< p > laser processing is to use the high energy density characteristics of the laser to irradiate the surface of the product and vaporize the surface material of the product or produce a chemical reaction process of color change.

< /p >

< p > because the laser processing technology has the characteristics of high automation, high precision, high processing efficiency and simple operation. It adapts to the development trend of the international a href= "//www.sjfzxm.com/" target= "_blank" > shoes < /a > production technology trend. Therefore, the technology and equipment of excitation processing are being popularized and popularized in the footwear industry at an alarming rate.

< /p >

< p > laser processing has the advantage of rapidly carving and hollowing out all kinds of patterns on the surface of all kinds of shoe upper materials. Since laser processing is a non-contact processing method, it will not produce any outward deformation of the shoe upper.

It has many advantages, such as high engraving accuracy, hollowing without burrs, and processing arbitrary shape.

< /p >

< p > however, because of the high density and energy characteristics of laser, laser cutting or laser cutting of shoe upper material, especially light colored materials such as white beige, or special materials, such as mirror material, can cause chill or yellowing on the surface or inside.

< /p >

< p > to prevent the occurrence of this phenomenon, it is necessary to protect the vamp surface in production and processing. The usual methods are: < /p >

< p > 1. Paste the protective film. It must be pasted tightly and tightly, and there must be no bubbles.

< /p >

< p > two, wetting some vamp, this method is suitable for some materials.

< /p >

< p > three, adjusting laser processing parameters, using multiple times of small firepower.

< /p >

< p > the principles of the above methods are to prevent the laser processing from cutting through or the high temperature generated by laser hollowing up vamp, and the necessary protective measures to burn the surface or inside of the shoe upper.
