一. Characteristics of corrosion of chemical etching machine
1. The rigor of the process is relatively high and stable, and the protective layer is made by photo-solid method of photosensitive ink.
2. There will be no scratches, burrs or pitting on the corners.
3. Depth is free to control
4. The quality can be monitored, and the image transfer money processing link can judge whether there is any problem behind and reduce the scrap rate.
5. Surface attachments can be immediately cleaned to expose the substrate color
6. The pattern can be changed at any time according to customer's requirements. Single and double-sided shaped parts can be used at low cost.
7. The output is relatively high and can process a variety of metals
二.Characteristics of corrosion of electric corrosion machine
1. The process complexity is high, and it is necessary to align the workpiece
2. The corners of the electric etch are not smooth enough and there are burrs
3. If the depth is too low, it is not easy to control the depth.
4. The quality is uncontrollable. Only after it has been completely formed can it be judged whether it is good or not, and the scrap rate is high.
5. A layer of black substance adhered to the surface is difficult to clean, affecting the later coloring
6. The cost of the pattern change will be higher
7. Corrosion time is too slow, low yield
