The processing of filter mesh is the most common processed product in daily life, and its precision is also constantly increasing. In the early days, filter meshes were processed by punching and laser processing. The pursuit of thickness precision has become smaller and smaller, resulting in the pursuit of the ultimate process. The punched micron mesh has a limit on thickness.
The process requirements cannot be met if it is less than 1MM. Punching will cause material fracture and holes. High-precision laser processing can achieve a 1MM aperture. Due to the laser burning method, some holes will have black spots. Subsequent surface treatment is required, such as polishing or plating, nickel plating for anti-corrosion effect, etc. Laser processing is relatively slow in batch processing and production.
Therefore, if the precision requirements and micron tolerances are extremely small, it is processed by chemical etching, using the chemical composition of ferric chloride to fuse with water to produce a high concentration of chemical agents. In the early stage of chemical etching, the metal material is degreased and polished, and then a layer of photosensitive ink is rolled on to protect the part that is not decomposed by the chemical agent.
The part that needs to be decomposed is exposed, and the prepared metal film pattern is developed and exposed to the metal material, and then the chemical etching process is entered to remove the photosensitive ink to form the desired metal finished product.
Why is etching chosen for micron tolerance mesh? The main reason is that the micron tolerance mesh etching process meets the processing requirements. The micron tolerance mesh etching processing thickness is between 0.01MM-2MM. The micron tolerance mesh etching surface is smooth and burr-free, maintaining product performance and not deforming. The metal film can be modified arbitrarily without increasing the processing cost, while the cost of punching mesh processing in designing the mold is relatively high.
Therefore, the best processing method for micron tolerance mesh can be chemical etching. Considering the mass production process, the price is low and meets high standard precision processing.
