A unique selling point of the draw die is the pressure pad, which comes with a sensor to locate and hold down metal blanks on the die shoe. An advanced knock out rod, also known as an ejector pin, push finished work pieces out of the die, preventing improper installation.More
Frame rails are critical parts to a car, and does the heavy lifting of the vehicle. Frame rails need to be rigid and accurate to fit seamlessly with other parts of the car. Stamping die for frame rails includes a great rigidity, accuracy, thermal stability and toughness.More
Stamping dies are a special precision tool that is designed to cut and form sheet metal into a desired shape or profile design. Die cutting and forming sections are typically made from special varieties of steel that can harden, typically called tool steel. The dies can also contain cutting and forming sections made from hard, wear resistant materials, such as carbide.
Stamping is a cold-forming operation. This means that the die or sheet material is exposed to heat intentionally. However, stamped parts generally exit the dies incredibly hot, due to the friction generated during the cutting and forming processes.
Dies come in a variety of sizes, depending on the end use. Dies produced for use in microelectronics can fit in the palm of a person's hand, and those used for automobile body panels can be up to 20 feet square and 10 feet thick.
The final part is called a piece part, and some dies are capable of making more than 1 piece part per cycle, and cycles can be as fast as 1,500 cycles (also known as strokes) per minute.
Though there are a variety of stamping dies, all are designed to perform two basic functions: cutting, forming, or both. Line dies are dies that are either manually or automatically loaded dies, and progressive and transfer dies are fully automated.
