This article mainly talks about the classification of copper nuts. What kinds of nuts are there? If you want to know more about non-standard parts, please come to our company website for more information. Please read the following:brass fitting pipe connector
Embedded knurled copper nuts, also known as knurled copper inserts, are mainly used with hexagonal copper screw, copper column, copper screw and other copper products to tighten the connection of other materials, which belongs to the copper standard fastener series.
The main purpose of copper inserts (copper nuts) is to pre-embedded products in some plastic parts, which can form an effective internal thread after installation. Because brass has good thermal conductivity, pressing the copper insert into the plastic matrix after heating can quickly heat the product and speed up the work efficiency. The heated copper insert can also quickly transmit heat to the plastic parts, thus softening the periphery of the plastic hole, thus quickly pressing the product into the hole.
If injection moulds are used, copper inserts are pre-embedded in plastic parts by heat. Because of the rolling and embossing process in the outer diameter, a certain friction and biting force are formed between the copper inserts and the formed copper inserts, which can be fixed in the plastic shell without falling off. The method of operation is to heat the product and insert it into the plastic parts or directly use the injection mould.
The surface of the embedded parts of the ultrasonic nuts of copper inserts is straight thread and twill corrugated copper nuts. It is the same as the principle of the embedded nuts of hot pressing. The difference is that the embedded parts are pre-embedded with plastic melting or softening by heating the copper nuts. The ultrasonic copper nuts are embedded with plastic melting or softening by means of high frequency ultrasonic vibration.
