cosmetic bottle caps with an annual output of 3 millionAbstractChina's cosmetics market is the largest emerging market in the world.In 2019,the retailsales per unit above the limit of cosmetics in China reached 299.2 billion yuan,and the outputof cosmetics was 124 tons.There are more and more cosmetics companies every year.Thereare also a variety of cosmetic packaging on the market.This design is a gold imitationelectroplating process for plastic cosmetic bottle caps.Since the first World War,thegalvanizing process has been widely used,and the electroplating process has beencomprehensively developed and studied.At present,the common electroplating process onthe market is cyanide containing electroplating,which has obvious disadvantages of too muchpollution.After a lot of literature review and research In this process,cyanide free coke zeroacid salt system is adopted for electroplating,which greatly reduces the pollution.The maincontents of this design include formula design,process flow design,material balance,equipment selection,workshop layout,cost accounting and three wastes treatment.Keywords:Imitation gold plating:pyrophosphate:workshop layout:hanging appliances目录1前言1
