Casting

Low-Pressure Casting Process

The low-pressure casting process is characterized by particularly uniform material distribution and high process reliability. The aluminum melt is fed from below into the closed mold via a riser tube using precisely controlled gas pressure. The pressure is kept constant throughout the entire solidification phase to compensate for volume shrinkage through controlled feeding. The desired directional solidification from top to bottom is supported by optimized cross-sectional geometries already at the design stage. After casting, all blanks undergo fully automated X-ray inspection for quality assurance. Depending on requirements, this is followed by T6 heat treatment and subsequent tempering.
