The production of lights is technologically speaking uncomplicated. However, in order for the entire manufacturing process to be effective and productive, it is necessary to have specialized machines and appropriate knowledge.
The composition of the fuel and the type of wick are selected individually for each kind of light with regard to size, weight and purpose of the light. The fuel consists of a mixture of oils, paraffins, stearins, colourings, fragrances etc. Together with the wick it has an essential influence on the quality and the burning time of the light. The wick should be chosen so that it does not 'burn out' the light too fast, but does also not cause the light to go out by itself. In order for the wick to remain in a vertical position, it must previously be reinforced for the entire burning time. We achieve this by 'bathing' the wick in paraffin.
The wick with a small round plate at its end (which 'holds' the wick in place while burning) is placed exactly in the middle of an appropriate vessel (made of glass or – in the case of light cartridges – in a plastic cup made of PP). This construction is then filled with a homogenous fuel mass and cooled in special air tunnels. The ready products are packed according to the instructions of the customer (in packets, boxes, packets and boxes).
In our company all the above processes have been automated. Thus we were able to considerably reduce the production costs and can achieve a productivity of over 8 million lights per month. The above description of the production technology is merely a survey and does not give detailed information about all the activities involved.
