Pinch Cylinder Embossing Flexo Printing Hot Printing Roller

Embossing roller is suitable for pressing concave and convex patterns such as plastic sheet, film, aluminum foil, leather, hard board, wallpaper, floor tile, glass, paper, etc., to improve the product surface aesthetics, strengthen anti-counterfeiting, trademark protection and other effects. And according to customer requirements to develop different patterns of embossing rollers.

Etching technology

Treatment technology for removing metal from the metal surface by using the erosion effect on the metal surface. In this way, various patterns are formed on the metal surface, which is called etching processing, and the mold industry is called erosion processing, also called bite processing or "corrosion processing".

l Electrolytic etching

The mother mold is used as the conductive cathode, and the electrolyte is used as the medium, and the erosion removal method of etching is concentrated on the processed part.

l Chemical etching

Using chemical resistant coating to remove etching corrosion and concentrate on the desired parts.

Photo-etching process (photo-etching process) uniformly forms a layered photoactive chemical resistant film on the metal surface, and then passes through the original film, exposes it with ultraviolet rays, etc., and then applies a development process. Form the coating layer of the chemical resistant coating of the desired shape, and then use the acid or alkali solution of the etching bath to chemically or electrochemically etch the exposed portion to dissolve the gold

Is a processing technology.

* Characteristics of etching technology

1. There is no need for tools such as electrodes and master, so there is no need to maintain these tools.
2. The time required from planning to production is short and can be processed for short periods.
3. The physical and mechanical properties of the material are not affected by the processing.
4. Processing is not restricted by shape, area and weight.
5. Processing is not limited by hardness and brittleness.
6. Can process all metals (iron, stainless steel, aluminum alloy, copper alloy, nickel alloy, titanium, alloy).
7. High-precision processing.
8. Can apply complex, irregular and discontinuous design and processing.
9. Large area and good processing efficiency, but when the area is small, its efficiency is worse than mechanical machining.
10. The horizontal cutting is easy to obtain high precision, but the depth and vertical directions are not easy to obtain the same machine machining accuracy.
11. The composition and structure of the processed object should be uniform, and it is not easy to process the uneven material.
