Flat washer supplier, the three magic weapons of flat washer processing technology [hardware]

In order to meet customer requirements, flat washer suppliers usually have post-processing techniques for flat washers. Generally refers to the process of forming a covering layer on the surface through some processes. Xiao Shuo takes you to understand the three magic weapons of the next surface treatment: 1. One magic weapon: the electroplating of flat washers. The electroplating of flat washers refers to immersing the part of the fastener that needs to be electroplated into a specific aqueous solution, which will contain Some deposited metal compounds, so that after the current passes through the aqueous solution, the metal substances in the solution precipitate and adhere to the immersed part of the fastener. Electroplating of fasteners generally includes zinc plating, copper, nickel, chromium, copper-nickel alloys, etc. 2. Two magic weapons: hot-dip galvanizing of flat gaskets hot-dip galvanizing of flat gaskets is to immerse the blow molded abrasive fasteners of carbon steel component into the plating tank of molten zinc with a heat of about 510℃. The iron-zinc alloy on the surface of the fastener will be transformed into passivated zinc to obtain the surface treatment effect. The price of hot-dip galvanizing of fasteners is higher than that of electroplating, about 1.5 to 2 yuan per kilogram. 3. Three magic weapons: mechanical plating of flat washers. Mechanical plating of flat washers refers to the use of specific physical and chemical means to impact the surface of the fastener with the powder of the plated metal, so that the plated metal is cold welded. A coating is formed on the surface of the fastener to achieve a surface treatment effect. The mechanical plating of fasteners is mainly applicable to spare parts such as screws, nuts and washers. Hardware, 15 years of ingenuity and focus on flat washer suppliers, custom production of 20000+ sets of molds, monthly processing capacity of 100+ sets of stamping dies, daily production capacity of 3 million punching times, stamping accuracy up to 0.01mm, and 16 quality inspections. . It can quickly solve time-critical problems, solve stamping accuracy problems, and solve quality problems for you. Choose, choose rest assured!
