Step 1: Melting and raw materials

Melting furnaces are indispensable elements in the die casting process. They enable the precise melting of casting materials and alloys, which in turn form the basis for high-quality products. Advances in technology have led to improved energy efficiency and precise temperature control. At the same time, melting furnaces contribute to sustainability by promoting the recycling of metals and reducing the use of primary resources. In an increasingly resource-conscious world, melting furnaces thus play a crucial role in the production of high-quality products.

Choosing the right casting material and the right alloy is crucial for the quality of the end products in die casting. Aluminium alloys are particularly widespread as they offer an ideal combination of low weight and high strength. Magnesium alloys are ideal for applications where low weight and good mechanical properties are required. Zinc alloys are characterised by their corrosion resistance.

Modern melting and holding furnaces are equipped with advanced technology to ensure precise temperature control during the melting process. The use of induction or gas heating enables efficient heating of the cast materials, resulting in improved energy efficiency. The holding furnaces ensure that the molten metal is always kept at the optimum temperature during the casting process to produce high quality castings.

An important aspect of the casting industry is the recycling of metals. Melting furnaces play a key role here, as they enable the melting of recyclable metals. By using recycled metals as a secondary component in the alloys, the consumption of primary resources can be reduced. This promotes a closed cycle and contributes to sustainability in the casting industry.
