CASTFAST supplies customized aluminium castings for a wide range of applications – from prototypes to series production. Depending on the requirements, we rely on the appropriate casting process: 3D sand printing for maximum design freedom and short development times, classic pattern technology for economical series, lost molds, investment casting for high detail accuracy or gravity die casting for dimensionally stable and mechanically resilient components.
You are welcome to ask for these anyway – we will check the feasibility individually.
