About investment casting
This technique is also known as precision casting or silica sol casting and is one of the oldest casting techniques.
This technique offers unlimited freedom in design and material selection. Products can range from a few grams to more than a hundred kilograms. Specific applications can be found in the automotive and process industries.
By producing wax models with water-soluble or ceramic cores, it is possible to realize complex internal structures in castings. Due to the high precision of this technique, it is highly suitable for converting conventionally produced products into castings, requiring minimal post-processing and allowing for a reduction in the weight of the final product.
Investment cast components can be easily ground. Due to the low investment in molds and startup costs, it does not matter with this technique whether it concerns single units or hundreds of thousands. Through the possibilities of 3D printing wax models, we can save on the investment in molds.
Advantages
– Low tolerances
– Thin wall thicknesses are possible
– Low surface roughness
– Complex designs can be realized without draft angles
– Small markings can be cast very clearly, such as text or logos
– Suitable for a wide range of materials
