The question of which processing method to use for micropore mainly depends on which process to use. Yaodafa Precision mainly uses etching process and laser cutting process to process micro holes. The specific hole density is high, and the holes are uniform without burrs. Other processes can adopt electric spark and stamping, which are relatively rough and less accurate. Etching process is the preferred process to solve the small hole and micro hole processing of precision filter screen
Etching process: The material thickness determines which process must be used. Yaodafa precision etching process can well solve the problem of how to process precision micro holes and small holes. The main applications are: etching process. This process can effectively match the thickness of the materials used, and solve the problem of how to process precision micro holes and small holes. In particular, there is a unique processing method for some dense holes with high tolerance requirements. The processed 0.2mm hole wall is free of burrs, with uniform hole diameter and good roundness. When such dense or non dense microporous products require mass production, the etching process can also actively respond. Yaodafa uses a roll to roll glass exposure machine to produce etching products. The daily production is up to 1000 square meters. It greatly satisfies the high-end precision diameter micro hole etching processing problem.
When the etching process is used to solve the problem of how to process precision micro holes and small holes, the indispensable link needs to be limited by the material thickness. In general, when etching holes with a diameter of 0.2mm, the thickness of the material used must be 0.03-0.08mm or earlier. If the thickness is greater than 0.2mm, the etching process is not applicable to solve the problem of processing 0.2mm holes. Because, at this time, the expansion of chemical etching agent cannot meet the etching amount.
