A Design Study in Aluminum Castings - GM Cylinder Block                                          

Quality Assurance

The quality targets (performance and production) for the cylinder block require a flaw-free, controlled microstructure, precision dimensioned casting.
Precision Metal Pour in GM Plant

Quality is engineered into the cylinder block through the entire  design and production process.  

  • Engineered design for performance and manufacturability.

  • Precision process control at each production step --  EPS bead preparation, pattern forming and assembly, cluster coating, sand fill, melting, casting, cleaning, heat treating, and machining.

  • Detailed measurement  and recording of critical properties (dimensions, weights, pressure tightness, hardness, etc) at the different production steps
