Die Casting Mould Vs. Stamping Which To Use

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 Parts.
