Seamless welding process


Chengli company's sprinkler seamless welding technology. The welding device converts the current 50 / 60Hz electrical frequency into 20KHz or 40KHz high-frequency power through a transistor function device and supplies it to the converter. The converter converts electrical energy into mechanical vibration energy for ultrasonic waves, and the pressure regulating device is responsible for transmitting the converted mechanical energy to the welding head of the ultrasonic welding machine.
Welding head is an acoustic device that directly transmits mechanical vibration energy to the product to be laminated. Vibration is transmitted to the bonding surface through the welding work piece. Vibration friction generates heat energy to melt the plastic. Holding the pressure for a short time can cause the melt to produce a strong molecular bond when the adhesive surface is solidified. The entire cycle is usually completed in less than one second, but its welding strength is close to a connected material.
Seamless welding technology can not only help eliminate mold welding seams, but also improve the accuracy, finish and appearance of parts accordingly. At the same time, seamless welding technology implements efficient control during the injection molding process, shortening the processing cycle of the mold. Because the products produced by this process have excellent surface finish, secondary spraying and annealing are not required, and dimensional changes due to secondary shrinkage are avoided.
