The production of your castings.

From the pattern to the aftertreatment: fast and reliable.

Starting with the creation of the pattern through to the creation of core boxes and the production of customised small, medium and large series, we tailor our services to your requirements. This involves processing grey cast iron and ductile cast iron using the sand casting or centrifugal casting method. Our own pattern construction department, various moulding plants with different box sizes and a hand moulding shop for smaller series and larger fittings mean that we can react flexibly to your needs. To guarantee the longevity of the products, we also offer liquid paint, epoxy or enamel for optimum surface protection, depending on the area of application.

Pattern construction.

Der erste Schritt im Gießverfahren.

The first step in the production of a casting is the creation of a pattern. We manufacture patterns, as well as sprue and riser systems, made of metal, plastic or wood depending on the size and number of pieces. Accurate work and regular inspections during the production process are essential – the pattern is, after all, the basis for all further production steps.

Melting shop.

Metallurgical plants for the jobbing foundry.

In the jobbing foundry at its two plants in Karlstadt and Laufach, Dueker has a range of melting units, heat retaining furnace and treatment equipment, which are used for different stages in the moulding process. Alongside a hot blast cupola furnace, this also includes induction/crucible melting furnaces, induction/channel-type heat retaining furnaces and induction/casting furnaces. Dueker also offers treatment using wire winding or tundish ladling.

Core production.

Production of casting cores for iron casting.

We use various core manufacturing processes with inorganic and organic binders depending on the requirements for the casting cores for iron casting. We offer different core manufacturing options, including resol CO2, cold box, croning, furan resin and water glass CO2. The volume of the casting cores generally ranges from 2.5 to 80 l. In the hand core moulding plant, there are virtually no upper limits. We use coating materials to improve the surface and modify the heat transfer between liquid iron and core sand.

Moulding process for castings.

Products take shape.

The moulding process involves the creation of the castings. We offer various methods that deliver the best possible results depending on the area of application and the target specifications. Key differences include the required box sizes, the weight of the castings and the speed of production. Details can be found in our custom casting brochure.

Casting aftertreatment.

The final touch for the castings.

Depending on the target specifications, there are additional processing steps after the moulding process. For example, raw casting aftertreatment, heat treatment, pressure testing as well as mechanical processing and surface protection.
