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.
