Candle Moulds: What type do I need?



Candle moulds are made with quite a big variety of materials including polycarbonate and PVC plastics, latex, silicone and polyurethane rubbers, glass, tin and aluminium metals. For this reason it is sometimes difficult to decide what mould will give you the best results.

A lot depends on how many candles you intend making with a particular mould and what amount of money you are prepared to outlay.

Light Weight Plastic Moulds

In the main these are confined to the vacuum formed plastic moulds, for low cost production. They are ideal for small flat backed candles, but can also be used for 3D figurines, using 2 part plastic moulds.

The problem with two part then plastic moulds is that they will deform in time due to the heat and are subject to leakage, even when you clamp them firmly together.

Latex Moulds

It is far better to use latex moulds than the light weight 2 part plastic moulds, when pouring third dimensional candles. They are easy to use, comparatively low in cost and finished candles can be stripped from the mould in much the way that you remove a pair of socks.

Metal Moulds

Most professional candles, that do not have external decoration, are made with long life metal moulds, either tin or aluminium. They are strong, easy to use and clean and give an excellent finish to the candles.

They are fairly expensive to start with, being individually hand made, but pay off in volume production manufacturing, with a long life.

Polycarbonate Plastics.

This is a strong plastic, equivalent to metal in length of life and is used for 3D candles with 2 part  moulds that do not leak like the light weight plastic do. This is due to the rigidity and tolerances possible with the injection moulding process, by which these moulds are made.

Polyurethane Rubber

While not exactly a rubber, this new boy on the block functions like a rubber. It is being used increasingly for professional candle production. The moulds are strong, pick up very fine detail and have a long life.

Most taper candles are made with polyurethane these days, due to the ease of use the rubber provides, combining flexibility with the required firmness for good handling.

Silicone Rubber

This is the answer to queries as to whether the mould can reproduce extremely fine detail, with the flexibility to enable easy removal of candles with undercuts in the design.

Practically seamless reproduction of candles is possible for most third dimensional objects, by making a block mould of the object. This is a mould made by pouring the silicone over the object and then a sharp knife is used to cut a seam down one side to release the object.This type of seam is virtually undetectable.


Most soy candles are being made using glass containers, where the melted soy wax is simply poured into the glass container, a wick is inserted and the candle is finished. A simple to make and attractive candle for beginners.

Previously most people chose to begin their candle making experience by making container candles, but increasingly people are beginning with candles with moulds. Candles made with moulds such as votives and pillars, are providing a much greater variety of shapes and designs to be made by the beginner.

While making candles with moulds is not necessarily more difficult than making container candles, they do demand a bit more technique, a few more supplies and most often require a greater time investment in determining the best use of additives and learning the techniques of candle craft.

Instead of pouring melted wax directly into a container where the candle will set up permanently, moulds are used to cool the candle into a desired shape and are then released from the mould. Using moulds requires the use of a release agent to make sure the mould comes off the candle once it has been cooled.

Internet marketing has enabled a much greater variety of moulds to be made available to online purchasers. You can now purchase moulds direct from our factory by contacting AldaxMoulds at

Depending on the volume of candles you are making, you will want to be sure that you purchase enough moulds to keep you continually pouring. You have to keep in mind that the moulds will have to remain on the candles, until the candles are hard enough to remove the mould which could be overnight. Volume discounts are available on all our moulds.

Another difference between container and candle moulds is the type of wax used in their production.

Candle moulds use medium to high melting point wax. The waxes are typically much harder than those used for containers. When purchasing your wax, be sure to read the wax descriptions to see if it is made for use in the type of candles you are planning to pour. Increasingly soy wax is being used for container candles.

Votive candles are one of the easiest candles you can make. They also require less wax to make than pillar candles, so they are ideal for the beginner. If you are unhappy with your initial results and need to make adjustments, it will require less wax to experiment with votives than it will with pillars.

Pillar candles are the other common type of candles. While votives tend to be offered in a few standard sizes, the size and shape options for pillars are far more varied. Not only do they vary in height, but also in diameter and shape.

The best resource for detailed instructions on how to make candles is to purchase a candle making kit. These kits contain full instructions on candle making together with the exact materials used in those instructions to produce perfect candles every time.
