Key Benefits of the Deep Drawn Forming Process
Leave a CommentDeep drawing is a metal forming process using a punch and die to create three-dimensional, round or rectangular, hollow part features and products from flat sheet metal. Deep drawn parts are defined as those in which the depth of the hollow exceeds the radius or length and width of the flat blank shape. Parts are designed so that the thickness of the material is approximately uniform throughout after it is formed. ZERO Manufacturing specializes in deep drawn forming for durable, high-quality protective metal cases and enclosures.
There may be multiple ways to form cases and enclosures from sheet metal; however, the deep drawing process offers several benefits that result in a better product. Learn more below.
The Benefits of Deep Drawing
For many applications, deep drawing has many advantages for both the production process and the final product. Some of the key benefits of this method include:
High Production Speed
Deep drawing is fast because automated presses punch one blank after another with little time between cycles. Once tooling is set up, large quantities of parts can be drawn in rapid succession, for short lead times.
Enhanced Strength and Durability
Deep drawn metal goods are stronger than those produced through other methods because the stamping and drawing processes harden the metal, giving it better structural integrity. What’s more, drawn parts do not have seams, so they are made from contiguous material and have few weak points. This is ideal for deep drawn containers that will carry fluid, cases that must withstand impact, and aerospace components that will face heavy stress.
Cost Efficiency
Deep drawing is cost-effective for high-volume orders and standard shapes. Once the initial tooling is complete, goods are produced with less labor than other types of sheet metal manufacturing. Because goods are made from blanks that are accurately pre-sized, there is also very little waste. The speed of production further streamlines costs.
Precision and Consistency
Deep drawn parts are formed with specialized tooling that is designed for the application, so the resulting parts are highly accurate. And because the same tooling is used over and over, and the metal blanks are aligned in an automated press, there is very little variation from part to part and minimal scrap. Tooling is manufactured with the aid of computer modeling and precision machining, so it’s possible to achieve the dimensions specified on the part print to within tiny fractions of an inch. This ability to hold tight tolerances throughout a production run means part fit and function are improved.
Complex Geometries
Drawn parts are complex shapes with specific diameters, radii, and curvatures. The deep drawing process and specialized tooling create these shapes with great precision and uniform material thicknesses from a single piece of material. This means there is no welding or assembly to create the hollow feature, and fewer potential points of weakness or failure.
Excellent Surface Finish
The deep drawing process creates smooth surfaces because the press and dies form the metal with high precision. This means there are no jagged edges from cutting, no seams from joins, and no uneven spots from hammering. Components leave the press with a smooth surface that often does not require further finishing, aside from protective coatings or markings.
Reduction in Material Waste
Deep drawn metal forming minimizes waste because each blank is sized correctly to produce a hollow shape that is a consistent thickness. By starting with just the right volume of material, the finished piece will have no gaps or thin spots, and the precision tooling forms each blank the exact same way. As a result, there is little variation between pieces and from the specified dimensions and tolerances, and few pieces that need to be scrapped or reworked. This cuts down on waste and improves sustainability in manufacturing.
Deep Drawing Applications
ZERO Manufacturing serves multiple industries that use solid-construction cases, enclosures, and containers for protecting sensitive equipment, transporting materials and goods, and for storage. Some examples include, but are not limited to:
Logistics
Protective cases and enclosures are designed to contain tools, products, equipment, and other important items during transportation. Our products improve security and reduce the risk of damage or disorganization between the points of origin and destination.
Oil & Gas Industry
Our deep-drawn cans and enclosures provide protection for sensitive equipment and tools in the harshest conditions, like exposure to wind, rain, extreme temperatures, shock and vibration, and UV radiation. Rugged designs keep equipment enclosed and protected from damage in a variety of drilling and refining applications.
Automotive Industry
We offer large-scale production capabilities for high-precision automotive components like:
- Body panels
- Exhaust systems
- Fenders

Electronics
Deep drawing is useful in many electronics applications, including cases for transportation, transformer shells, EMI shields, and enclosures for monitoring equipment.
Aerospace Industry
Deep drawn items commonly used in aerospace applications are protective yet lightweight. Examples include electronic enclosures and junction boxes, flight line cases, and airline rotable containers.
Medical Industry
Medical cases, containers, and enclosures must be robust and easy to clean. Deep drawing is useful for products like heart monitor and instrument cases, sterilization trays, transport cases for medicine and equipment, and more.
Packaging and Consumer Goods Industry
In the consumer goods market, deep drawn goods include aerosol containers for cleaners, lighting fixtures, furniture components, and more. The packaging industry also uses deep drawn containers for beverages and food.
