Processing methods for small hole meshes less than 0.5mm.

If you need to machine a small hole with a diameter of less than 0.5mm on a metal foil, there are generally three processing methods: wire cutting process, laser process and metal etching process. So what are the characteristics of the above three processes, and what is the processing of small holes with a diameter of 0.5mm or less? Let's sort out the analysis for everyone.

          1. Wire cutting process: generally called electric wire cutting, it is a process of melting and oxidizing local metal by the instantaneous high temperature of electric spark. The hole of this process is less than 0.5mm, and the periphery of the hole is There will be some oil pollution; in addition, he needs to use slow wire cutting to obtain higher precision, there will be some burrs at the junction of the lower knife edge and the knife edge, which needs to be processed, and the efficiency is not high; for the processing of ultra-thin metal materials Limited

          2. Laser processing of holes below 0.5mm is faster than wire cutting. However, there are also some deficiencies in processing, such as the edge treatment of the lower knife and the knife edge. Since the laser burns the material by the light temperature, it is easy to leave a residue around the aperture, and the color of the residue is black, and it is difficult to clean. The smallest holes for laser machining can reach 0.1 mm or even smaller holes. However, the presence of wavy lines is the biggest drawback after magnifying N times. In addition, laser processing of holes below 0.5mm is easy to change the properties of the material through high temperature, and is easy to affect the materials of some special materials;

          3, metal etching process: the process for the processing of small hole diameter and material thickness are mutually restrained, such as 0.5mm aperture, material thickness is less than 0.5mm; 0.2 aperture thickness is less than 0.2mm. However, the metal etching process is ideal for processing a number of dense, high tolerance hole meshes. The processed small hole wall has no burrs, uniform pore size, and good roundness, and can also meet batch scale production. Xin Haisen is a professional micro-hole etching processing manufacturer with a hole diameter of 0.03mm and a roll-to-roll etching equipment. The daily amount can reach 5000m2.

  The above is the introduction of the processing methods for the small-hole mesh with a diameter of 0.5mm or less. You can select the corresponding process according to the specific requirements of the product.
