Clamps polishing, is a very important part, but generally when the factory produced, are used in the more traditional way of polishing, there is now a lot of new processing methods, electrochemical polishing is one of them today give you a brief introduction. Pros: up to mirror gloss, long-term, process stability, less pollution, low cost, pollution prevention and good. Inadequate: a one-time investment in large, complex parts to be installed tooling, auxiliary electrode, mass production to lower the temperature. Applications: dirty block products, require long time to keep the mirror light, bright products. Process is stable, easy to operate, can be widely used. Stainless steel clamps colored stainless steel products not only given to a variety of colors, variety of products, but also can improve product wear and wear resistance. Stainless steel clamps coloring methods are summarized as follows: (1) ion deposition oxide or oxide (2) high-temperature oxidation (3) chemical oxidation (4) production of gas-phase pyrolysis process is very important to peroxide crosslinked EPDM rubber can be used under harsh conditions. EPDM rubber in ozone concentration 50pphm, stretching under the condition of 30%, up more than 150h does not crack. In the long-term effects of acid concentration also decreased performance.
