Growcontrols manufactures Induction Melting Systems for High Quality Steels. Growcontrols is an ISO 9001:2000 accredited company. The company manufactures high power inverters, rectifiers and power supplies for industrial and traction applications. The Induction Melting Systems for High Quality Steels is usually accomplished by heating the metal in a crucible made from a non-conductive refractory material. The charge of metal within the crucible is melted down to liquid form. This process is commonly used to produce high quality steels and nonferrous alloys for casting operations. The liquefied metal is poured into a cavity having the desired shape. The metal solidifies with a minimum of shrinkage, after which the mould is removed to reveal a finished, machinable product.
