HIGH PRECISION
Precision castings for complex requirements
Investment casting
Investment casting produces sophisticated metal components with high dimensional accuracy and excellent surface quality. The process allows for maximum design freedom whilst reducing material usage and minimising machining requirements.
Customer benefits: Design engineers benefit from a high degree of design freedom and the ability to produce complex, functionally integrated components. Purchasing managers benefit from low total cost of ownership, reduced post-processing and high process reliability.
What is investment casting?
Investment casting, also known as lost-wax casting, is a high-precision casting process for producing complex metal components with tight tolerances and excellent surface quality. In this process, a ceramic mould is produced using wax models that can be melted away, and is then filled with molten metal.
The process is particularly suitable for components made of steel, stainless steel and special alloys where complex geometries, delicate contours, high dimensional accuracy and a high-quality surface finish are required.
As the finished part closely matches the final contour, material usage, post-processing and machining costs can be significantly reduced. Investment casting is therefore an efficient solution for technical castings in small-batch, medium-batch and series production.
Benefits of investment casting
- High dimensional accuracy and attention to detail
- Excellent surface quality
- Complex geometries and delicate contours
- Wide range of materials, e.g. steel, stainless steel and special alloys
- Reduced post-processing thanks to near-net-shape production
- Cost-effective production of sophisticated castings
- Suitable for functionally integrated components
Typical applications
Investment-cast components are frequently used in mechanical engineering, vehicle manufacturing, medical technology, process engineering, valve technology, pump technology, building services engineering, precision engineering and in high-quality industrial applications.
