In the printing of self-adhesive labels such as OCA optical die-cutting, die-cutting machines play a very important role. For label printing companies, die-cutting machines and printing equipment are equally important and play a crucial role in the quality of products. The traditional die-cutting equipment is roughly divided into several types: intermittent flat die-cutting machine, rotary round die-cutting machine, intermittent round die-cutting machine, etc.
During this period, the intermittent flat die-cutting machine is widely used. According to its structure, it can be divided into two types: inclined back flat die-cutting machine and line flat die-cutting machine. It has the characteristics of simple operation, acquisition cost and lower application cost. Almost all label printing companies have multiple such equipment. However, with the intensification of the competition, people's demand for power and quality is becoming higher and higher. The defects such as the slow speed and unstable pressure of the flat-pressing die-cutting machine are gradually emerging. In addition, there are more than ten such die-cutting machines in companies with larger plans, which also take up large space and high labor costs.
In recent years, because of the characteristics of simple pressure adjustment and fast speed, the circular die-cutting machine has gradually attracted the industry's attention. In practice, the method of circular die-cutting has always existed. Many printers have connected die-cutting equipment. Printing and die-cutting are finished at one time, but the cost of die-cutting knife is too high and only suitable for long-line products. This is also an important reason why circular die-cutting can not be developed for a long time.
As one of the most obvious characteristics of adhesive label work is a variety of small batches, the sales volume of many orders is not equal to the quotation of a set of knives. In order to meet the market demand, Beijing Oulu Xinda Printing Machinery Co., Ltd. has launched a high-speed flat-pressing die-cutting machine, which continuously feeds paper with a die-cutting speed of 80m/min. The flat press die-cutting machine has the advantages of low cost and high speed and efficiency, which perfectly compensates the shortcomings of the two models, and is the choice for future upgrading of self-adhesive label work.
With the improvement of the recognition of die-cutting machine equipment from time to time, precision die-cutting processing technology has gradually been recognized by us, and the scope of application is also gradually expanding and deepening. For example, LCD, computer and mobile phone are the areas where die-cutting machine processing technology is widely used. Let's take a look at the application of die-cutting technology in these three areas.
First of all, LCD products, including LCD sealing gasket, panel rack rejection adhesive sheet, light guide plate reflector, backlight plate reflector, light shield, optical film sheet, lamp tube reflector, flexible circuit board adhesive sheet, bottom structure adhesive sheet, etc.
Die-cutting machine precision die-cutting processing technology in the field of computer applications. Panel interlayer: non-pollution, loosening, anti-impact noise, anti-adhesion; LED surrounding: anti-light leakage, shock absorption, and improved air tightness; Around the lower part of PCB: absorb shock, shock, fill gaps, and heat insulation; Keyboard gasket: anti-elastic, non-polluting, good dimensional stability; All around the battery: no pollution, absorbing impact sound, improving air tightness; Foot pad: good resistance, no pollution, good scale stability; Rear pad of disk drive: absorb shock, prevent impact noise and improve air tightness; Conflicting gasket: good resistance, non-pollution, and good dimensional stability; Disk cover cushion: absorb shock, block motor noise, prevent dust and improve air tightness; Horn edge: prevent noise and fill gaps; LCD surrounding: dust prevention, impact absorption, gap filling, and improvement of shading.
