It is commonly misunderstood that Deep Drawing and Press Forming are two different processes. Many do not know that deep drawing is a type of press forming! Press forming as, a broad term, involves drawing a sheet of metal into a specific shape using hydraulic or mechanical power. Press Forming encompasses not only deep drawing but also hydroforming and stamping, all of which are services offered at TMS.
Press forming metals may include: bending, folding, stretching, or thinning to form the metals into different shapes.
Deep Drawing involves creating three-dimensional shapes, such as cylinders or domes, from a flat sheet of metal. This shape is formed by pulling the sheet into a forming die with a punch. Deep drawn shapes typically have a volume and can be very complex.
Common products formed from deep drawing and press forming include pharmaceutical containers, automobile parts, Food Processing Equipment, Lighting, Bulk Handling Equipment, and more.
The standard deep draw press is built on four posts, which allows for tooling accessibility, as well as easy access for inserting blanks and removal of the final drawn product. Â At Toledo Metal Spinning, our presses are equipped with vertical action drawing, meaning that the shape is formed in one downward or upward motion of the press. This saves time, energy, and money, not to mention that the draw is performed with extreme accuracy. Â
At TMS, we have two AP&T hydraulic presses, each equipped with Human-Machine Interfaces. This allows for our press operators to change the pressure, stroke, dwell time, and other specific functions with a quick push of a button.
At TMS, we have been utilizing our presses for decades, and they have become an integral part of our processing capabilities. We appreciate that our Deep drawn our deep drawn cups, pans, domes, and lids are always very high quality, and our tolerances stay extremely accurate.
Press forming can be highly repeatable and used to quickly manufacture a batch of parts, while being very cost-effective. Running our presses is a great way to capitalize on time saving and efficiency, as opposed to manufacturing them on a lathe or in our welding cells. Our presses can handle drawing thousands of parts a week, if needed!
Greater depth and more intricate configurations can be achieved when the deep draw and spin processes are combined with each other. Each deep drawn part starts with a laser cut blank, which we do in-house at TMS. Our laser cutting technology allows for a burr-free blank that is cut with extreme accuracy. The blank is oiled and inserted into the press. Our advanced draw/spin technology and combination enables us to achieve shapes and configurations beyond the reach of traditional metal spinning methods. Thin parts that are Deep Drawn can be very durable with a very consistent high quality. This distinction positions TMS ahead of others and gives us an advantage, as many metal spinning houses do not have the capability of deep drawing.
The deep drawing process is not as sufficient for small runs due to high tooling costs.
Depending on the profile of the part being formed, manufacturing the tooling typically requires additional time and expense.

A metal blank is stretched around a die cavity, eventually conforming to the shape of the plug, shape of the die, and
Click Here to Learn More 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
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
Click Here to Learn More 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
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,
