| titleOfInvention | Production process of cast iron copper-imitation well cover |
| abstract | The invention provides a production process of a cast iron copper-imitation well lid, which comprises the following steps: the method comprises the following steps: processing a panel mould through a customized pattern machine tool, and then producing a cast iron well lid blank; step two: processing, polishing and repairing a blank, removing oil from the blank, removing a release agent, and quenching; step three: blackening the bottom layer by using a surface chemical agent, cleaning, drying and polishing; step four: carrying out copper imitation treatment; step five: cleaning and drying again; step six: customizing and processing the raw materials into color effects required by customers, drying the raw materials at high temperature, and spraying a surface sealing agent; step seven: drying at high temperature, cooling, inspecting, packaging and warehousing. The invention is the most economic and best imitation copper process effect in the market, the well cover has the same effect as pure copper before the surface is not scratched, and the steel wire mesh barrel is laid between the imitation copper layer and the well cover, so that the connection between the well cover and the imitation copper layer is more compact and firm, the strength of the well cover is improved, the imitation copper layer is not easy to drop, and the service life is long. |
