This is used in the welding of mouldings and semi-finished products made of rigid thermoplastics such as PS, ABS, AS, Acrylic, PVC, Acetal, polycarbonate and nylon.   This technique can practically be applied in each and every area of the plastics processing industry.  Different fields include toys, communications, automotive, packaging, household goods, audio/video products, electronics, watches and many other industries.
Ultrasonic plastics welder can be incorporated into various automatic systems.   Custom-made and automatic machines are available according to different production needs.  We also provide tool horn and fixture making.


Rapid Welding

No solvent or adhesive is needed.  Welding can be done within split second.   No drying is required.  Items can be beautifully finished without any mark or protrusion left by adhesive.

No tuning is required

Equipped with the automatic frequency tracking system, no tuning of the machine is required.  Changing of horns becomes much easier and set up time much shortened.

Protecting Features

Electronic protection circuits minimize the damage caused by improper tooling set up and operation.  Built-in constant vibration amplitude control gives steady output power and better welding effect.

Auxiliary equipment, custom-made tool horns and fixtures are available.
