DEEP DRAWING
DEEP DRAWING
Deep Drawing is the term we use for the process of giving a piece of sheet metal a three dimensional depth. A flat piece of metal can be deep drawn into a shape that resembles a cup or bowl. We are able to design your part if you only have an idea of a prototype, or bring in your sketched out plans and we will make it happen.
Drawing is very similar to bending and forming in the way that a press/ punch can be used to shape sheet metal. Drawing can be used to punch a hollow cup or cube like shape into sheet metal. The term deep drawing is used to describe a process where the depth of the draw or punch is deeper than the diameter of the drawn metal part. If you are in need of deep drawing or any other metal manufacturing process to design or develop your metal part, the ABT Metals team is here to help. Our engineering team will work with you to create an efficient process that will ensure that you have the metal parts you require in a timely and efficient manner. Whether you have drawings of your part ready to go, or need us to help you design your metal part from the ground up, we look forward to serving you.
Metal drawing is a metalworking method that involves stretching and forming metal with tensile force. The procedure is generally carried out cold to guarantee precise tolerances, enhanced grain structure and surface polish, and improved material characteristics.

HOW IS METAL DRAWING DONE?
The process of shaping metal into a part or component is known as metalworking. Metal drawing, which involves moving a metal through a mold or die, is one of the most frequent metalworking methods. Extrusion is a comparable operation in which metal is pushed through a die using a drawing punch.
Metal drawing can produce a metal with a depth that is equal to or greater than the width or radius of the metal. This type of metal drawing, also known as deep drawing, can generate high-strength, low-weight goods while saving a lot of money, making it an attractive alternative for many manufacturers.
HOT VS. COLD METAL DRAWING?
Cold Metal Drawing
A piece of metal is formed at room temperature during cold metal drawing. It can be heated to a few degrees, but generally, the metal can only be heated to a moderate temperature. There are two methods of doing this: Stamping and Hydroforming.
Hot Metal Drawing
A hot Drawing press resembles an oven in that it surrounds a die that is placed inside a box. To hit on the die, the oven must be heated to 2000 degrees, which can take up to an hour. The material is then squeezed between the male and female die parts. The portion is cooled after the initial push. Hot drawing can create two pieces per hour, making it perfect for tiny, specific orders made of materials that cannot be cold formed. Grade 5 6Al-4V titanium, for example, cannot be cold-formed. Hence hot drawing is an option.
METAL DRAWING PROCESS
Metal drawing is usually done cold, meaning the metal to be shaped kept at room temperature rather than being heated. A cold metal drawing method assures that the tolerances of the drawn product are more accurate, that the grain structure, that the surface finishes are better, and that the product’s qualities are improved overall.
The blank is placed into the die during metal drawing and mechanically grasped to pull it through. The workpiece will take on the shape of a hollow box or cylindrical vessel as it passes through the die. Depending on the form of the die, the sides might be straight, tapered, curved, or a mix of all three. The workpiece can then be pulled through the second set of dies to decrease the diameter and length of the workpiece while keeping the thickness of the walls relatively unchanged.
WHAT IS DEEP DRAWING METAL?
Deep drawing is a sheet metal shaping technique that uses the mechanical action of a punch. A flexible rubber diaphragm is used to manufacture a flat sheet metal blank over a single, rigid shape-defining tool under uniform hydrostatic pressure.
