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.
Production Process:
1. The material of the roller body is generally selected from high-quality seamless steel tubes (special materials can be customized according to user needs). After boring and grinding the inner hole, the thickness of the tube wall is uniform, and then it is made by welding, stress relief treatment, turning, grinding, and finishing;
2. Correct the static balance and dynamic balance treatment; the coaxiality of the finished roller ≤0.02mm;
3. According to the pattern, different processing techniques are adopted to achieve a clear pattern, exquisite pattern, rich levels and precise size of the extruded product.
4. The final surface is plated with hard chrome or other treatments, and the hardness can reach HRC58-62.
