Stainless steel is ideal for deep drawing and metal stamping. Press cycle times are faster than metal spinning and welding operations – draw and stamp processes can form one-piece, seamless constructions, meaning the final shape can be formed from a single blank in one or two draws, and can be shipped shortly after being taken off of the press. Deep drawing with stainless steel can achieve deeper draws than other materials like aluminum.
Stainless steel is made up of at least 10.5% chromium, with additions of nickel, iron, and manganese, making it an extremely durable metal equipped with anti-corrosion properties. When exposed to oxygen, the chromium in the stainless steel oxidizes, forming its own protective layer making it highly resistant to moisture and corrosion.
SS 304 is a popular choice due to its excellent corrosion resistance, value, and cost-effectiveness. It is an easy metal to sanitize, making it ideal for kitchen and food processing applications. SS 316 has great properties for chlorine and saltwater or marine environments, allowing it to be utilized with a wide variety of applications.
Stainless steel series that are ideal for forming include 200, 300, and 400.
Galling is a wear that happens when two metallic surfaces slide against each other. This is common in press forming, especially deep drawing. The sliding of the metals causes friction and adhesion that can cause the material to transfer between the two surfaces. The result may be very noticeable or can be microscopic. Typically, the result of galling is noticeable and can be fixed by applying more lubricant to the next blank. Stamping dies are commonly made of high-chromium-alloy steel. Since stainless steel shares high chromium levels, it is important to is extremely important to apply the lubricant for the tooling to last as long as possible.
Typical Past and Present Deep Drawing Uses According to the US General Services Administration
Deep Draw Metal Stamping for Strength and Efficiency The deep drawing sheet metal forming process is a cold-forming metal fabrication process that is conducted in a room-temperature environment. A metal blank is stretched around a die cavity, eventually conforming to the shape of the plug, shape of the die, and the depth of the draw.
Benefits of Forming Deep Drawn Metal Stamped Parts The deep drawing sheet metal forming process is a cold-forming process performed in an environment at or near room temperature, where the metal is permanently deformed into the desired geometry. In this process, the flat metal blank is formed and stretched around a die cavity with a
What is the Trimming Process and How is it Performed? Trimming is a process used to remove excess material to achieve a desired shape, size, and finish, while removing burrs and smooths out sharp edges. To trim a part, it is put on a lathe and processed by a highly skilled metal spinner, or a
The Metal Finishing and Polishing Process The polishing process is a secondary metal fabrication process that is done to create a smooth and shiny surface by utilizing abrasives or chemical treatment, and can be done by hand or robotic automation. The purpose of adding a finish or polish is to improve the appearance by creating
The Benefits of One-piece Constructions At Toledo Metal Spnning Company, we have been forming metals since 1929. With nearly a century of experience, we have mastered a wide range of processes including laser cutting, metal spinning, deep drawing, machining, rolling and seam welding, to build strong and durable high-performance parts. But what truly sets us
The History of Deep Draw Metal Stamping What is Deep Drawing? Deep Draw forming with conventional tool and die technology is the conforming of sheet metal, commonly referred to as a blank, around a plug in either a hydraulic or mechanical press. The edges of the blank are restrained yet allowed to slide by a precise
What is Hydroforming? Hydroforming, or utilizing the hydro-mechanical-press is a metal forming process where complex and structurally sound parts with tight tolerances that can be made from various metals. A water-based fluid force, oil, gas, or a flexible elastic polymer membrane, is highly pressurized up to 10,000 PSi is applied onto a piece of metal,
Clarifying Elements to the Deep Draw Design Process – The Draw Ratio When it comes to tool design, the most important formula is The Draw Ratio, also known as Limiting Draw Ratio (LDR). The formula is: LDR = D / d D = blank diameter d = cup ID or punch diameter This ratio shows
What are the differences of Deep Drawing and Hydroforming? Hydroforming is a specialized Deep Drawing process also known as Sheet Hydroforming. Sheet hydroforming allows various materials to become complex and structurally sound parts. It allows for asymmetrical or irregular shaped geometries, while conventional Deep Drawn parts are symmetrical and uniform throughout the entire shape. Another
