired.

Cast aluminum molds would have to be professionally made as a mold must first be made to cast the liquid aluminum into the desired shape.
