Sand Casting Process: Advantages and Limitations MetalTek

2020-11-23  The relatively low cost of tooling makes sand casting a process of choice for lower volume needs. Patterns do wear so the material selected for the pattern (typically wood, plastic, or metal) will depend on the expected usage quantity of the part being produced. Though not necessarily cheaper in the short run, the use of machined (or “patternless”) molds may be a cost-effective option for ...

2014-04-02  Green strength and permeability are the two most critical properties of green sand composition. A high strength is needed to prevent mold breakage, but a strength that is too high can cause mold interference which will cause hot tears during solidification and shrinkage. A higher permeability allows gases to exit casting, but a lower permeability will make the surface finish better.
