Deep Draw forming with conventional tool and die technology is the stretching of sheet metal stock, 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 pressure between two tool surfaces; normally in a ring shape. One ring is the blank holder and the other is the forming die. The plug passes through the blank holder ring into the cavity of the die ring at the desired depth to achieve the end shape. The dimensions on the part are set based on the shape of the plug, the shape of the die, and how deep the part is drawn. For fatigue strength and applications where uniform metal thickness is critical, drawing and hydroforming are preferred over metal spinning. Like hydroforming, conventional draw forming applications are typically enclosures, cans, cups, canisters, containers, covers, motor shrouds, tanks, vessels, chambers, enclosures, domes etc.

Deep drawing and press forming are two essential processes used in the manufacturing industry to produce complex shapes and designs from sheet metal. Press forming involves compressing a sheet of metal into a specific shape using hydraulic or mechanical power. Deep drawing, involves creating a three-dimensional shape, such as a vessel, chamber or dome, from a flat sheet of metal by pulling it into a forming die with a punch. It is commonly used to produce pharmaceutical containers, automobile parts, Food Processing Equipment, Lighting, Bulk handling Equipment and more. Deep Drawn and Press formed parts can be made from a range of materials such as aluminum, stainless steel, copper and brass.

Both Deep Drawing and Press Forming require precision and experience to achieve the desired result, and Toledo Metal Spinning has over 90 years of expertise. 

In summary, while both deep drawing and press forming are distinct techniques, they are critical processes that allow for the mass production of intricate and intricate designs using sheet metal.

Our presses also offer another unique service as we can use them to create “Pre-forms” or preliminary part formings that will be used to ease the metal spinning process and allow us to achieve more complicated forms with metal spinning and ensure the highest quality part using this process. This helps us minimize the material strain in the metal by utilizing the best aspects of each process. At TMS, we combine deep drawing and metal spinning to produce parts that deep drawing alone or spinning alone might not be able to do.

Parts can be created utilizing sheet or tube forms of aluminum 1100-O, 3003-O, and 6061-O, carbon steels 1008-1020, CDA 655 copper, 655 and 718 inconel, and stainless steel series 304, 304 DDQ, 316, 410, and 430. Our state of the art equipment utilizes a punch force of up to 368 t and a pressure of 10 ksi to create custom parts, achieving tolerances of +/-.020 in and +/-.030 in., with +/-.010 in., in special cases. The maximum punch diameter is 12 in, blank diameters can reach 15 in, and flange diameters are also up to 15 in. Hydroform drawn parts are possible in sizes of up to 7 in. in height.

Once the part is drawn, if it needs a hole, a stamped feature, welded fitting, or a metal polish specification you can also increase the value of your TMS drawn part while saving time and money by taking advantage of our secondary stamping, spin forming, machining, welding, and metal finishing operations.

Deep drawing is an incredibly useful process that facilitates the creation of parts whose height exceeds their diameter or cross-sectional area. This type of component is highly valued across a range of industries and applications, but requires a particular set of manufacturing techniques to produce effectively. Deep drawing is typically measured as a ratio between the part’s depth and diameter, and the process can be tailored according to the type of material being used, as well as the desired form. Toledo Metal Spinning Company specializes in, but is not limited to, the deep drawing of stainless steel. In particular, grades 304 and 316, which are highly corrosion-resistant and offer excellent formability. The deep drawing process is incredibly versatile and offers numerous benefits over alternatives such as metal spinning. With deep drawing, it is possible to create much deeper, more complex forms at larger volumes and with minimal labor costs. Additionally, since deep drawing eliminates the need for welding or joining multiple pieces, it reduces the risk of complications related to corrosion.

Ensuring that the drawing process proceeds smoothly requires an understanding of the impact that material properties can have on the overall outcome. This is because certain types of materials, especially those that are brittle or non-ductile, can pose significant challenges when attempting to draw them at ambient temperatures. Unfortunately, even materials that are otherwise strong and durable, such as tempered or strain-hardened steels and aluminum, often fail when subjected to the stresses of the forming process. To mitigate these issues, experts have identified Draw Quality (DQ) and Deep Draw Quality (DDQ) steels, stainless steels, and ‘O’ condition Aluminums as the most suitable materials for drawing. These materials possess a more stable structure, smoother grain, and higher elasticity, allowing them to be more easily formed while also reducing the wear and maintenance requirements over time. Therefore, it is of utmost importance to use formable tempers and Draw Quality materials to ensure optimal performance and a positive end result in the drawing process.

304/LGood – Lowest cost of high quality deep drawing stainless steel material. The high nickel content allows for good deep draw working.

Mechanical Properties*: Elong = 60%, Yield 34/30 KSI, Tensile 85/75 KSI
316/LGood – More corrosion resistant than 304 grade due to the addition of molybdenum with the same higher levels of nickel, thus allowing for it to be an excellent deep drawing stainless steel.

Mechanical Properties*: Elong = 60%, Yield 30 KSI, Tensile 75 KSI
410Low – 400 series, generally lower cost stainless steel than 300 series since there is typically very little or no nickel, is not ideal for extremely deep parts since the lack of nickel reduces stainless steels deep draw ability.

Mechanical Properties*: Elong = 30%, Yield 65 KSI, Tensile 95 KSI
430Low – 430 is similar to 410 with little less strength. Like 410, material is readily available and is less expensive than 300 series stainless steel.

Mechanical Properties*: Elong = 30%, Yield 45 KSI, Tensile 75 KSI
444Low – 444 stainless steel is similar in its ability to form compared to 400 series stainless grades. Uncommon to 400 series, this specialty stainless grade has Molybdenum added with Titanium and Niobium added to stabilize the microstructure. This allows the material to be similarly corrosion resistant to 316, without the cost of 316 due to the lack of Nickel. The low Nickel also allows for excellent resistance due to corrosion cracking to chloride induced stress, which is why SS 444 is frequently used for parts in contact with tap water.

Mechanical Properties*: Elong = 20%, Yield 40 KSI, Tensile 60 KSI
