The horizontal etching machine production line is a critical piece of equipment in industrial manufacturing for metal etching, with widespread applications particularly in electronics, communications, and automotive industries. This production line employs acidic or alkaline etching solutions to chemically corrode metal surfaces, thereby achieving etched patterns, text, or graphics. Through the action of circulation pumps, the etching solution maintains uniform flow within the etching tank, ensuring consistent coverage of the metal surface. This precisely controls reaction time and conditions, enabling accurate regulation of etching depth and precision.
