Detailed Description for Electrical stamping

 

              Electrical Stamping for ceiling fans, table fans, exhaust fans, air circulator motors, submersible pumps, transformers, chokes, low wattloss ballasts, generators, large motors - alternators, tacho generator lamination, magneto lamination for self starters of automobile industry, etc. The Electrical Stamping is made in CRNGO, CRGO and Low Carbon CR Steel suitable for electrical applications.

              Electrical Stamping is the process of placing flat sheet metal in either blank or coil form into a stamping press where a tool and die surface forms the metal into a net shape. Stamping includes a variety of sheet-metal forming manufacturing processes, such as punching using a machine press or stamping press, blanking, embossing, bending, flanging, and coining. This could be a single stage operation where every stroke of the press produces the desired form on the sheet metal part, or could occur through a series of stages.

Dia            : 50 mm to 210 mm

 

 

Operations:

Bending - the material is deformed or bent along a straight line.

Flanging - the material is bent along a curved line.

Embossing - the material is stretched into a shallow depression. Used primarily for adding decorative patterns. See also Repoussé and chasing.

Blanking - a piece is cut out of a sheet of the material, usually to make a blank for further processing.

Coining - a pattern is compressed or squeezed into the material. Traditionally used to make coins.

Drawing - the surface area of a blank is stretched into an alternate shape via controlled material flow. See also deep drawing.

Stretching - the surface area of a blank is increased by tension, with no inward movement of the blank edge. Often used to make smooth auto body parts.

Ironing - the material is squeezed and reduced in thickness along a vertical wall. Used for beverage cans and ammunition cartridge cases.

Reducing/Necking - used to gradually reduce the diameter of the open end of a vessel or tube.

Curling - deforming material into a tubular profile. Door hinges are a common example.

Hemming - folding an edge over onto itself to add thickness. The edges of automobile doors are usually hemmed.

Piercing and cutting can also be performed in stamping presses. Progressive stamping is a combination of the above methods done with a set of dies in a row through which a strip of the material passes one step at a time.
