Copper nut/brass bolts manufacturer

China cnc brass lathe turning part screw.As the name implies, brass fasteners are defined as nuts made of copper (usually lead brass, such as H59,H61).   Our daily contact with the copper nut is mainly hexagonal nuts or bolts matching other copper nuts.   

Our factory manufactures copper bolts /brass bolts . Message us (wholesale cnc brass parts manufacturer) to get cnc brass machined part quotes!

So why are copper nuts used in daily production activities?   Because copper nuts are not easy to rust, corrosion resistance, easy heat conduction and strong electrical conductivity and other advantages, generally used for rust prevention, high temperature, electrical conductivity and other use environment, such as water taps, valves, electrical switches and so on.   

Another major copper nut is the purpose of the injection molding, heated directly embedded into the plastic parts inside or mold injection molding, as previously mentioned, brass has good thermal conductivity, such as heating copper nut after embedding, on the one hand, copper nut can quickly heat up to speed up the working efficiency, on the other hand, copper nut can be quickly heated the heat conduction to plastic parts,   So that the plastic hole around the soft, easy to press into the hole;   So, if the use of mold injection molding effect will be what?   As we all know, the melting point of PA/NYLOY/PET is above 200°C, and the temperature of copper nut is rapidly increased after being hot melted into plastic parts. After injection molding, the plastic body is rapidly cooled and crystallized and hardened. If the temperature of copper nut is still at high temperature, what will be the result?   As a result, the copper nut is loose or cracked in contact with the plastic part.   Therefore, copper nuts rather than steel nuts are used for injection molding.   

The shape of the copper nut used in injection molding is generally round with various patterns, and the hot melting of the mold is generally cylindrical. The shape of the hot pressing or cold pressing copper screw has a certain taper or barbed shape. As for why it is conical or barbed.
