1）Stamping production efficiency is high. The progressive die can complete the process of blanking, flanging, bending, drawing, stereo forming and assembling of complex parts, reduce the work of intermediate transporting and repetitive positioning, and the increase of work number does not affect the production efficiency, so it can punch very small.

2) The operation is safe and simple. When progressive die is stamped, the operator does not need to put his hand into the dangerous area of the die. For mass production, automatic feeding mechanism is also adopted, and safety detection device is installed in the die.

3) High quality of products. The progressive die completes the whole forming process of the product in one die, which overcomes the operation invariability and accumulated error caused by multiple positioning with simple die.
