LIVARNA TITAN d.o.o. is a specialized producer of high-quality white heart malleable iron castings with a wide range of mechanical properties, using the latest casting processes in a modern, automated foundry line. Raw material is melted in a medium frequency melting furnace. Chemical composition of molten is constantly monitored by emission spectrometers. Products, with or without cores, are casted on a vertical, automated DISAMATIC line.

The foundry is capable to produce parts ranging from 0,1 kg to 10 kg. All castings are cleaned with steel granulate in an automatic blasting machine. Heat treatment takes place in a furnace with automatic control of the process and atmosphere. With the heat treatment process we can achieve the change of cementite into ferrite and graphite. With this kind of heat treatment – tempering of the brittle cast iron, toughened white malleable cast material is produced. We can produce products with various shapes, from simple to complex, which have good mechanical properties, especially when forging or plastic transformation is too expensive and steel casting too complicated. The important advantage of white malleable cast iron is also it’s good weldability. Because of good viscosity, malleable cast iron is also possible to use for products with difficult thin-walled forms with a good surface quality. Relatively high strength and toughness of white malleable cast iron allows products to be used in applications with high dynamic and impact stress. Good weldability of material EN-GJMW-360-12W (GTW-S38) opens a possibility of use in sophisticated welded constructions. White malleable cast iron has excellent handling properties and is corrosion and wear resistant.

Modern technology allows us to develop and produce casting tools in a short time. Castings are machined on wide range of modern CNC machines and robots. Casting tools can be designed on a basis of a sample or a technical drawing.

If it is necessary, we can protect products against corrosion with an anti-corrosion coating – painting, galvanizing or hot-dip galvanizing.
