Process and benefits of photo etching
December 5, 2020
Photo etching is one of the enhanced technologies used for the fabrication of sheet metal works. You can also describe the photo etching process as the photochemical machining process that can provide works with high accuracy. The metal stamping process during earlier years was not an easy task before. Errors and difficulties during the fabrication of sheet metal works can create a loss of money and time. You can reduce this trouble by utilizing the etching process in the metal sheet fabrication works.
You can use a wide range of metals for the process of photo etching process works. Before preparing any one of the metals for the stamping process, make sure that the preferred metal is compatible with the etching process. The selection of the metal for the fabrication and stamping process is made by the customers. Customized designs are generally made for the photo etching process to get the required results with high accuracy. Blur-free fabricated sheet is one of the main factors considered to ensure the quality of products. The use of the photo etching process for the fabrication works assure stamped metal with a smooth and glossy finish touch.
The designs for the photo etching process can be customized as per the requirement of the customer. Thin photographic films of the required length and designs are prepared generally to do stamping on the metal works of the plates. The photo etching process is not done in an easy and single procedure. The final product of the fabricated and stamped metal is obtained after undergoing a series of stages. Cutting the metal to the desired length is the primary stage done during the etching process of the metal works.
The metal sheet after the cutting works are cleaned thoroughly to reduce the occurrence of grease and oil in the metal parts. After the thorough cleaning process of the metals, the portion of the metal sheets that need to be etched is provided for the coating procedures. Printing works on the required metal portion is done by the application of pressure on the metal parts. The printed metal is then provided for further development procedures to make the final metal portion smooth and exotic.
UV rays are generally exposed to the metal portions that need to be printed for the etching process. The portion exposed to UV rays generally becomes harder whereas the other portion becomes softer during the printing stage of the metal sheets. The acid used for the etching process is added with the required constituents and pressurized to complete the final etching process of the metal works. At present, many of the manufacturing companies for the making of industrial machine parts are utilizing the etching process to finish the task in superb quality.
