Resistance welding is a method in which the welding works are heated by resistance heat generated by sandwiching the welding workpieces with welding electrodes, passing current through them, and the metal is welded while pressurizing the works.
We offer a wide variety of welding power supplies and welding heads to meet wide variety of welding workpieces.

• Resistance Welding

Because heating and cooling are done while the pressure is being applied, lifting up can be prevented, and therefore, most suitable for thermo-compression bonding of flexible circuits or wires, soldering or heat fusing of plastic objects.
It is superior in reproducibility of temperature and time, and as a result, variation of production quality by the operator can be minimized.
Because of local and instantaneous heating, thermal effect to the peripheral areas can be restrained. It is Pb free compliant.

• Pulse Heat Unit (Hot Bar Bonder)

It is an equipment to hermetically seal the packages, such as the crystal and SAW devices, optical devices, sensors, MEMS, etc., by seam welding.
Hermetic sealing can be accomplished in both N2 and vacuum environment.
Furthermore, we are offering a variety of products for research and development and production applications.

• Parallel Seam Sealers

It is an equipment to solder or weld plastics by the laser beam.
Micro joining is achieved by utilizing the high energy of a laser beam.

• Laser Welder

Resin (plastic) is instantly welded using sonic vibration.
In addition to being used as a single unit, we also offer models that match the intended use, such as built-in automatic machines and handy types.

• Ultrasonic Welding

Instantly joins materials that are difficult to bond by resistance welding, such as aluminum and copper. Models with output from 600W to 5000W are available.

• Ultrasonic Metal Welding

High-frequency induction heater unit is a high frequency generator for non-contact heating of metal using electromagnetic induction.

Metal induction heated screws and nuts can be easily and securely inserted into molded plastic components.

• High-frequency Induction Heater Unit

We are offering a variety of monitoring equipment for current, voltage, pressure and displacement which is indispensable for quality control of precision micro joining.
