How to reduce the cost of your casting
A lack of casting knowledge is at the root of nearly every cost driver for large castings. To complicate matters, even if you have general knowledge or experience in casting, every foundry uses different processes. What works to reduce cost in one operation can drive the cost up in another. Even if you have general…

One basic principle in reviewing a casting design is Geometric Dimensioning & Tolerancing (GD&T). This system defines and communicates engineering tolerances through symbolic language on engineering drawings. It explicitly describes the part geometry and allowable variations. Using GD&T helps the customer’s design engineer, the supplier’s manufacturing engineer, and quality inspectors to reach consensus on a…
