About Metal Stamping

Posted by Heiwhite on February 23rd, 2020

Metal stamping is considered to be a procedure involving cutting and shaping of metal alloys, converting it to specific forms. It is created for large structures or machinery as components. With Precision Metal Stamping Part, it is possible to mould metal sheets into wide range of pre-determined shapes. This way, it can be used for variety of products like cans and pans. Titanium, aluminium nickel, zinc and steel are few of the common alloys. It is also stated to be a productive and cost effective to produce several types of metal products in large quantities.

Metal sheets in metal stamping are placed in press or die tool having special designed captivity to provide it with the preferred shape. The die’s upper portion connects to press slide and lower component tends to connect to press bed. The specific component is termed as punch, which pushes metal sheet across the die, thereby carrying out actual shaping operation. Once metal gets pressed, it is plated using palladium, gold, tin or nickel to prevent corrosion.

Need for plating

With plating, it is possible to improve the product’s solderable nature and wearability. The sheet at times gets pre-plated prior to stamping process. Then, product gets cleaned, so as to eliminate excess of metal stamping films and oils. Later, it gets heat treated to enhance its strength as it is found to be in soft state once stamped. Deburring process is then performed to eliminate sharp corners, which is usually performed with the using of abrasives and chemicals. There is involved various metalworking procedures in metal stamping like drawing, forming, blanking and piercing on same machines.

Types

Stamping presses do come with specific speed, force and precision to provide the metal with a specific shape. Metal stamping presses are of two types, namely, hydraulic and mechanical. They can be found in varying sizes, capacities, operating speeds and stroke lengths.

Other metal forming procedures are found to replace slowly metal stamping like forging, die casting, machining and fabricating. One major reason cited for the same is low cost of metal stamping. Dies that is used for this process is inexpensive when compared to casting and forging. Moreover, metals used for metal stamping is much harder when compared to the ones that are used for other procedures. Thus, the end product is made much stronger. Costs involved in secondary procedure like plating and cleaning is reduced considerably.

Besides this, there are present certain products which are produced only through metal stamping. These are balance clamps, brackets, base weights, brake flanges, bushing seats, conveyor flights, engine bases, friction plates and flywheel shrouds. Also exist varying metal stamping types like electronic stamping, deep drawn stamping, fourslide stamping, short run stamping, progressive die stamping and medical stamping. The commonly used one is however progressive die drawing. In this case there is drawn a metal sheet using series of dies. Stamping is carried out simultaneously by all dies, thereby reducing time taken significantly.
