The surface finish of middle casting processes is a key factor in their versatility and wide range of applications. By producing castings with a good surface finish, middle casting processes can meet the demands of a variety of industries, from consumer products to electronics to medical.

In addition to the above, the surface finish of middle casting processes can also be improved through the use of post-casting processes, such as machining, grinding, and polishing. These processes can further improve the surface finish of castings, making them suitable for even more demanding applications.

Cost-effectiveness

Cost-effectiveness is a key advantage of middle casting processes over precision casting. Precision casting processes, such as CNC machining and EDM, are typically more expensive than middle casting processes, such as investment casting, die casting, and centrifugal casting. This is because precision casting processes require more specialized equipment and skilled labor.

• Lower tooling costs: Middle casting processes typically have lower tooling costs than precision casting processes. This is because the tooling for middle casting processes is simpler to design and manufacture.
• Higher production rates: Middle casting processes can typically produce castings at higher rates than precision casting processes. This is because middle casting processes are more automated and can produce multiple castings at the same time.
• Reduced material waste: Middle casting processes typically produce less material waste than precision casting processes. This is because the castings produced by middle casting processes are closer to the desired shape and size, resulting in less material being removed during post-processing.

The cost-effectiveness of middle casting processes makes them a viable option for larger production runs. This is because the lower tooling costs, higher production rates, and reduced material waste can lead to significant cost savings over the long term.

Versatility

The versatility of middle casting processes is one of their key advantages. Middle casting processes can be used to produce a wide range of castings, from small to large, and from simple to complex. This is due to the fact that middle casting processes use molds or dies, which can be designed to create castings of various shapes and sizes.
