Machinary Purity Si3N4 Silicon Carbide Nitride Ceramic Groove Tube Rod Pins

1 . Descriptions:

Silicon nitride positioning pins are similar to ordinary welding positioning pins, except that they are made of superhard silicon nitride ceramics. The special physical and chemical properties of silicon nitride ceramic materials determine some special properties of silicon nitride positioning pins. For example, high wear resistance, high hardness, non-conductive, non-magnetic, non-adhesive welding slag and other excellent properties.

2 .The difference between silicon nitride locating pins and locating pins made of other materials:

3.Projection welding (spot welding) silicon nitride locating pins are used to weld the metal nut to the precise position of the metal plate. The silicon nitride locating pins are mainly made of silicon nitride with high strength, wear resistance and corrosion resistance of molten metal ( Silicon nitride ceramics have a very large contact angle with metal and almost no chemical reaction) and insulation. Silicon nitride positioning pins are very suitable for use as projection welding (spot welding), because if you do not use insulating silicon nitride positioning pins during welding, unnecessary current will pass through, causing sparks between the pins and the workpiece, resulting in The wear of the pin leads to the inability to locate, which reduces the quality and pass rate of the workpiece. And due to sparks, the workpiece often requires an additional through-hole process. At present, the silicon nitride projection welding (spot welding) positioning pin has been applied in batches in large domestic auto parts factories, and the comprehensive cost performance is 70 times that of steel positioning pins.
