Copper nuts made of various embossed wires (usually lead brass, such as H59, 3604, 3602) are processed by precision automatic lathe. The reference standard of embedded knurled copper nuts comes from GB/T809, but the technical parameters of various embedded nuts produced by our company exceed the relevant indicators of national standards.

The main operation mode of embedded knurled copper nuts is injection moulding. After heating, they are embedded in plastic parts or directly moulded. If injection moulding is used, the melting point of PA/NYLOY/PET is above 200 degrees C. The temperature of embedded nuts increases rapidly after hot melting into plastic parts. After injection moulding, the plastic body quickly cools and crystallizes and hardens, for example. If the temperature of the insert nut is still high, it is possible to pour the copper nut into the contact area of the plastic parts and begin to loosen or crack. Therefore, copper nuts are used instead of carbon steel nuts in the injection moulding of embedded nuts.

Embedded copper nut's external thread knurling has two ways to form. One is to use copper raw material to form and then go to the equipment for production. Generally, the drawing pattern of this way is straight, the other is to use smooth copper material to directly tap teeth while embossing in the process of production. This way of processing can produce one. Some non-standard size of knurled copper nuts, embossed with copper nuts embossing shape can be selected by users, such as mesh, eight-character embossing, herringbone embossing and other patterns.
