How to choose the punching machine through the specification ?

Through the specification selection, the following principles should be followed while choosing the punching machine's specification: 

1, The nominal pressure of the press punching machine must be greater than the stamping process force. However, when it comes to the long working process of the procedure, it should not only meet the size of the craft force, but also consider to meet its workload curve . 

2, The press slider stroke should be able to meet the workpiece height in the required size, and should be removed from the mold successfully after the stamping process . 

3, Productivity requirements should be calculated according to its free frequency. 

4. The closure height, table size, slider size, mold handle hole size must be able to meet the correct installation requirements of the molds. For crank pressure machine, the closing height of the mold should  be between the maximum mold height and the minimum mold height. The size of workbench should generally be greater than the mold base 50-70mm (unilateral). In order to install, plate aperture should be larger than the workpiece or waste projection size, so that the size of the mold handle should be leeched to match the size of the mold handle hole.

Fiber Laser Cutting Machine

Nowadays laser cutting machine is more and more widely used, as it is with high speed, high precision and automation. It can save manpower and improve production efficiency.  The laser is shot from laser generator, through optical system, focus to high power and density laser beam. The beam shoots on surface of workpiece and makes it reach melting point or boiling point, at the same time, the high pressure gas which is on the same axis with laser beam blow the melting or pneumatolytic metal away. That is the basic reason of laser cutting. According to the laser generator, there are two types – CO2 type & fiber type. The frequency of the CO2 laser requires higher wattage of lasers to penetrate through metals. CO2 laser systems are best suited to cutting wood, acrylic, plastic, and fabric.  Fiber laser cutting machine  is much more energy saving. In the situation that reaches same performance, whole fiber cutting can save around 70% energy than CO2 type. The wattage can...
