Ask Thomas Engineering Company in Minneapolis: What is the Difference Between Precision Metal stamping and Die Casting?

July 2nd, 2015 · No Comments

There are a number of different ways to fabricate metal parts and each one has unique advantages. Two of these methods are precision metal stamping and die casting. Thomas Engineering Company in Minneapolis, MN has chosen to focus on precision metal stamping, but what exactly is the difference between the two methodologies?

Precision Metal Stamping

In the precision metal stamping process, a flat sheet of cold metal is placed in a stamping die in a mechanical press. The piece is then blanked, pierced, bent, or folded to create the desired component. It’s even possible to perform multiple operations on a part through a process called progressive stamping. Overall, stamping is a very economical way of mass producing a wide variety of parts. The cost per piece decreases as the order volume rises.

Die Casting

Die casting, on the other hand, is a different process where molten metal is forced under high pressure into a steel mold, also known as a die. These dies, which are reusable, can be designed to produce complex components. Die cast components are generally stronger than those created from the precision metal stamping process, as the molten metal’s internal grain takes on the shape of the produced component as it cools. However the die casting process in more involved, and requires more complex machinery, as the metal used must be first melted in a high-temperature furnace.

Thomas Engineering Company specializes in precision metal stamping components that have a thickness between 0.001″-0.125″ for a number of industries, including the automotive, medical, and technology sectors. We use 3D computer-aided design (CAD) software to design the most accurate tools possible.
