How Does the Stainless Steel Stamping Process Work?

Den stainless steel stamping process börjar med en blank piece of stål sheet. This blank is placed into a stämpling press, where a verktyg, often called a stans, applies force to shape the metall. The process can be simple, involving a single stans and die set, or complex, requiring multiple stages and Verktyg for operations like bending, coining, and djupgående ritning.

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 stämpling process not only met the tight dimensional tolerances but also ensured the part’s strukturell integritet.

What Types of Stainless Steel are Used in Stamping?

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

Grade 304 is a popular austenitic stainless steel known for its excellent formability och korrosionsbeständighet. It’s commonly used in kitchenware and food processing utrustning. Grade 316, another austenitic type, contains molybdenum, which enhances its resistance to pitting and crevice Korrosion in chloride environments, making it suitable for marine applications.
