Molded-in threaded insert nuts embedding method
1, After the plastic is molded, it is first softened with high temperature, and then the copper nut is pressed into the mold to achieve embedding.
2, Another method is to place the copper nut into the mold before plastic molding, during the injection molding process, the plastic will encapsulate the copper nut, thus completing the embedding.
Heat staking threaded insert nuts embedding method
Hot melt copper nuts are made by heating copper nuts to a certain temperature using the principle of electrothermal melting, which softens the plastic and then presses them in.
They are particularly suitable for products that are difficult to weld, have irregular shapes, or are relatively large.
Nuts embedded in this way have excellent torque and tensile strength.
Cold-pressed threaded insert nuts embedding method
Cold-pressed copper nuts are widely used in injection molding processes. It’s a processing method performed at room temperature, where mechanical pressure forces the copper nut into a pre-drilled hole.
This installation method is simple and quick, requiring no heating and thus avoiding material deformation caused by high temperatures.
The cold-pressing process also improves production efficiency and reduces energy consumption.
