Deep drawing is a Sheet Metal Fabrication process in which a sheet metal blank is radially drawn into a forming die by the mechanical action of a punch. It is thus a shape transformation process with material retention. The process is considered "deep" drawing when the depth of the drawn part exceeds its diameter. This is achieved by redrawing the part through a series of dies. The flange region (sheet metal in the die shoulder area) experiences a radial drawing stress and a tangential compressive stress due to the material retention property. These compressive stressesesult in flange wrinkles (wrinkles of the first order). Wrinkles can be prevented by using a blank holder, the function of which is to facilitate controlled material flow into the die radius.
Deep drawing is one of the most widely used processes in sheet metal forming. It is used in a wide range of production processes. For example, it is used by the automotive industry to manufacture car parts; it is also used for making household items such as stainless steel kitchen sinks.

Laser cutting machine is divided into two kinds because of follower's current technological development, common hand-held and laser equipment, this article mainly explains the future development direction of laser cutting machine, because laser technology has a high speed, high efficiency, high brightness The characteristics, so in the future development direction of laser technology is a feature, high power!
Why this is so, because the current laser cutting machine equipment is equipped with 10,000 watts of power equipment, following the improvement of the quality of the laser beam in terms of processing effects, the processing effect has been increased to a certain extent, if the quality of light declines, then It will make the growth of laser cutting machine equipment unsatisfactory. Therefore, in order to improve the quality of light, the high brightness of the laser is promoted. Therefore, in the future development direction, the price of laser cutting machine will be affected by this factor.
Secondly, the influencing factors are the continuous improvement of the follower laser cutting machine, the more intelligent laser equipment, and the flexible use of processing. Therefore, in the future, the development of a wide frequency band will be the development of the so-called wide frequency band is the laser. Will become adjustable, casual work, currently using a short-frequency working principle, the future is likely to use long-wave, or even millimeter wave, and the appearance of ultraviolet frequency, but also accelerate the development of today's laser frequency, in This will be the focus on the overall laser cutting machine price.
