Principle of ultrasonic spot welder:
Ultrasonic hand welder through the upper weldment will ultrasonic energy transfer to the weld area, due to the weld area that is the two welded interface acoustic resistance, and therefore will produce a local high temperature. And because of the poor thermal conductivity of plastic, a moment can not be distributed in a timely manner, gathered in the weld area, resulting in the contact surface of the two plastics quickly melted, plus a certain pressure, so that it fused into one. When the ultrasonic stop acting, let the pressure continue for a few seconds, so that the solidification of molding, so that the formation of a solid molecular chain, to achieve the purpose of welding, welding strength can be close to the strength of the raw material.
Ultrasonic welding applications:
Ultrasonic handheld spot welder applicable industries: plastics, toys, clothing, electronics, electrical appliances, automotive parts, packaging, environmental protection, medical equipment, the use of a small area of the heating and small table design, lightweight body, lengthened linear bearings to make the machine movement of the stability of the machine, suitable for welding precision workpieces.
Product features:
Ultrasonic spot welding compared to traditional processes (such as gluing, ironing or screw fastening, etc.), with high productivity, good welding quality, environmental protection and energy saving and other significant advantages. Portable ultrasonic welding machine is specialized in welding and riveting process for plastics, non-woven fabrics, leather products, chemical fiber cotton and so on. Has completely replaced the traditional organic melting agent paste process, with low energy consumption, high efficiency, no deformation, no pollution, welding solid, easy to operate and other advantages. Handheld ultrasonic welding machine can be welded according to the size of the riveting point of the product size and welding requirements, replacement of different ultrasonic welding head, both fast and convenient, and the cost is much lower relative to the dedicated automotive door panel ultrasonic welding machine.
Product principle:
Ultrasonic welding machine through the ultrasonic generator will be low current frequency into high frequency alternating current, the electrical energy into the ultrasonic transducer to produce the same frequency of mechanical movement. The mechanical movement is transmitted to the ultrasonic welding head through the amplitude modulator device, and the welding head transmits the received vibration energy to the joint of the workpiece to be welded. In the area of action, the energy is converted into heat by means of friction, melting the plastic. The short-lived pressure maintained on the workpiece after the vibration stops causes the two weldments to solidify as one in a molecularly linked manner. Typical welding time is less than 1 second and the resulting weld strength is comparable to that of the body.
Pistol type ultrasonic spot welder:
Shape in accordance with the ergonomic design, ultrasonic start switch is located in the pistol's trigger out, easy to lift and use, especially for horizontal or vertical welding operations.
Grip type ultrasonic spot welder:
The shape is straight design, the ultrasonic start switch is located on the outer side of the cylinder, easy to grip welding and carry, can also be installed between the machine equipment, suitable for welding operations in all directions.
