There are many brands of pneumatic marking machine on the market, similar in appearance, but the price span from 2000 to 10000 yuan. So is there a simple and easy to implement standards to test the performance of a pneumatic marking machine good or bad? The answer is to use the printing speed and accuracy testing, the method is as follows:

Engraving 26 uppercase English letters, font size set by the operator (the smaller the word the shorter the engraving time, but the higher the precision requirements of the machine), in the same material (such as stainless steel plate) on the engraving with different speeds, not counting the time of the workpiece to take and put, counting only the net time of engraving, with no more than 8 seconds to engraving, although fuzzy, but recognize all the letters, the marking machine with a better all-round performance. Engraving with 10 seconds, there are individual letters are not recognized, the marking machine performance is poor. If you use 12 to 13 seconds to print, all the letters should be very clear and more beautiful.
