If you have the need for manufactured metal parts and are using or considering die casting for your parts manufacture, you may be wondering if and when metal stamping is appropriate for your needs. To determine this, it will help to know about both of these metal-part forming processes and how they are typically used, with the advantages and disadvantages of each.
Metal Forming Processes Explained
Die casting is probably the most popular form of metal shaping for today’s manufactured machine parts due to its efficiency and technology good die casting employs to create consistent, quality metal parts. The process of die casting involves forcing molten metal into a closed die of the desired shape of the part, pressurizing the metal as it cools until the part is complete. Metal stamping is a much more primitive, although often still effective procedure, wherein a sheet of metal is delivered into a hydraulic or mechanical press which uses a die and high pressure to shape the metal into the desired parts.
An advantage to metal stamping is that it can be used on both ferrous and non-ferrous materials, while die casting is usually only appropriate for non-ferrous materials. It can also be more economical if the parts being stamped are very simple. The problem is that there is not much flexibility in the shape and thickness of the sheet metal, so the greater the complexity of the part, the more additional components that must be added to the metal stamping process, raising the cost. Metal stamping also produces a lot of waste, as there is a significant amount of unused scrap metal that results from a stamping project, much more than with die casting.
Which Is Better: Die Casting or Stamping?
If you need to produce a high volume of parts with any level of complexity, die casting is usually the correct choice. Because stamping dies are cheaper and usually last the lifetime of the part, and can produce strong parts quickly, some may opt for metal stamping if they have a very large amount of product they need to run off quickly. Of course, if you have a company like Premier Die Casting manufacturing the metal parts for you, the cost of dies is not your concern, and you will still get very fast, effective results, so a metal stamping process is not necessary.
