GSC, Guidelines for Aluminum Sow Casting and Charging (Third Edition, 2024), deals with casting aluminum into open top molds and charging the resulting sow and cast products into furnaces. Developed by the Association with oversight by its Task Force on Sow Casting and Charging, the guidelines explain the causes of molten metal explosions in this operation and give recommendations for mold preparation and coating, moisture control, casting practice, cooling, handling and storage of sows, and charging procedures. The document is aimed at cast shop operators and their supervisors and is intended to be adapted to conditions at an individual plant.
