The Core of the Matter
Pöschel GmbH Metallguss, founded in 1994 and now run by the second generation, is a specialist in the design, development and production of demanding castings in aluminium and copper-based alloys. At the Solingen site, permanent mould castings are produced on 800 m² of production floor space – machine-cast on gravity die casting machines or cast by hand, in each case with or without sand cores – as well as sand castings for complex geometries with bores and intersecting contours. Using steel and sand cores, thin-walled, pore- and shrinkage-free mouldings are also produced reproducibly. The service spectrum includes materials and design consulting, solidification simulation and finite element analysis, prototyping, heat treatment (T1, T5, T6, T7 per DIN EN 1706), ready-to-install CNC machining, and powder and KTL coating. Customers come from laboratory technology, medical technology, energy technology, mechanical engineering, electrical engineering and mining; lot sizes range from one-off parts to medium series of around 10,000 pieces. The quality management system is certified to DIN EN ISO 9001:2015.

Materials and Processes
AlSi12 (230)
Good castability and tightness for thin-walled, complex housings, e.g. in laboratory and medical technology.
AlSi0,5Mg
High-conductivity alloy for contact holders in energy technology, with targeted heat treatment to increase electrical conductivity.
AlSi8Cu3
Strength-oriented alloy for pressure-tight, shrinkage-free flange parts in mechanical engineering.
Copper-based alloys
For components with special requirements for conductivity and heat transfer.
Brass (cast-in bushing)
Cast-in bushings integrate bearing functions directly into the aluminium component.
Permanent mould casting (machine and hand casting)
With or without sand core, for pore- and shrinkage-free parts from one-offs to medium series.
Sand casting
For complex geometries and contours with bores via steel and sand cores.
Heat treatment T1/T5/T6/T7 (DIN EN 1706)
Tempering by solution annealing, quenching and artificial ageing; T7 for maximum electrical conductivity.
CNC machining
Dimensionally accurate, ready-to-install production incl. thread tapping, turning of bearing seats and attaching rivet pins.
Powder coating
Protective surface coating of the castings.
KTL coating
Cathodic dip painting for uniform corrosion protection.
