One of the most difficult problems to overcome in any die protection application is protecting the components from the environment in which they must function. In a typical stamping application, oils, coolants, and other liquids and lubricants often are present that can wreak havoc on components.

Setting the processing variables is different between the net shape and non-net shape processes. While non-net shape variables have to be programmed constantly to change the tool's position in space to follow the unique shape of the part being made, the shape of the part for the draw forming net shape process is built into the die.

Compared with cold-formed parts, hot-stamped parts provide better formability at high temperatures and exhibit no springback on the final part.
High-speed laser cutting is a recent result of increased laser power and high acceleration motion technology, which have improved cutting speeds. Tilt beam 2D-3D systems allow laser cutting of small 3D parts, bevel cutting on 2D sheet metal and 3D parts, 3D trimming of small deep drawn parts, and processing of holes and cut-outs in hydroformed parts.

Adhesives offer several advantages that make them an attractive alternative to mechanical fastening or thermal joining, such as welding, soldering, and brazing. Advantages include the following: They can be effective on dissimilar metal substrates with dissimilar melting points; they do not cause distortion, discoloration, or weld worms; holes do not need to be drilled into the material in preparation for fasteners; and they distribute stress load evenly over a broad area.

Both laser and waterjet cutting systems produce precision parts, and in many applications, either is appropriate. This article, which discusses the benefits and limitations of both technologies, can help you decide which is best-suited for your operation. In some cases, utilizing both can increase manufacturing flexibility and your business capabilities.

Cutting shear, or the angle ground into the end of a punch, has a big effect on punch deflection and breakage, as well as press tonnage required. Retainers, which hold the punch to the die shoe, also are important. The backing plates, ball lock punch retainers, and headed styles of punches and retainers all require careful consideration.
