Metal stamping, also known as pressing is the process of placing a piece of flat sheet metal into a stamping dress where a tool and die surface makes the metal into a net shape. Stamping includes a variety of processes including punching, blanking, embossing, bending, flanging, and coining. Most often stamped components are made from cold sheet metal but other materials such as polystyrene can be used as well. Brukar Inc. has great manufacturing partners with excellent stamping facilities to meet you’re your drawings requirements.

Deep drawing is a metal forming process that involve a bank piece of sheet metal which is formed using a forming die. The piece of sheet metal is formed into a component with a hallow body. To be considered a deep drawn part the depth of the drawn part must exceed its diameter. Stainless steel, mild steel and other steel grades are used in this cold metal process. Deep drawn components are a great alternative to casted or welded components. Brukar Inc., has excellent deep drawn metal forming facilities.

Metal Spinning, also known as spin forming, spinning or metal turning is a metal forming process that uses a disc or tube of metal that is rotated at high speed and formed into an axially symmetric part. This process uses cold work metal. Spinning is performed by hand or by a CNC lathe machine. A great advantage to metal spinning is that forming parameters and part geometry can be altered quickly, and at a lesser cost than other metal forming processes. This process can be used for both larger and small production quantities.

There are various tube bending processes available to you today. It is important to pay attention to required bending data and apply that understanding to what is commercially available to meet you needs.

Required physical information about the finished part to achieve a successful component that fits your equipment needs are:

a: Outside diameter (OD)

b: Wall thickness

c: Bending radius (usually measured from tube center line)

d: Material

e: Part configuration

f: Bend quality required (ovality and wall thinning)

Of interest in the selection of a bending method are items a, b, and c. These factors

correlate to each other and will directly influence the supplier selection to meet your needs.

Bending data can be defined as:

a: Degree of bend sometimes called “angle”

b: Distance between bends sometimes called “length”, “feed”, or “position”

c: Plane of bend, sometimes called “twist”, “rotation”, or “orientation”

BENDING METHODS

1. Manual bending
2. Semi-automatic bending
3. CNC bending
