Metal stamping is otherwise known as pressing in that a flat sheet of metal on a stamping press that can bend, press, fold or stretch the metal. The process can either be a single or multiple stage process. Companies that use metal stamping find it to be a fast and economical method of producing large quantities. Metal stamping as being economical means that there is a high production flow thus the cost per piece is low. Needing a one-off product makes its hard for metal stamping to be done. If metal stamping is to be done on this product then the cost would be prohibitive. Carrying metal stamping for a one-off product also results to additional tooling costs and longer preparation times.
Metal stamping contract manufacturing includes a variety of manufacturing processes such as punching, embossing, bending, flanging and coining. Punching is considered to be the process of using a press punch to force a tool through the work piece in order to create a hole through shearing. Sheet metal, paper, vulcanized fiber and some forms of plastic sheet are the types of materials in which punching is applicable. Punching is considered to be the cheapest method of creating holes aside from being applied in other materials.
The production levels of carrying out punching is between medium to high levels. The major components of a press that is mechanically driven include; motor, frame, ram, die posts, bolster and bed. In order to carry out punching then a machine press is used.
The operations of metal stamping are many and they include; flinging, coining, drawing, stretching, ironing, curling, hemming, necking among others. When the material is deformed or bent along the straight line its referred to as bending while flinging is when the material is bent along a curved line. When materials are compressed into a pattern then its referred to as coining. All in all the process of metal stamping is very complex.
Machines and structures from Meco are built using raw materials that better your manufacturing needs. The metal fabrication process shapes the metal into different parts by also removing materials. Ways in which the materials are removed include; hole creation and cutouts, material changing through bending and stretching the metal. Metal fabrication has several advantages such as; rapid prototyping, a variety of fabrication procedures and use of recent technology, equipment, press brakes and assembly processes. Fabrication of metals use the latest technology and good examples of these include; shear and laser cutting.
Labor intensiveness and longer production periods are some of the disadvantages of metal fabrication. In comparison to metal stamping, the costs of metal fabrication is very high. The process of fabrication is usually not possible when complex parts and components are used for stamping.
