Silicon Nitride Ceramic:
The main purpose of the copper insert is to inject the product into some plastic parts, which can form an effective internal thread in the plastic part after installation. The operation method is to embed the product into the plastic part after heating or directly use the mold for injection. Because brass has good thermal conductivity, pressing the copper insert into the plastic matrix after heating can quickly heat the product and speed up work efficiency. The heated copper insert can also quickly conduct heat to the plastic part, thereby making the plastic The periphery of the hole becomes soft, thereby quickly pressing the product into the hole. If mold injection is used, after the copper insert is heat-injected into the plastic part, due to the embossing process on the outer diameter, it will form a certain friction and bite force with the copper insert High Precision Ceramic Network Resistor Substrate Plate after forming, which can be fixed inside so that it cannot fall off.
