The main production methods are: pressing, drawing, casting and dipping.

The main production methods are:

With each of these production methods a very good candle quality can be achieved. However, it depends crucially on the optimal coordination of all factors of influence, i.e. the wax type, the dipping masses, the wick and the production method, not only on the type of the production plant.

Candles are often then processed further using dyes or varnish.

Pressing

Pressing is done in special pressing machines. This technology is suitable for tea lights, pillar candles and dinner candles. There are two common methods:

Extruding press method

The grained candle raw materials and the wick are compressed in a pipe under high pressure. After pressing, an endless thread comes out of the machine and is cut into pieces with the desired length.

Powder press method

Here the wick and the powdered burning mass are pressed to a candle. Tools can be interchanged using this method so that candles of various lengths and diameters can be produced by one machine (stamp press).

 

Drawing

During drawing, the wick is pulled through a melted mass of wax and a layer of wax settles around the wick. This process is repeated until enough of layers have settled around the wick and the candle thread has reached the desired thickness. In common candles, the layers can be seen like the rings on the trunk of a tree.

Drawn candles are fully dyed. Thanks to this special manufacturing form, they have a very long burning time and a very attractive flame.

 

Casting

Casting is actually the oldest production method at all. For casting, you need a form. The wick is clamped into the form that is filled with liquid wax afterwards. After it has cooled down, the finished candle can be removed. This production method is especially favoured for manufacturing special candle shapes that cannot be realized by using other production methods.

 

Dipping

This production method involves the repeated dipping of the wick into a liquid mass of wax until the desired candle size is produced. Typically, dipped candles peak towards the top and are fully dyed.

 

Further processing

Basic candle forms may be produced using these methods. The candle production method chosen is always based on which method is best in terms of production economy and results.

Most candles are processed further, e.g. they are dyed or decorated. The main methods for this further processing are:

Colouring

By dipping into melted coloured wax, a colour coat can be applied on raw candles. The dipping masses are dyed with pigment colours, which are UV-stable. So the candle becomes lightfast and still keeps its decorative character for a long time. The dipping wax consists of materials with a higher melting point, i.e. it melts later than the candle core. When burning the candles, this leads to the formation of a distinct cup rim and prevents the candle from dripping.

Varnishing

With dipping candles into clear or coloured lacquers itsĀ“ surfaces can become atypically shiny and brilliant.

Others

Candles can also be processed with placing patterns (e.g. by using silk screen printing) or applications.
