Flexible control of high frequency output is a Yamamoto Vinita original technology. Customers can choose the optimum control pattern according to the type and shape of film to be welded and the application the welded film is to be used for.

Power control involves both hybrid heating of the high-frequency metal molds by a heater and cooling by forced air. Yamamoto Vinita has a proven track record and extensive experience in all stages of production that require high-precision control.

Welding involves three important factors – balance must be maintained between the high-frequency metal molds (electrodes), the density of the heated object located between the high-frequency metal molds must be constant, and the thickness of the film must be regulated to the required uniform value. Cooling and curing by maintaining pressure for a fixed time after stopping high-frequency output also are key factors.

Yamamoto Vinita provides an evolved servo drive system to ensure that torque and welded film thickness can be accurately controlled and linearly monitored.

In welders, the high-frequency output time and cooling time must be controlled, and power and pressure must be linked to control timing. Heating power is determined by multiplying power by time. Yamamoto Vinita welders incorporate a technology for freely controlling even the speed at which preset output is reached to ensure stable welding quality in a variety of films.
