What Type of Parts are Good Candidates for Sand Mold Casting?
Firstly, the best types of parts for sand mold casting are metals, because the process can be harsh and is best if used with more durable substances. There are also a variety of types of metals that can be used in sand mold casting. Harder metals such as steel and iron ore are great for this as well as precious metals that are more malleable or softer. All in all, parts that must be mass produced, yet intricately designed are great for sand mold casting. As a result, the best candidates for sand mold casting are very design oriented parts that cannot merely be stamped out of a machine, so they must be molded and poured into this caste individually.
Designing Parts for Sand Mold Casting
Designing parts for sand mold casting can be tricky. The first requirement is that a pattern must be able to be made of the part, so that it can be molded into a cast. Secondly, the casting must be made durable enough to survive the process. Both cores, which take longer to cool, and the outer parts must be able to be popped out of the mold in order to form a complete recreation of the mold. The cast must be open enough for the liquid metal to flow evenly and fill the casting to form a complete finished product.
Sourcing Sand Mold Casting
Unlike most other metal working processes, sand mold casting is something that not only should be done by a professional, but it should be done in a shop or area that has the correct tools. Firstly, the sand mold casting worker must have the appropriate knowledge of the correct sand to clay mixture for the cast in order to ensure that the metal does not stick to the caste. So, finding a professional to ensure that the work is done properly should not be difficult.
