Wire Threaded Inserts Coating With Silver Cadmium Tn And Zinc For Different Purposes
Information
1. The surface coating can be used for the surface treatment of different specifications and different purposes. It can be plated with silver, cadmium, tin and zinc.
2. The surface coating Thread Inserts is selected according to the specific requirements of the service environment. High temperature environment (aircraft engine) choose silver plating, eliminate potential difference (ship, radio wave) choose cadmium plating.
3. At the same time, it has all the functions of conventional Thread Inserts.

Advantage
1. Wire thread inserts are used in various low-strength materials, which can greatly improve the wear resistance of screw connections and avoid damage to the connecting threads.
2. Due to the certain elasticity of the wire thread insert, the load distribution on each circle of the thread can be more even, the pitch and tooth form deviation between the screw and the screw hole can be eliminated, and vibration can be absorbed, thus improving the connection strength and resistance Fatigue strength.
3. The locking wire thread insert can lock the screw in the threaded hole, so that the screw will not loosen when it is subjected to shock and vibration, and the process performance is better than that of the usual locking device.
4. Compared with the method of inserting steel or copper bushings, under the same strength conditions, screws with smaller size and higher strength can be selected, which can reduce the volume and reduce the weight.
5. The hardness of the wire thread insert is higher than that of the screw, so it is less worn during the assembly and disassembly process of the screw connection and can be used repeatedly. According to relevant experimental studies, the tensile strength of the wire thread insert is more than 7 times that of the screw, so the wire thread insert will not be damaged even if the screw is broken.
Application
In addition to aerospace and military use, wire thread inserts are also widely used in civil products such as railway transportation, construction machinery, textile machinery, medical equipment, papermaking, weapons, radar, rockets, ships, steam turbines, and chemicals. In foreign countries, it is not only used in aircraft and aerospace industries, but also in industries such as ships, automobiles, machine tools, motors, textile machinery, and instrumentation. Even in light industrial products such as cameras, sewing machines, and modular furniture, this kind of silk cover is widely used.
