GMB Giessereimaschinenbau GmbH, Bernsdorf
History ;
1788 Count of shipowners from Koenigsbrueck founded in Berne Village, the " iron works" with an iron hammer and a melting furnace for smelting of bog iron from the environment.
1990 Foundation of Foundry Engineering GmbH, based in Bern village , with the following production program :

• Foundry equipment
• Entstaubungstechnik
• Steel construction groups

As of 1992, steel structures, tanks and pipeline construction are included in the production program .
Production is delivered on export companies abroad.
Project planning, design , supply and installation of :
Containers , silos and pipelines ( dust collectors , industrial water pumping systems ) for the foundry and building materials industry
Pipe shafts for pumps
Special equipment for mining
Ship Structural constructions
Steel chimneys
Crane rails , steel structures
and the processing of stainless steel
Our Service :
Specialist for water balance technique according to WHG
Scale and rust from metal sheets and profiles
Priming and painting
Rolling, folding, CNC flame cutting and sawing.

We are welding and designing structures in the full range of materials, such as

• Heat resistant steels (C 22.8, 13CrMo44, 10CrMo910, P91,...)
• Austenitic and Duplex steels ( 1.4571, 1.4462,...)
• Nickel-based alloys (2.4602, ..2.
• Non-ferrous metals (aluminium, magnesium, copper, CuCrZr,...)
• High-melting metals (tungsten, molybdenum,...)
• Material combinations (titanium/platinum, steel/copper, molybdenum/steel, silver/copper, high-grade steel/heat-resistant steel, 42CrMo4 with St 52-3,...)

We are hardening the surface layer of steels with a carbon content >= 0.3%. Electron beam hardening with a surface penetration depth of 0.3 to 1.5 mm. Hardening to some 60 HRC according to material grade. Quenching fluids are not required. For quenching the temperature difference between the surface exposed to electron beam and material behind it is used. Materials like

• 42CrMo4
• C 45
• GGG 60

are our standard.
