Experts talk about the development and application of laser die-cutting technology (in Chinese)

Which suppliers exhibited laser die-cutting technology at this Drupa show?

Many companies exhibited laser die-cutting technology and equipment at this Drupa exhibition. Such as MORLOCK GMBH+Co. KG Corporation (mprint exhibited), CARGGS equipment company and AB Graphic company, etc. They mainly focus on the field of die cutting of trademarks and stickers. There are also similar laser die cutting systems, as shown by the IAser exhibited by AMPO print
System. Its application is wider and it can be used for lettering on taps and keys. Judging from the situation exhibited by many companies, the current laser die-cutting technology has become more mature

What is the working principle of laser die cutting?

The working principle of laser die cutting is similar to the principle of laser illumination. The rotation of the prism determines the point at which the laser falls. When die-cutting, the substrate should be stagnant. At this time, you can see a blue smoke coming out. Although this process is very short, the laser has already gone through the pre-designed path. The current laser speed has reached 1000m/s.

What are the characteristics of laser die-cutting compared to traditional die-cutting methods?

First, compared to the traditional die-cutting method, laser die-cutting eliminates die-cutting hardware and reduces the production cost of this part, which is the most direct.

Second, because it does not involve plate making, the production cycle is greatly shortened. If 2 hours are required, laser die cutting is feasible, while traditional die cutting methods are difficult to achieve.

In addition, the role of laser die cutting is further expanded, and it also has an anti-counterfeiting function. For example, an embossed effect is produced, or the thickness of the paper is burned in half. This is difficult to achieve with other processes.

Eliminating mechanical vibration is also a distinct feature of laser die cutting technology. In this way, die-cutting can be performed in the office and the working environment is improved. Although laser die cutting produces a certain amount of smoke, it can be solved by installing a protective cover, and the resulting smoke is not a toxic gas. Of course, laser die cutting also has the advantage of saving space and the like compared to conventional die cutting. (to be continued)
