Copper-plated flat washers, tell you about the process characteristics of copper-plated [hardware]

Copper-plated flat washers are one of the more widely used flat washers. When you see the shiny golden flat washers, do you know some of the characteristics of copper plating? Xiaoshuo will take you to understand: The cyanide copper plating process is a kind of copper plating process with sodium cyanide as a complexing agent, which can directly obtain a good bonding force on the chemically active metal substrates such as steel and zinc alloy. The characteristics of cyanide copper plating solution: It has good dispersing ability and covering ability, fine degreasing ability, fine crystallization of the plating layer, suitable for the primer of steel parts and zinc and aluminum alloy products. Ordinary cyanide plating steel layer is not bright, flatness is relatively fluorescent, and the deposition rate is slow. When the plating layer reaches a considerable thickness, it will become rough, burrs and nodules appear. In order to increase the deposition rate and obtain a bright, smooth For a flat and thick chain layer, a high-energy cyanide copper plating solution added with Liu is usually used. According to the difference of bath composition and purpose. Cyanide copper plating solution can be divided into three types: primer type, potassium sodium tartrate type and bright type. Hardware, 15 years of ingenuity and focus on copper-plated flat washers, 20,000+ sets of stamping die customization production experience, monthly 100+ sets of mold processing capacity, 3 million punching production capacity per day, stamping accuracy up to 0.01mm, 16 quality inspections strictly for quality check. It can quickly solve time-critical problems for you, solve stamping accuracy problems, and solve production quality problems. Choose, choose rest assured!
