Casting is one of the oldest manufacturing techniques. However, there are several modern advancements in technology that have resulted in a number of casting techniques and methods. In this blog, we will deal with two types of castings that are useful to produce a range of finished products including aerospace parts, mechanical devices, construction supplies, etc: Sand Casting & Die Casting. Castings that enable molten metal to be poured in an exclusively designed mould to produce various forms and shapes. Let’s restrict to two processes alone for simplicity namely Sand Casting & Die Castings:
- Sand Casting:
This process usually involves the use of silica-based or synthetic sand that can be used to produce a smooth moulding. This is a useful option as it can be deployed for both ferrous as well as non-ferrous metals. It, however, is a brilliant process for casting a moderately low-tearing capacity and a comparatively moderate degree of flexibility during the process of cooling. There’s also a downside to it: it creates a rough finish and accuracy is low. Automobile parts and engine blocks are normally made via sand casting.
- Die Casting:
This process is applicable for moulding non-ferrous metals and alloys subjected to high pressure to produce uniform designs. Metals including copper, tin, zinc, etc are the primary materials. The mould is subjected to lubrication so as to regulate the metal ejection as well as temperature. Once injected, the metal is subjected to solidification under extremely high pressure. After the process, the component is extracted out of the die casting, thereby helping it achieve a high level of accuracy. If you are looking for industrial casting process, die casting is the most suitable method.
