Medium-frequency Induction Melting Machines
The heating of metal by induction has been in industrial use since the beginning of the 20th century, but it is only in the last few years that it has become possible to produce high-efficiency, low to medium power apparatus, due entirely to semiconductors.
CEIA's Induction Melting Machines have achieved widespread recognition in the field of precious metal casting.
Careful study has led to the choice of appropriate operating frequencies that have almost eliminated the problems of weight loss of the precious metal and surface oxidisation on melting.
Unlike in the case of high frequency furnaces, high-density surface currents ('skin effect'), which can violently oxidise the metal being treated, are not created.
The CEIA MAGMA electronic melters seriesThe CEIA MAGMA electronic melters series were designed to achieve maximum adaptability and flexibility of semi-finished products in precious metals.
The many years of experience in the production of medium frequency generators has enabled the creation of a continuous casting machine, of small dimensions, high efficiency, flexibility of use and appropriate response to the highest production requirements.
The CEIA continuous casting machine offers maximum security for the user, reliability, practicality, and simplicity of use, thus allowing the manufacture of high quality sheets and wiring, reducing the number of annealings and of laminating operations.
