Principle of ultrasonic spot welding machine
The ultrasonic hand welder transmits ultrasonic energy to the welding area through the upper weldment. Due to the large acoustic resistance of the welding area, that is, the interface between the two welding, local high temperature will be generated. In addition, due to the poor thermal conductivity of the plastic, it cannot be distributed in time, and it gathers in the welding area, causing the contact surface of the two plastics to melt rapidly. When the ultrasonic wave stops working, let the pressure continue for a few seconds to make it solidify and form, thus forming a strong molecular chain to achieve the purpose of welding, and the welding strength can be close to the strength of the raw materials.

Handheld ultrasonic spot welding machine: It belongs to a small ultrasonic plastic spot welding equipment, also known as ultrasonic plastic spot welding machine, ultrasonic spot welding machine, etc. It is suitable for use in various products: spot welding, riveting welding, riveting point, Welding, welding and other processes.

The ultrasonic welding horn is transmitted to the plastic processing parts, so that the two plastic joints have strong friction due to the action of ultrasonic waves, and the frictional heat melts the plastic joints and completely joins them. This technology has the characteristics of high speed, strong welding, and more importantly, it can automate the processing of plastic products. The ultrasonic plastic welding machine can weld plastic, insert, form, riveting, welding, cutting, stitching and other operations, and can do various applications on the machine just by changing the welding head.

Advantages of ultrasonic spot welding
High stability: The digital electric box automatically tracks the resonant frequency and adjusts the output frequency to match the handheld device. Once found, the fault stops working and alarms, and most ultrasonic welding can be completed within 0.1-0.5 seconds.
Energy saving and environmental protection: The welding surface is not damaged or deformed, there is no scratches and glue residues, and a large number of fixtures, fluxes and glues are not used, which reduces labor and costs.
Reliable quality:Ultrasonic welding solidifies and forms, and the molecules are recombined to form a solid molecular chain. The strength of the weld can be close to the strength of the raw material, and the air tightness is good, watertight and airtight. .
Simple operation: Ultrasonic welding is very easy to automate. As long as the welding parameters are set, the welding can be carried out without preheating or cleaning.
Wide range of applications: Handheld ultrasonic spot welding machine can be used for welding, riveting, spot welding of films, fabrics, thermoplastic products, as well as inlaying and blanking processes between metal parts and plastic parts.

Ultrasonic welding application fields


Ultrasonic hand-held spot welding machine is suitable for industries: plastic, toys, clothing, electronics, electrical appliances, auto parts, packaging, environmental protection, medical machinery, small area heating and small work surface design, light body, lengthened linear bearings make the machine High movement stability, suitable for welding precise workpieces.
