The Process of Precision Metal Stamping
By Josh Riverside
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. The products obtained through metal stamping are used as components for some larger products in other industries. The most common metals and alloys used for precision metal stamping are copper, aluminum, brass, beryllium, nickel, nickel silver, steel, stainless steel, phos bronze and titanium.
Precision metal stamping is applicable to many industries like computers, electronics, electrical, dental, aerospace, instrumentation, military specs, defense, telecom and automotives. There are many methods in precision metal stamping for producing stamped prototypes. Blank creation is one such method. Blank creation involves the creation of a flat state of the component. The flat blank sheet is then used to make the part's features. In blank creation, there are many processes like nibbling, chemical etching, water jet cutting, wire EDM, punch and die.
There are also many methods for producing prototypes by precision stamping. The type of method used depends on the size and intricacy of the parts to be produced as well as the number of prototypes. Single part transfer is one such method in which single parts are transferred from one station to the next for blanking and metal forming. The main advantage with this method is the cost effectiveness. One single, standard system can be maintained for designing, manufacturing and holding tooling inserts. However, this system is slow because it needs individual prototype parts. The other method is the progressive strip prototyping which involves the automatic transfer of the metal from one stage to the next.
Precision metal stamping can be done at very high speeds and even up to 1,200 strokes per minute. Precision metal stamping gives several advantages like the ability to use any metal or alloy and creation of components with very precise dimensions and shapes. Plating can also be very precise which is helpful when working with precious metals like gold and palladium.
