35Khz 500w Handheld ultrasonic spot welding machine for nonwoven/fabric/cloth welding

Parameter

Description

Ultrasonic hand-held spot welders actually belong to the category of ultrasonic welding, which uses ultrasonic waves to generate high-frequency vibrations to weld two materials, metal or plastic, together. For hot-formed parts without assembly contours, or parts whose geometry and actual conditions exclude the possibility of standard welding operations, ultrasonic spot welding is relatively more suitable for processing.

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.

Ultrasound is a mechanical vibration, similar to the vibration produced by musical instruments. These vibrations are called ultrasonic waves because their frequency is higher than human hearing (greater than 16 kHz). In the acoustic component, these pressure waves are generated by a generator. This will send alternating current at the same frequency as the converter (or transducer). Then, a transducer made of piezoelectric ceramics converts this energy into mechanical vibration. Then, mechanical vibration will generate thermal friction, which will stimulate the molecules of the material being welded to start moving. Ultrasonic energy will melt the contact points between the two parts, thereby forming a joint, allowing the parts to bond quickly.

The spot welding machine is suitable for those components that do not need to weld the entire welding path at the same time. It is light in weight and easy to use, and can be used in outdoor scenes. Spot welding machine has high versatility, flexibility and cost-effectiveness, so it still has strong competitiveness in various welding fields.

Features

Maximize efficiency

Ultrasonic welding is monitored through time, energy, power and height limits, and the entire welding process is tested in real time, so as to maximize the efficiency of the entire welding process and minimize the energy consumption of production.

Cost saving and environmental protection

The entire welding process is clean and pollution-free, because no harmful solvents or adhesives are used during the welding process, and the product itself will not be damaged, which avoids some of the problems of traditional welding and bonding processes and saves welding costs. Due to its complete electrical characteristics, this technology does not require high-level maintenance.

Speed ​​advantage

The typical welding cycle is within 0.5 seconds. Compared with other welding methods, the welding speed is faster. This welding technique is much faster than traditional adhesives or solvents. The cooling time is very fast, and the workpiece does not need to be left in the tool for a long time to dry or solidify the welded joint.

Easy to operate

The general ultrasonic spot welding equipment is a small machine, which is relatively light to operate and does not require high manual technology. It is convenient to store after use and does not take up a lot of space. Ergonomics and lightweight handheld probe can reduce operator fatigue. The lightweight system with integrated handle makes the device easy to move and easy to move in the factory.

High welding accuracy

High-precision thrust control and highly accurate welding depth control ensure the overall welding quality and avoid weak welding. Ensure a certain welding quality and avoid burning or burning of materials.
