Laser etching technology: breaking through conventional processing difficulties and innovating a new chapter in the manufacturing of heating elements

With the rapid development of modern industrial technology, heating sheets, as an indispensable core component of many electronic devices, have increasingly higher requirements for processing accuracy and efficiency. However, in the conventional processing process, heating sheets often face a series of technical difficulties, such as low processing accuracy, large material loss, and low production efficiency. This article will explore how to solve these problems through laser etching technology and bring innovation to the heating sheet manufacturing industry.

1. The main problems faced by heating sheets in conventional processing

In conventional processing, the manufacturing process of heating sheets usually adopts traditional processes such as mechanical cutting and chemical etching. However, these methods have exposed many problems in practical applications. First, the mechanical cutting processing accuracy is low and it is difficult to meet the high-precision requirements; secondly, waste and pollutants are easily generated during the chemical etching process, which has adverse effects on the environment; finally, the production efficiency of traditional processes is low and it is difficult to meet the needs of large-scale production.

2.Principles and advantages of laser etching of heating sheet

Laser etching process is a technology that uses high-energy laser beams to accurately cut and etch materials. The principle is to use the high energy density and high focus of the laser beam to make the material reach the melting point or vaporization point in an instant, thereby achieving precise cutting and etching. Compared with traditional processes, laser etching has the following significant advantages:

鈻燞igh precision: Laser etching can achieve micron-level or even nano-level processing accuracy, meeting the needs of high-precision processing of heating sheets.

鈻燙ontactless processing: During the laser etching process, the laser beam has no direct contact with the material surface, avoiding damage and deformation that may occur during mechanical cutting.

鈻燛nvironmental protection and energy saving: No chemical reagents are required during the laser etching process, which reduces the generation of waste and pollutants and conforms to the green and environmentally friendly production concept. At the same time, the energy utilization rate of the laser beam is high, which reduces energy consumption.

鈻燞igh efficiency: Laser etching has the characteristics of rapid processing, which can greatly improve production efficiency and meet the needs of large-scale production.

Three, Application of laser etching technology for heating sheetsIn the manufacture of heating sheets

The application of laser etching technology in the manufacture of heating sheets is mainly reflected in the following aspects:

鈻燩recise cutting: The laser etching process is used to accurately cut the heating sheet to ensure the accuracy and consistency of the product size.

鈻燙omplex pattern etching: Laser etching can achieve precise etching of complex patterns to meet the needs of personalized design of heating sheets.

鈻燤icro hole processing: Micro holes can be processed on the heating plate through laser etching process to improve the heat dissipation performance and reliability of the product.

鈻燬urface treatment: Laser etching can also perform special treatment on the surface of the heating plate, such as removing the oxide layer, improving the surface roughness, etc., to improve the performance and appearance quality of the product.

In short, The heating sheet laser etching process has brought innovation to the heating sheet manufacturing industry with its advantages of high precision, non-contact processing, environmental protection and energy saving, and high efficiency. With the continuous advancement of technology and the continuous expansion of application fields, it is believed that laser etching technology will play a more important role in the future.
