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 method of operation is to heat the product and embed it in the plastic part 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 up 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 after forming, which can make it fixed inside so that it cannot fall off. Products are widely used in: mobile phones, laptop computers, a variety of plastic shells, communications, micro-motors, computers, electrical appliances, electronics, toys, watches, lighting, locomotives and other industries. The main types today are: CNC computer car parts, mobile phone nuts, embossed nuts, hot melt nuts, hot pressed nuts, embedded nuts, ultrasonic nuts, injection nuts, insert nuts, copper shafts, copper columns, copper sleeves, copper cups There are over ten thousand specifications in 20 categories, including screws, precision shafts and non-standard screws and nuts. Mainly include: environmental protection copper, H3604 copper, Japan 303 stainless steel, 24C easy-car iron, aluminum alloy, and steel.
properties:
High hardness, high strength, wear resistance, corrosion resistance, high temperature(1200°), good thermal diffusivity, good thermal shock resistance(avoid the temperature changing rapidly), good insulativity, low density. The comprehensive properties are best in most of structure ceramic.
