Introduction to the material selection of PIN needle and related wire drawing process:
Material selection of PIN needles:
At present, PIN pins are widely used in various connectors and have a broad market space. So do you know what material PIN needles are generally made of?
At present, most of the PIN pins on the market are made of "tungsten carbide". And because the PIN pin is used to complete the electrical (signal) conduction of the connector. Therefore, the material requirements of the PIN pin must be capable of transmitting electricity (signal). At the same time, since heat is easily generated during electrical (signal) conduction, the corresponding PIN needle must have sufficient heat resistance. On the other hand, because the PIN needle also plays a certain role in connection and needs to be pulled out and inserted frequently, the material of the PIN needle must be hard enough and have certain wear-resistant characteristics. In addition, since the PIN pin is used to conduct and connect electrical (signal), the material must be corrosion-resistant and melt-resistant enough to avoid affecting the use of the connector.
Therefore, the requirements of PIN for the production of materials are to have the effect of conduction (conduction/signal conduction), and have the characteristics of high temperature resistance, certain hardness, corrosion resistance and so on.
Introduction to PIN needle drawing process:
PIN needle drawing is a new surface treatment process, it is based on aluminum plate as the base material, under the action of external force to make the metal forcibly pass through the mold, the metal cross-sectional area is compressed, and obtain the required cross-sectional area shape and size of the technical processing method called wire drawing die, the wire drawing plate is based on the aluminum plate, with the use of performance, the surface color is bright, uniform, stable, durable, to meet the pursuit of high quality and fashion sense of consumers.
1. At present, it is usually made of diamond cloth wheel surface drawing, which is made by various chemical treatments such as pressing and roller coating;
2. It has the performance of use, the board has good sound absorption and sound insulation effects, and good fire performance;
3. The surface color is bright and uniform, with a strong sense of fashion, giving people a strong visual impact;
