Casting Process Comparison

Casting processes are compared to show the relative capabilities with respect to many considerations such as:
• Type and grades of metal to be cast
• Weight and size of castings to be manufactured
• Surface finish and the cast condition desired
• Acceptable level of porosity that can be obtained
• Complex shapes that can be cast in one piece without further joining processes
• Dimensional accuracy desired
• Thickness of casting wall
• Allowable draft required
• Average tooling cost
• Typical order quantities

After selecting a casting process, further selection of equipment may influence the cost due to equipment costs, productivity, quality level, safety, and environmental concerns. Ultimately the final selection of a casting source depends on the technical considerations, economic considerations and equipment/infrastructure that is available within the selected manufacturing facility.
