Casting solutions for energy conversion

New ways for performance and sustainability

Whether we are optimising a material for you or co-developing or further developing a design: the entire range of castings for energy conversion is one focal point of our range of services. After all, raw materials are finite, which is why efficient energy use is becoming increasingly important, both in terms of climate protection and rising energy prices. We respond with cast components that are precisely tailored to your needs, guarantee maximum operational safety for people and the environment and significantly increase plant performance. As a result, we are sustainably and permanently contributing our share of social responsibility.

Our expertise in energy conversion

Wind energy
Ready for the future
and the elements

Early 2000s: Siempelkamp Giesserei produces castings for wind turbines with 4.5 megawatts, which are trend-setting and unique in our industry.

Today, roughly 20 years later, the key figures look even more impressive. Now we are planning and producing highly stressable components for wind turbines up to 12 megawatts for our customers, which have to withstand the forces of the wind and all weathers.

The logistical challenges are constantly increasing due to the extreme geometries and dimensions. We are actively keeping up and offer our wind energy services as an overall concept: the complete production chain through to ready-to-install delivery, transparent project management, one contact partner and maximum safety and quality in terms of production and deadlines – everything from a single source at one location.

We deliver competitive products for your success, e.g.

  • Machine carriers
  • Rotor hubs
  • Center pins
  • Lower decks

Turbine and power plant

Maximum performance
for energy generation

Part of energy is still obtained from fossil raw materials. And since performance, safety and reliability play a central role here, Siempelkamp Giesserei is the right partner for these components. Our compressor housings and compressor components stand for the excellent quality they have to offer as investments of this scale. This means that they can permanently and reliably withstand extreme loads for decades.

Perfect results with specialist

One of the most demanding tasks for our production is the casting of engine blocks and their complex manufacturing process in particular. The aim here is to combine the highly geometric requirements and differences in wall thickness in an optimally controlled cooling process to ensure reliable production. Our special expertise in this process lies in reducing residual stresses in the component. As a result, we provide our customers with the security of high-performance and resilient components, e.g.

  • Drive assemblies and engines for energy supply on cruise ships, navy vessels and merchant ships
  • Engines for energy conversion
  • Emergency power generators, e.g. for power stations, hospitals or shopping centres
  • In-line and V-engines from 6 to 20 cylinders and weighing 3 to 100 t

Nuclear power
for maximum safety

We have been manufacturing casting materials that are used for components in nuclear technology since the 1960s, for example the shielding of the nuclear ship NS Otto Hahn or the CASTOR® cask body.

We have built on this experience and established ourselves as specialists for transport and storage casks. We now manufacture high-tech cast components with a raw casting weight of 80 to 160 t and a wall thickness of up to 600 mm with our technical expertise. These castings are used for the storage and transport of spent nuclear fuel and highly radioactive waste. Casks for lightly to moderately radioactive waste complete our production portfolio.

Precisely executed manufacturing processes, reproducible production and comprehensive testing ensure that our cask casting meets the extremely high requirements for the material and structure. As a result, we can demonstrably guarantee at the highest level that the components are permanently of the highest quality and meet the respective customer specifications.
