Understanding How Metal Stamping Works
Metal stamping is where metal alloys are shaped and cut into various forms, more so be used as elements for structures and large machinery. Metal sheets can be designed in multiple per-determined forms to be used to make regular products such as cans and pans. The common primary alloys which are used for metal stamping are titanium, steel, aluminum, zinc, and nickel. Metal stamping is a productive and cost-effective method of producing several metal product kinds on a large scale.
In metal stamping, metal sheets are positioned in a press or die tool which has a special design cavity to give the desired shape from the metal sheet. The press slide and the upper part are connected, and the press bed is connected to the lower component. The punch which is a special component shoves the metal sheet to go through the die hence doing the authentic shaping operation. Now, when the stamp pressing process is being done, the purpose is to prevent corrosion, so the metal is plated using tin, gold, nickel, or palladium.
Plating adds to the solderable and wearability of the product. Other times the metal sheet is pre-plated prior to doing the stamping process. The product is then cleaned to get rid of metal stamping films and oils. It is then treated to heat to strengthen it because it is still in its soft state from stamping. To remove sharp corners from the product, it goes through the deburring process. Abrasives and chemicals do this process. Metal stamping comprises of more metalworking procedures like drawing, piercing, forming, and blanking in the machines. The press stamping has specific precision, force, and speed to achieve a set shape from the metal. Hydraulic and mechanical are the two metal stamping press types. They are available in a wide range of operating speeds, capacities, stroke lengths, and sizes.
Machining, fabricating, forging, die casting are metal processes that are quickly being replaced by metal stamping. The reason behind this is the involvement of low cost in metal stamping. Metal stamping also uses dies, which are cheaper compared to them that are used in casting and forging. In metal stamping the metals used are stronger compared to the ones that are used in the other metal process, which means that the end product also is stronger. The cost implication of the different processes such as plating and cleaning is also drastically reduced.
Furthermore, there are some products that can only be produced using metal stamping. These are friction plates, flywheel shrouds, engine bases, bushing seats, conveyor flights, brake flanges, balance cramps, brackets, and base weights. This does not mean that they cannot go through the other metal process only that this one is cost effective and fast. Metal stamping also comes in different kinds such as short run stamping, progressive die stamping, medical stamping, four slide stamping, electronic stamping and deep drawn stamping. The common type used is progressive die drawing where metal sheets are drawn using stamping and series dies simultaneously hence reducing time used.
