Let's take a look at the etching process of Yanming stainless steel

In the field of precision metal etching processing, the stainless steel etching process, due to its high precision and high flexibility, has become an important processing technology in high-end industries such as medical devices, electronic components, and aviation. As an expert in precision manufacturing of etched metals, Yanming Signage Technology Co., Ltd. has extensive experience in the field of stainless steel etching and provides customers with high-standard customized etching solutions. This article will provide a detailed introduction to the principle, process and core advantages of the stainless steel etching technology.

1、The principle of stainless steel etching process

Stainless steel etching is a processing method that removes specific areas on the material's surface through chemical corrosion to form precise patterns or structures. The core principle is to use corrosion-resistant films (such as photoresist) to protect the parts that do not need to be etched, and then selectively dissolve the exposed areas through acidic or alkaline etching solutions, ultimately obtaining high-precision metal parts.

2、The specific process of stainless steel etching

The process flow includes the following key steps:

Material preparation: Select high-quality stainless steel plates to ensure uniform material composition and no surface defects.

Photoresist coating: Evenly apply photosensitive resist on the metal surface and form the desired pattern through ultraviolet exposure and development.

Chemical etching: Immerse the sheet in the etching solution (such as FeCl₃ solution), precisely control the temperature and time, and dissolve the unprotected areas.

Cleaning and post-treatment: Remove residual resists, carry out polishing, passivation and other treatments to enhance the corrosion resistance and aesthetic appearance of the product.

3、The processing advantages of stainless steel etching technology

High precision and complex graphics: Capable of processing micron-level fine patterns, suitable for complex structures such as circuit boards and screens.

No mechanical stress: Avoid deformation caused by stamping or laser cutting, and maintain the original properties of the material.

Mass production: The same template can be reused, which is suitable for large-scale consistent processing and has a lower cost.

Environmentally friendly and controllable: Yanming adopts a closed-loop waste liquid treatment system, which complies with environmental protection standards.
