Metal stamping is the process of cutting and shaping metal alloys into specific forms, especially to be used as components for large machinery or structures. Metal sheets can be molded into different pre-determined shapes for use as regular products like pans and cans. The most common alloys that are used in metal stamping are steel, zinc, nickel, aluminum and titanium. Metal stamping is a very cost-effective and productive way of producing many kinds of metal products on a large scale.

In metal stamping, the metal sheets are placed in a die or a press tool that has a specially designed cavity that gives the preferred shape to the metal sheet. The upper part of the die connects to the press slide while the lower component connects to the press bed. A specific component known as the punch pushes the metal sheet through the die, thus performing the actual shaping operation. After pressing, the metal is plated with gold, palladium, nickel or tin to prevent corrosion.

Plating also increases the wearability and solderable nature of the product. Sometimes, the sheet is also pre-plated before the stamping process, and then the product is cleaned to remove excess metal stamping oils and films. The product is then heat treated to make it stronger since it is still in the soft state after stamping. The product is then subjected to the deburring process for removing the sharp corners. This is done by using chemicals or abrasives. Metal stamping also involves other metalworking processes like piercing, blanking, forming and drawing on the same machines.

Stamping presses have specific force, speed and precision for giving a specific shape to the metal. There are two types of metal stamping presses: Mechanical and hydraulic. These are available in an extensive range of capacities, sizes, stroke lengths and operating speeds.

Metal stamping is slowly replacing other metal forming processes like die casting, forging, fabricating and machining. One reason for this is the very low costs involved in metal stamping. The dies used for metal stamping cost less than those used in forging and casting. Also, the metals used in metal stamping can be harder than those used in other processes, thus making the end product stronger. The cost of the secondary processes, like cleaning and plating are also considerably reduced.

Moreover, there are certain products that have to be produced only through metal stamping: Base weights, brackets, balance clamps, brake flanges, conveyer flights, bushing seats, engine bases, flywheel shrouds and friction plates. There are also different kinds of metal stamping including: Deep drawn stamping, electronic stamping, Fourslide stamping, medical stamping, progressive die stamping and short run stamping. The most commonly used type is the progressive die drawing wherein a metal sheet is drawn through a series of dies and stamping is done by all the dies simultaneously, thus considerably reducing the time it takes.

An Introduction to Metal Stamping Machines
Metal stamping machines are used to give the exact shape and parameters to the metal products. When a metal sheet is inserted into the metal stamping machine, it can be molded into the exact shape.

Precision Machining
Precision machining involves producing of metal parts, which are extremely intricate and are mainly made from thin metal sheets. Besides precision metal parts are often custom made for specific purposes. However there are distinct techniques such as chemical etching, metal stamping, and RF shielding for producing precision metal parts.

Precision Metal Stamping
Precision metal stamping sounds like a difficult process to describe. The main goal of this article is to simplify the intricate details of this process.

The Important Function of Metal Stamping Dies
Metal stamping dies are the devices used in metal stamping machines. Each metal stamping machine can have one or more than one dies depending on the kind of machine. Dies are the main components in metal stamping machines that do the actual casting, punching, cutting and shaping of the metal sheet.

Metal Fabrication Processes - What is CNC Punching?
There are several ways to create holes in steel. One method is called milling, which involves drilling. Another method is called stamping, involving a punch press. Still another method utilizes a process called CNC Punching, which involves computer aided positioning systems to quickly and efficiently create metal parts. While other methods such as laser and waterjet cutting are valuable for other reasons, this informative article addresses CNC Punching in depth.

Metal Stamping Company Buys New Presses
Component Engineers Inc. is proud to add three new power presses to the plant, taking the total in the facility to 38. One of the presses added is a Minster, 75-ton straight side, which is the third of its kind at the CEI facility. The other two presses are Minster 32-tons, also straight sided.

The Custom Metal Stamping Process
Today, manufacturing has embraced a wide range of advanced technologies that have enabled the reduction of turnaround time considerably. As a result, demand on the metal stamping industry has also increased as the components have to be made to be exactly suitable to the final product.

What is Metal Stamping?
Metal stamping is the process of cutting and shaping metal alloys into specific forms, especially to be used as components for large machinery or structures. Metal sheets can be molded into different pre-determined shapes for use as regular products like pans and cans.

A Look at Sheet Metal Stamping
Sheet metal stamping is the system wherein metal sheets are used for producing final products. When a metal sheet is inserted into the die or the press, it is molded into the required shape and size. Metal sheets of only a certain thickness can be inserted into metal stamping machines.

The Process of Precision Metal Stamping
Precision metal stamping is the process of making 3-dimensional metal parts, lettering and other embossing. This is a kind of metal stamping used mostly for decorative purposes. It is similar to normal metal stamping, which is the process of molding metal into different shapes and sizes.

Valuable tips to buy original and stamped Sheet Metal
Some times, sheet metals are used to produce different components by using the process of sheet metal stamping. In the process of sheet metal stamping to produce stamped sheet metal components, a metal sheet is inserted into a die or a press. By applying pressure on the die, the sheet metal is moulded into the required shape and size Sheet metals up to only a certain thickness could be used in these metal stamping machines. For most of the metals, the maximum thickness is ¼ inch. But, in special cases, machines could be designed to handle thicker sheet metal. Also, only sheets made from specific materials could be used. They include aluminum, brass, steel (both hot rolled or cold rolled), galvanized steel, stainless steel, copper, zinc and ...
