About ZOLLERN
ZOLLERN GmbH & Co. KG, headquartered in Sigmaringendorf-Laucherthal, was founded in 1708 by Prince Meinrad II of Hohenzollern and is one of the oldest family-owned companies in Germany. The company develops and manufactures customised castings, forged parts, steel profiles and drive solutions. The manufacturing processes include vacuum investment casting with EQX and DS/SX technology, open investment casting, aluminium investment casting, sand casting, Croning/shell moulding, ceramic casting, continuous casting, centrifugal casting as well as open-die and closed-die forging, ring rolling, and hot and cold rolling or cold drawing of steel. Materials include, besides steel and aluminium, high-purity copper, copper alloys, nickel-based superalloys and cobalt-chrome alloys. With around 1,800 employees and plants in Europe, North America and Asia, ZOLLERN supplies industries ranging from aerospace, automotive, energy and marine to medical technology and mechanical engineering. Material testing is carried out in the company's own central laboratory.

Materials and Processes
Nickel-based superalloys
In vacuum investment casting (EQX, DS/SX) for turbine components, blades and structural parts in aerospace, energy and defence.
Cobalt-chrome alloys
Investment casting material, among other things, for implants (knee, hip) in medical technology.
Aluminium
Aluminium investment casting for castings, among other things, in automotive and mechanical engineering.
High-purity copper and copper alloys
Open-die forged parts, semi-finished products, flat and round bars for electrical and industrial applications.
Steel (special profiles)
Hot-rolled, cold-rolled, cold-drawn and inductively hardened special profiles, coils and customised finished parts.
Bronze
Casting material of the bronze foundry operating since 1890, the basis of plain bearing manufacturing.
