Copper nuts are usually made of lead brass, such as H59 and H62. Usually hexagonal nuts or other copper nuts matching bolts. Copper nuts are not easy to rust, anti-corrosion, easy to heat conduction and strong electrical conductivity. They are commonly used in rust-proof, low temperature, conductive, heat conductive and other application environments, such as taps, valves, electrical switches and so on. Another use is injection moulding, which is heated and embedded outside the plastic parts or indirectly moulded.
The shape of brass nuts used in injection moulding is usually round with various patterns, and the shape of hot-melt moulds is usually cylindrical. The shape of hot-pressed or cold-pressed brass nuts has a certain or taper with inverted thorns.
Knurled brass nuts are widely used in the following areas: notebook computer plastic shell, desktop computer plastic shell, GPS plastic shell, router plastic shell, mobile phone plastic shell, limited communication equipment plastic shell, household appliances plastic shell, automobile, electrical appliances, medical, electronic and other plastic shell.
The application of knurled brass nuts usually adopts hot melting, hot pressing, ultrasonic welding and injection molding pre-embedding, which make the products and plastic parts closely occlude and play the role of cohesion, locking and fastening.
