When it comes to forgings, there are many different types. Two of the most popular types are open-died and closed-died forgings. Before selecting which production method is best for your next project, you need to know what each process does and their differences.
Also known as free forging, open-die forging involves deforming a piece of metal between multiple dies that do not enclose the metal entirely. This allows the dies to hammer and stamp the metal into the desired shape. Open-die forging usually requires secondary machining and cannot create pieces with complex parts.
Closed-die forging, also known as impression forging, is very similar to open-die forging but differs in one key area. Instead of using dies that don’t entirely enclose the metal, closed-die forging involves dies that completely encapsulate the molten metal. This leads to parts that can be very complex while also being small. This method does not require any secondary machining too, which lowers the overall production cost.
At the end of the day, it boils down to what you need the most. Both methods have their advantages and disadvantages. If you are trying to create a complex machine part or something that you don’t want to pay to have additional machining done, closed-die forging is for you. If you are trying to create a high number of products and need to do so quickly, maybe open-die forging is for you.
