Description

Technical Field

[0002] Metal craft processing is a field involving a variety of processes and technologies, aiming to create metal products with artistic value and practical functions. Metal craft etching is a technology that uses chemical reactions or physical impact to remove part of the material, thereby forming concave and convex or hollow patterns on the metal surface. Metal etching technology can be divided into wet etching and dry etching. Wet etching is a chemical reaction between chemical solutions and the metal surface to remove part of the material.

[0003] The metal etching process typically includes the following steps: Pre-treatment: This includes degreasing, washing, etching, rinsing, and drying. Screen printing: A photosensitive resin is applied to the metal surface, and then a pattern is printed onto the metal using screen printing technology. After printing, the pattern is dried. Etching: The printed metal workpiece is immersed in an etching solution, where a chemical reaction removes the unprotected material, forming the pattern. Post-treatment: This includes washing, ink removal, washing, pickling, washing, and electrolytic polishing.

[0004] As a key equipment in the etching process, the sealing performance of the etching box directly affects the etching effect and environmental performance. The operator usually opens the top cover of the etching box, places the metal crafts inside the etching line, and then covers the lid and etches them. However, if there is a certain gap between the lid and the etching box body, waste gas and wastewater are easy to leak through the gap, thereby polluting the environment. Therefore, it is necessary to propose an environmentally friendly etching device for metal crafts to solve the above problems. Utility Model Content
