As a new light source invented in the last century, laser has the characteristics of good directivity, high brightness, good monochromaticity and high energy density. It has been widely used in industrial production, communications, information processing, medical and health, military, cultural education and scientific research, etc. According to statistics, from high-end optical fiber to common barcode scanners, the market value of laser-related products and services is up to trillions of dollars each year. Chinese laser products are mainly used in industrial processing, occupying more than 40% of the market space.
The advantage of laser processing on the upper is that various patterns can be quickly carved and hollowed out on the surface of various upper materials. Since laser processing is a non-contact processing method, it will not cause any external deformation of the upper. It has many advantages such as high engraving accuracy, hollow-out without burr edge, and can process any shape.
However, it is also because of the high-density energy characteristics of lasers that when laser cutting or laser cutting upper materials, especially light-colored materials (such as white beige), or special materials (such as mirror materials, etc.), the upper On the surface or inside, it is easy to burn or yellow.
In order to prevent this phenomenon, during the production and processing, it is necessary to perform certain protection treatment on the surface of the shoe upper. The usual methods are:
1. Stick the protective film, it must be flat, tight, no bubbles.
2. Wet some shoe uppers. This method is applicable to some materials.
3. Adjust the laser processing parameters and adopt the method of multiple times and small firepower.
These three points are used to prevent the high temperature generated during laser cutting or laser hollowing the upper, which may cause burns on the surface or inside of the upper.
Sino-Galvo Tech. was founded in 2001, our galvo scanner products are widely applied in laser marking, medical beauty, 3D printing, laser cleaning, laser welding, precision cutting, scientific research, and military fields, etc. Any more information needed or if you have any special requirements, pls. contact us for further communication.
