ALUMINUM CASTING PROCESS COMPARISON CHARTS Copyright 2002 Austin Group, LLC. All rights reserved. A Qualitative Comparison of Several Competing Processes for the Production of Aluminum Castings The following charts are intended to provide a relative guide to compare various aluminum casting methods. It is important to note that, the actual costs and casting results will vary significantly for any given project. The complexity of the part, the number of cores or pulls, the engineering and design time and customer requirements will all have a significant impact on the cost to produce a part with any of the compared methods. An attempt to provide specific comparison data for a given part would be highly sensitive to that particular part. Therefore, a composite of existing source data including foundry results, professional society literature, equipment manufacturer comments and personal experience was used to generate the comparison charts. Foundries, foam molders and tool builders contributed to the collection of the data. Copyright 2002 Austin Group, LLC. All rights reserved.
