Technology of induction heating cannot be used for a specific application without a detailed technical analysis. First, it is needed to determine, whether a given task can be solved by the technology of induction heating at all. After this, a calculations of required power are performed and, depending on a shape of a heated object, the first inductor is designed. Efficiency and power parameters of this inductor are verified by a model. When desired results are achieved, a final adjustments of inductor and generator are made to meet customer demands.
We have successfully applied induction heating in several industries, including induction furnaces for melting of silver, gold and dental alloys, induction heating of enamel outlets, high temperature induction furnaces and devices for sealing of caps of plastic bottles and cans.
For applications of induction heating, we typically use generators of own production, which operate in the frequency range of 15 to 200 kHz with an output power up to 15 kW. The generators are usually supplemented by a temperature controller. In case of simple applications, power delivery loop is sufficient.
Laboratory devices, which we produce, are in the most cases built on our previous work in the Glass Institute. Usually these devices measure physical properties of glass. Next to these, we create two devices for the RMI Company, which are used to measure physical properties of coking coal.
During a custom manufacturing, we have devised some devices, which do not fit into previous categories. These are mostly resistive furnaces of non-standard design or purpose.
Laboratory instruments can be delivered together with an utility software, in which an user can give a name to a measured sample, write a comment to that sample or insert some other information to measuring procedure. Software is designed in a way, so computer is able to perform a measurement automatically. After measurement is finished, the results are evaluated automatically by the software. It is possible to perform a multiple measurements with one sample. In this case, as the result the average of all the measurements is taken. There is a built-in feature inside the software, allowing an export of protocol in PDF format (and the consecutive print) and an export of measured data in CSV format (for further data analysis e.g. in Excel).
