The amount of heat can be reduced to less than half of that of general TIG, so you can start repairing overlay cladding with less installation cost and space than with laser welding machines!
It is also equipped with a resistance spot welding function, so it is effective for temporary fixing of fine wires and attaching shim plates!

Plastic molds: repairing parting lines, apex angles, and pinholes

Press molds: Raising the bottom of nests, repairing cutting edges, attaching shim plates

Die-casting molds: Repair cracks, build up worn parts

Rubber mold: repair of cutting edge, repair of loose corner

Glass mold: build-up of worn parts
The name of Item[2] Ultrasonic lapper LAPTRON ALLIIIR
Details[2]

LAPTRON ultrasonic polishing and polishing solves the problem of discharged eyes and back corners that are difficult to polish by hand or with air tools!
The LAPTRON ALLIIIR, which incorporates the advantages of 50 years of ultrasonic polishing machines, can handle a variety of parts in a single machine!

With a maximum movement range of 50 μm, this range of 18,000 to 26,000 movements per second allows you to polish without moving the hand tool by hand.

In addition, it is equipped with a rotary tool that uses a rubber grinding wheel, so you can switch between ultrasonic and rotary operations with a single touch, even when you want to increase the radius or polishing width, without taking up any work space.
