The Wear and Tear Mystery of Ultrasonic Garment Label Cutting Machines Unveiled

Are you fascinated by the precision and elegance of products cut by Ultrasonic Garment Label Cutting Machines? The flawless finish, devoid of any fading, cracking, blackening, or yellowing, elevates product quality and boosts profits. However, have you ever wondered why the cutting knife on these machines wears down relatively quickly?

To unravel this enigma, we must delve into the working principle of the Ultrasonic Garment Label Cutting Machine. This remarkable piece of equipment fuses ultrasonic welding technology with traditional cutting machinery. When the ultrasonic generator springs to life, it channels ultrasonic energy through a transducer to the welding head. This causes the welding head to vibrate intensely and rub against the cutter. The cutter is then carefully maneuvered towards the welding head through air pressure, resulting in a precise cut.

Primarily designed for ribbons and webbings, these machines employ straight knives, although the cutter’s shape can be altered to achieve bevel, trapezoid, parallelogram, dovetail, and more. The machine’s computer programming enables flexible parameter settings to cater to various industry needs.

Now, let’s uncover the root cause of cutter wear.

Firstly, the ultrasonic cutting process relies on high-speed friction and cutter pressure to achieve a clean cut. While a ribbon or webbing provides some cushioning, the cutter and the ultrasonic steel die don’t maintain complete contact. Nevertheless, with a staggering 200,000 vibrations per second, the cutter descends under air pressure and subsequently vibrates and rubs against the ultrasonic welding head. Despite the cushioning effect, especially for thinner ribbons, the friction persists, leading to cutter wear. Moreover, compressed air action exhibits a slight delay. Due to inertia, the cutter may not halt immediately during the pressing phase, potentially causing excessive contact with the ultrasonic welding head and further accelerating cutter wear. This is precisely why we emphasize maintaining optimal air pressure during the cutting process.

Secondly, the ultrasonic cutting process operates through high-speed friction and pressure exceeding 20KHZ, contributing to cutter wear. Ultrasonic vibrations, while essential for precision, also exert a grinding effect on the cutter. The ultrasonic welding head is crafted from high-quality alloy steel, heat-treated to achieve a remarkable hardness of 60 or more. Given the possibility of occasional collisions between the cutter and welding head, the ultrasonic cutter must also be constructed from top-notch mold steel.

Understanding the factors behind cutter wear equips you to maximize the lifespan and performance of your Ultrasonic Garment Label Cutting Machine. So, the next time you marvel at its craftsmanship, you’ll know why its cutter occasionally needs attention.
