How Does the Stainless Steel Stamping Process Work?

O stainless steel stamping process começa com um em branco piece of aço sheet. This em branco is placed into a estampagem press, where a ferramenta, often called a soco, applies force to shape the metal. The process can be simple, involving a single soco and die set, or complex, requiring multiple stages and ferramentas for operations like bending, coining, and desenho profundo.

There are various type of stamping processes:
Progressive Die Stamping: This method uses a series of stamping stations. Each station performs a different operation on the metal sheet as it moves through the press, progressively shaping the part.

Transfer Die Stamping: Similar to progressive die stamping, but the part is transferred from one station to the next by a mechanical transport system.

Four-Slide Stamping: Also known as multi-slide stamping, this technique uses four tools to shape the workpiece. It’s particularly effective for creating complex parts with multiple bends.

Fine Blanking: This specialized process produces parts with very tight tolerances and smooth edges, often eliminating the need for secondary operations like deburring.

During my early years in the field, I witnessed firsthand the precision that stainless steel stamping could achieve. One memorable project involved creating small, intricate components for a communication device. The estampagem process not only met the tight dimensional tolerances but also ensured the part’s integridade estrutural.

What Types of Stainless Steel are Used in Stamping?

Vários types of stainless steel are employed in the estampagem process, each offering unique properties suited to different applications.
