Green Sand Additives, 3rd Edition
Included in this guide are the effects of proper and improper use of additives, listing indicative tests and typical observations. Most of the individual ingredients incorporated into preblended mixtures are addressed, as well as carbons, cellulose, cereals and starches, chemicals, clays, refractories, and water. New to this edition is a sub-chapter on dust collection.
This third edition of the Mold & Core Coatings Manual was prepared by the AFS Mold-Metal Interface Reactions Committee. It was originally published in 1982 and revised in 2000. This edition of the popular book updates information on coating selection, process control of coatings, manufacturing and control testing, application and drying methods, test methods, and adds a chapter on coating-related defects. The chapter on health considerations had been revised and updated with the most current information. A bibliography and glossary also are in this edition.
This full-color wall chart is intended to aid in classifying coating defects in metal castings, suggest potential causes and offer various solutions. It will prove to be an invaluable resource in helping to produce consistent high-quality castings. The chart is organized with 12 full-color photos of the coating defect or imperfection, definition, possible causes, and potential solutions. The defects or imperfections included are: Cratering/Fish Eyes/Bubbles, Brush Mark, Excess Coating, Scabs/Inclusions, Orange Peel, Tear Drops, Erosion, Veining, Metal Penetration, Coating Retention, Blows (Gas Defects), and Spalling. In addition, a QR code is on the chart, which, when scanned, will link the user to additional resources on coatings-related defects.
Sand processing is a unique combination of art and science. Most generally accepted principles of sand control have been shaped by a combination of practical experience and scientific study. Principles of Sand Control is based on both fundamental and current metalcasting practices, making this a publication that is practical for the novice as well as the experienced individual.
The Aluminum Permanent Mold Handbook was created to fill the need for information on the increased application of permanent mold castings. These expanded casting applications are a direct result of advances in the process technology and of the enhanced knowledge of this process by today's design engineers. Members of the AFS Aluminum Division Technical Committee 2E, Permanent Mold Practices, were responsible for the development of this handbook. Foundry personnel, design engineers, and process engineers will benefit from this handbook. Highlights include alloy selection; process variations with typical parts applications; manual, semi-automated or fully automated castings processes; casting defect causes and remedies; and computer simulation.
