In adhesive label printing tasks such as OCA optical die-cutting, die-cutting machines occupy a crucial position. For label printing companies, die-cutting machines are as important as printing equipment, playing a pivotal role in product quality. Traditional die-cutting equipment can be broadly categorized into intermittent flatbed die-cutting machines, rotary die-cutting machines, and intermittent rotary die-cutting machines.
During this period, intermittent flatbed die-cutting machines were widely used. According to their structure, they were divided into two types: inclined back flatbed and horizontal flatbed. They had the characteristics of simple operation, low acquisition and operating costs, and almost all label printing companies had multiple such devices. However, with the intensification of competition, people's demands for efficiency and quality have become increasingly high. The disadvantages of flatbed die-cutting machines, such as slow speed and unstable pressure, have gradually become apparent. In addition, larger companies with more extensive plans have as many as ten or more such die-cutting machines, which also have major drawbacks such as large space occupation and high labor costs.
In recent years, the rotary die-cutting machine has gradually gained popularity in the industry due to its features such as simple pressure adjustment and high speed. In fact, the rotary die-cutting method has always existed, and many printers are equipped with inline die-cutting devices, allowing for the completion of printing and die-cutting in one operation. However, the high cost of die-cutting knives has limited its application to only long-run products, which is also an important reason why rotary die-cutting has not been widely adopted for a long time.
One of the most prominent characteristics of adhesive label work is its variety and small batch sizes, with many orders yielding a sales revenue that is not even enough to cover the cost of a single set of cutting dies. The combination of the low-cost feature of the flatbed die-cutting machine and the high-speed and high-efficiency advantage of the rotary die-cutting machine perfectly compensates for the deficiencies of both types of machines, making it the ideal choice for future upgrades in self-adhesive label production.
With the increasing recognition of die-cutting machine equipment, precision die-cutting technology is gradually gaining our acceptance, and its application scope is also gradually expanding and deepening. Applications such as LCDs, computers, and mobile phones are among the fields where die-cutting technology is widely used. Let's take a look at the application of die-cutting technology in these three fields.
Firstly, LCD products include LCD sealing gaskets, panel frame adhesive sheets, light guide plate reflective sheets, backlight plate reflective sheets, light-shielding sheets, optical film sheets, lamp tube reflective sheets, flexible circuit board adhesive sheets, bottom structure adhesive sheets, etc.
The advantages brought by the precision die-cutting technology of die-cutting machines in computer applications. Panel interlayer: no pollution, vibration damping, shock noise prevention, and anti-adhesion; LED surroundings: light leakage prevention, shock absorption, and improved air tightness; PCB bottom surroundings: shock absorption, vibration damping, gap filling, and thermal insulation; keyboard pads: resilience, no pollution, good dimensional stability; battery surroundings: no pollution, shock sound absorption, and improved air tightness; foot pads: good friction resistance, no pollution, good dimensional stability; disk drive tail pad: vibration damping, shock noise prevention, and improved air tightness; friction pads: good friction resistance, no pollution, good dimensional stability; disk cover cushion: vibration damping, motor noise blocking, dust prevention, and improved air tightness; speaker edge surround: noise prevention, gap filling; LCD surroundings: dust prevention, shock absorption, gap filling, and improved light shielding.
Precision die-cutting technology is applied in various aspects of mobile phones, including: window/lens maintenance, window/lens fixation, nameplates, serial number labels, earphone/microphone O-ring fixation, earphone/microphone dustproof mesh, window dustproof pad, LCD reflective film/backlight film, LCD structure fixation, battery compartment fixation, fixed keyboard, microphone dustproof mesh, microphone dustproof pad, wire fixation, battery panel cushion, earpiece/microphone cushion, earpiece/microphone dustproof pad, PCB fixation, and battery panel label.
