Die Casting vs. Metal Stamping: The Main Differences

Whenever you have to manufacture metal parts, you start wondering whether and when the metal stamping die is the best one to meet your requirements. Knowing this helps you understand the parts of metal-forming processes, how they are used generally, and their own set of pros and cons.

Metal Forming Processes Explained:

Whenever you are taking the metal in its solid or molten form, it may transform into its specific shape. There are various ways the manufacturer completes this task with each of its distinctive applications and benefits.

The two instances of metal forming processes standard across manufacturing operations are the metal stamping and die casting processes. Automotive metal stamping companies use die casting or metal stamping processes depending on your needed parts.

Die Casting

Die casting is the most common type of metal shaping process, mainly due to the technology and efficiencies employed in creating top-quality metal parts.

Metal Stamping

Metal stamping die is much more primitive, although it is the most effective process. The sheet of metal is delivered into their mechanical or hydraulic presses using high pressure and die in shaping the metal into their desired parts. But, metal stamping involves much more than the processes alone; it even involves blanking, flanging, embossing, and bending.

Die Casting Pro and Cons

Whenever you are looking for a general higher volume of parts with every level of complexity where die casting is the best choice made by the automotive metal stamping companies, you will have a few scrap metals left behind by die casting. However, it is relatively more minor than you can recycle. Die casting is a highly efficient way to form metal. Additionally, whenever anything is done by die casting, it is more likely to align well to the specifications and requirements for surface finishes.

You should choose the die-cast process whenever you have to make thin-walled metals. Generally, die-cast tooling is the most efficient and cost-effective way to help reliably produce smaller and larger elements.  

One of the primary cons involved in die casting is the need to use nonferrous materials, which is a significant drawback depending on its applications. Furthermore, due to the pouring processes, the products have inconsistencies in their densities from air becoming trapped in the die. Finally, die casting might not become the ideal choice for the low production run due to the expense and time involved in creating dies.

Metal Stamping Pros and Cons

Since the stamping dies are cost-efficient, lasting the part’s lifetime, a few may choose metal stamping dies whenever they have a more significant amount of product they wish to run off quickly. Sheets of ferrous or nonferrous materials are used for metal stamping processes. It works well for high or low production runs or consistent yields of better quality parts. The process even offers a greater level of automation. 

More tools are required whenever you are creating complex products with the help of metal stamping. More the complexity of the tools, the more expensive it is, as metal stamping might not be the cost-effective option. The issue involved here is that there is not much flexibility in the thickness and shape of sheet metal.
