Product Description
Photochemical Machining (PCM) is a stress-free process based on photolithography and chemical etching. Unlike traditional mechanical cutting, stamping, or laser processing, PCM does not generate thermal or mechanical stress, enabling high-precision contour forming while maintaining the metal's original mechanical properties. This technology eliminates stress concentration and deformation throughout the entire processing process, making it particularly suitable for the precision manufacturing of thin metal sheets (thicknesses ranging from 0.01mm to 1.0mm) and complex microstructured parts, ensuring high product flatness and excellent dimensional stability.

Photochemical machining technology is widely used in the manufacture of high-precision electronic components and the precision machining of aerospace structural parts. In the electronics industry, it is used to produce filter meshes, heat sinks, electrodes, shielding covers, and metal layers for flexible circuits. In the aerospace industry, PCM enables the high-precision manufacture of lightweight structural parts, nozzle orifice plates, microfluidic channels, and high-strength alloy sheets. Its high repeatability and consistency ensure that each component meets stringent functional and reliability standards.
This process utilizes high-resolution photoresist and double-sided exposure technology to achieve 10-micron pattern resolution. Advanced alignment systems and a constant temperature and humidity environment ensure ±5μm dimensional accuracy and edge control. The combination of photolithography mask precision and chemical etching uniformity enables perfect reproduction of complex geometries, fine gaps, and micropore arrays, ensuring product dimensional consistency and contour clarity.
