Green Sand Casting vs. Investment Casting

Feb 19, 2015

Choosing the right casting process can be critical to successfully producing parts that optimally perform while delivering the best return on investment. When comparing green sand casting with investment casting there are several important concerns. In most cases, the primary advantage of green sand casting is that it costs less per part. However, investment casting can accommodate more complex designs. It produces better surface finishes, thinner walls can be cast and less machining/finishing is necessary. Investment casting becomes more economical with long and repeated casting runs. The right choice depends on the specifications, application and requirements of each individual part. As a rule, if quality, precision and dependability are important, investment casting is worth the cost.
