Precise solutions for demanding applications

Stainless steel investment casting

Stainless steel investment casting is a high-precision process for manufacturing complex components made of stainless steel. It is primarily used in sectors such as the automotive industry, medical technology, food industry and aeronautics. A combination of outstanding precision, high material strength and corrosion resistance makes stainless steel investment casting a preferred choice for numerous industrial and technical applications.

Advantages of stainless steel investment casting

Stainless steel investment casting combines numerous advantages compared to other casting processes.

  • Precision and attention to detail: The wax pattern and ceramic mould make it possible to create high-precision structures and complex geometries.
  • Variety of materials: Stainless steel alloys offer customised combinations of corrosion resistance, hardness and temperature resistance.
  • Efficiency and Sustainability: The process minimises material loss as excess stainless steel is recycled, while the reusability of wax reduces waste.

Applications for stainless steel investment casting

Stainless steel investment castings are used in numerous sectors:

  • Automotive industry: High-precision components such as exhaust manifolds, turbocharger wheels and transmission parts are often cast from stainless steel. These components enhance the efficiency and service life of modern vehicles.
  • Medical technology: Due to its biocompatibility, stainless steel is ideal for surgical instruments, implants and casings for medical devices.
  • Food and pharmaceutical industry: In these areas, stainless steel components score highly thanks to their hygienic properties and resistance to chemical influences.
  • Aerospace: The lightness and strength of stainless steel make it perfect for components that have to withstand high levels of stress.

 

Innovative manufacturing technology

Stainless steel investment casting is an innovative manufacturing technology that meets the highest standards of precision, material quality and sustainability. This process makes it possible to produce complex components that are optimised for use in a wide range of sectors. Whether for demanding industrial applications or delicate technical products, stainless steel investment casting is the first choice when it comes to quality and versatility.

Stainless steel investment casting in detail

The first step in the investment casting process is to create a precise wax pattern that reflects the exact shape of the future component. This wax pattern is mounted on a so-called casting tree in order to produce several components in a single step. The casting tree is then repeatedly dipped into a ceramic liquid and sprinkled with ceramic sand to create a thick, fireproof shell.
Once the shell has hardened, the wax is melted out by heating, creating a hollow mould. This mould is filled with liquid stainless steel that has been heated to high temperatures to ensure optimum flow properties. After the metal has solidified, the ceramic mould is removed and the castings undergo careful post-processing, such as grinding, heat treatment or surface finishing. This process guarantees the highest levels of precision and quality.

How environmentally friendly is stainless steel investment casting?

The process is particularly resource-efficient. Wax and stainless steel residues are recycled, reducing waste to a bare minimum.

Which sectors particularly benefit from stainless steel investment casting?

From the automotive and food industries to aerospace - investment casting is in demand wherever precision, durability and efficiency are important.

Which stainless steel alloys are suitable for investment casting?

Depending on the application, alloys with different properties are used, such as stainless steel for corrosion resistance or heat-resistant variants for extreme temperatures.

Why choose stainless steel investment casting?

Stainless steel investment casting provides manufacturers with a cost-effective way to produce complex components in large quantities and consistent quality. The process is especially distinguished by its flexibility in adapting to individual requirements. Whether for small precision parts or larger assemblies - stainless steel investment casting constantly delivers outstanding results.
