Which of the following is a limitation when using casting processes?

Using casting processes in manufacturing does have several advantages, such as the ability to produce complex shapes and enable mass production. However, one notable limitation is the potential safety hazards associated with handling hot metals. During the casting process, molten metal is handled at extremely high temperatures, which poses a risk of burns, splashes, and other heat-related injuries to workers. Additionally, there may be risks related to the release of fumes and gasses from heated materials. Addressing these safety concerns is crucial in the design of casting processes and work environments.

The other choices highlight benefits or characteristics of the casting process. While it allows for mass production and is adaptable to complex geometries, these are not limitations but rather advantages that enhance its usability in various manufacturing contexts. Similarly, the applicability of casting to all metals is inaccurate as not all metals are suitable for casting; thus, asserting this as a limitation highlights the selective nature of materials that can effectively undergo the casting process.
