Excerpt from the December 2018 Engineering Product Design article.
Green sand casting is the most versatile among the manufacturing methods that enables manufacturing of very detailed and complex parts from various metals and their alloys.
A casting design would be useless unless the design can be made in the foundry, satisfying all the functional requirements within budget. The cost effectiveness of the process depends highly on the design as this reflects the final cast. The decisions made during the design changes would make a big impact on the cost and some of the disadvantages of sand casting can be avoided by designing the part to suit casting. However, there are key sand casting design guidelines to keep costs down. Engineering product designers should understand the reasons why some of these techniques are used and consider those during the design stages of the cast.Read More
