Product grade: grade 4.8

Product application: copper nut, also known as embedded nut and inlaid copper nut or plastic embedded nut, can be divided into hot-melt copper nut, hot pressed copper nut, embedded copper nut and ultrasonic copper nut according to different application methods

The product is widely used in the embedded parts of mobile phone shell / notebook shell / injection molded parts / plastic parts. It is used as an internal thread. Generally, the outer circle is embossed to prevent sliding.

Product features: another main use of copper nut is injection molding, which is embedded into plastic parts after heating or injection molding directly,

Hot pressed or cold pressed copper nut

Brass has good thermal conductivity. If the heated copper nut is embedded, on the one hand, the copper nut can quickly heat up and speed up the work efficiency. On the other hand, the heated copper nut can quickly transfer heat to the plastic parts, so as to soften the periphery of the plastic hole and facilitate pressing into the hole; So, what will be the effect if the injection mold is used? As we all know, the melting point of PA / nylon / pet is above 200 ° C. after the copper nut is hot melted into the plastic part, the temperature increases rapidly. After injection molding, the plastic body cools and hardens rapidly. If the copper nut temperature is still at high temperature, what will be the result? Smart you must have guessed that the result is that the place where the copper nut contacts the plastic part is loose or cracked. Therefore, copper nuts are used in injection molding instead of s
