Despite their importance, metal enclosures have certain drawbacks. Weight: Metal enclosures, particularly those made from heavier materials like stainless steel, can add significant weight to a product. This may not be an issue for stationary machinery, but it can be problematic for portable devices or equipment. Corrosion: While certain metals are resistant to corrosion, others, like carbon steel, are susceptible, especially when exposed to moisture and certain chemicals. Machining difficulties: Machining complex shapes from metal can be difficult and costly, particularly for thicker materials. Cost: While metal enclosures are durable and long-lasting, they can be more expensive to manufacture compared to other materials, such as plastic. Thermal conductivity: Metal enclosures can conduct heat, which can be a disadvantage in certain applications where heat dissipation is a concern.
