28kHz Portable Ultrasonic Spot Welding Machine for Car Repair, Ultrasonic Spot Welding Machine, Portable Ultrasonic Welder

Welding principle of auto parts: An ultrasonic generator converts 50/60 Hz current into 15, 20, 30 or 40 kHz electric energy. The converted high-frequency electric energy is again converted into mechanical motion of the same frequency through the transducer, and then the mechanical motion is transmitted to the welding head through a set of amplitude modulator devices that can change the amplitude.

The welding head is used to act on the plastic product workpiece, and the temperature of the transfer to the interface is increased by the friction between the surface of the workpiece and the internal molecular parts. When the temperature reaches the melting point of the workpiece itself, the interface of the workpiece is quickly melted, and then the interface is filled When the vibration stops, the workpiece is cooled and shaped under a certain pressure of the ultrasonic spot welding head at the same time, and a perfect welding is achieved. Ultrasonic plastic welding machine can perform plastic welding, embedding, forming, riveting, electric welding, cutting, stitching and other operations. It can be used for multiple applications only by changing the welding head.

Spot welding can be used for ultrasonic strong spot welding on soft plastic sheets such as ABS, polyethylene, polypropylene, and PVC. The specially designed projection head is used to enhance the welding strength and appearance. Ultrasonic spot welding replaces adhesives, rivets, staples and other mechanical fasteners. This process is used to assemble trailer bodies, car defroster pipes, furniture and other large thermoplastic parts. Using portable handheld tools and a multi-head automation system, many welds can be performed at the same time.

Features

Compared with the traditional technology (such as gluing, electric perm or screw fastening, etc.), the handheld ultrasonic spot welding machine has significant advantages such as high production efficiency, good welding quality, environmental protection and energy saving. The handheld ultrasonic welding machine can also be used for welding and riveting of thermoplastic products, as well as the embedding and edge pressing process between metal parts and plastic parts. It has completely replaced the organic baking point agent paste process, and has the characteristics of low energy consumption, high efficiency, no deformation, no pollution, firm welding, and convenient operation.

Ultrasound can be used not only to weld metals, hard thermoplastics, but also to process fabrics and films. The handheld ultrasonic welding machine can replace different ultrasonic welding heads according to the size of the riveting point and welding requirements of the product to be welded. It is fast and convenient, and the cost is much lower than that of the special ultrasonic welding machine for car door panels. It meets the needs of customers. .

The product is small in size, simple to operate, and quick to clean: it adopts modular integrated circuits and has strong power output: built-in automatic protection circuit, safe to use, stable and reliable in work. The welding surface is firm, high-strength, beautiful and ring-like

Save. According to the riveting point size and welding requirements of the product to be welded, different ultrasonic welding heads can be replaced, which is fast and convenient.
