Metal Stamping and Metal Working
Sheet metal stamping dies are used to produce high precision metal components which are identical in shape and size. The dimensional accuracy and stability which you can achieve using precision metal stamping dies are very high and thus metal stamping dies are integral part of any manufacturing industry. You can see metal stamping components everywhere. From the electrical switches at your home to the computer you are surfing, from cars to air-crafts, everything need precision metal stamping parts. A highly specialized branch of mechanical engineering, metal stamping technology has grown considerably with the evolution of sophisticated machineries, CAD (computer aided design) and CAM (computer aided machining). This site is a resource for all those who are looking for detailed info about precision metal stampings and the manufacturing and trouble shooting of stamping dies.
Metal Stamping Firms
Sheet metal stamping firms could be of various types depending upon the type of work and accuracy of the metal stamped parts. Example fine blanking firms produce high precision stamping parts on thick sheet metals, but the production speed is relatively slow. Whereas a high speed press can produce thin sheet metal parts at a very high production rate.
Precision Metal Stamping Operations
Metal stamping dies can be used for various sheet metal operations like, shearing, blanking, piercing, bending, forming, coining, embossing, extrusion, deep drawing etc. Each of these operations are explained in detail on the corresponding pages.
Stamping Die Design
Die design is one field of precision metal stamping which gained considerable growth in the recent years. Computers have replaced drafters and drawing boards making the design easier, accurate, unambiguous and faster. Today various computer aided design (CAD) softwares like AutoCAD, Solid works, Unigraphics, Pro Engineer etc help stamping die designers life much easier. Designers also take the help of analysis softwares like Anysis and Nastran to predict the sheet material behavior during various metal stamping operations.
Stamping Die Manufacturing
Tool and Die making is one of highest precision engineering branches. It requires precision machineries and highly skilled work force. Tool and die makers and precision machinists are among the most highly skilled workers in manufacturing industry. Stamping die manufacturing involves step by step operations starting from design study, planning, pre-machining, heat treatment, final machining, bench fitting and assembly. Machining involves numerous operations from raw material cutting, drilling,
shaping, milling, turning, grinding, cylindrical grinding etc. to modern CNC machining operations like EDM, Wire EDM etc. We will discuss about precision machines and various cutting tools used on these machineries. The precision metal stamping die manufacturing involves a lot of bench work and assembly of different parts of dies after the final machining. A number of hand tools and precision measuring equipments are used throughout the process of metal stamping die making.
Stamping Die Maintenance and Troubleshooting
Precision metal stamping dies require regular maintenance to ensure the quality of the components it produces. Normally the maintenance work involves sharpening of cutting punches, replacing broken and damaged parts, working on dies to ensure the final stamped product meets all the quality specifications of customers etc. With the systematic processes like preventive maintenance consistent parts and enhanced life of stamping dies can be achieved.
