1. Ultra-High Precision Etching Technology
Photochemical machining (PCM) is a precision metalworking technology based on photolithography and chemical etching. It boasts a dimensional tolerance of ±0.01mm, achieving exceptionally high geometric accuracy and edge finish. This process is particularly well-suited for machining ultra-thin metal sheets, with thicknesses as low as 0.02mm. It can produce complex patterns and microstructures without the need for die stamping, and is widely used in applications requiring the highest precision and surface quality.

3. Precision Applications in Multiple Industries
In medical device microstructure fabrication, photochemical etching can be used to manufacture implant scaffolds, meshes, and microneedle arrays. In 5G communications and semiconductor components, it is suitable for the high-precision fabrication of shielding covers, connectors, and heat dissipation elements. In the battery and new energy sectors, this process can be used to process highly conductive electrodes, busbars, and battery connectors, ensuring electrical performance and consistency.
4. Flexible Etching Depth Control
The PCM process not only supports localized etching but also achieves gradient etching depth, creating zones of varying thickness based on functional requirements to meet design requirements for conductivity, heat dissipation, or flexible structures. Furthermore, continuous etching of metal coils can be employed, significantly improving production efficiency and ensuring dimensional consistency, making it ideal for industrial manufacturing requiring high production volumes and consistent quality.
5. One-Stop Solution for Large and Small Batch Production
The photochemical etching process supports both large-scale automated production and rapid small-batch prototyping, eliminating the need for expensive tooling, offering short lead times and high repeatability. Combined with subsequent electroplating, forming, welding, and assembly processes, it provides customers with a one-stop precision metal processing solution, enabling efficient innovation and high-quality manufacturing in the high-end electronics, medical, and new energy industries.
