Ultrasonic spot welding is used predominantly when, for instance, flat mouldings without weld preparation (ED) have to be welded (e.g. semi-finished products, thermoformed, blow moulded, extruded and large-surface mouldings).
The tip of the sonotrode penetrates through the upper part into the lower part. Heat is produced on the contract surfaces of the mouldings, as a result of which the material is plasticised and welded. The expelled plastic flows upwards and forms a ring shaped elevation. The back of the lower part remains largely free of marks. The mouldings can be fixed appropriately by hold-downs or clamping devices. The thickness of the moulding adjacent to the sonotrode should not exceed 8 mm. Spot welding can also be carried out with a moveable ultrasonic hand welding apparatus (welding gun).
Auto parts welding principle: The 50/60 Hz current is converted into 15, 20, 30 or 40 kHz electrical energy by an ultrasonic generator. The converted high-frequency electrical energy is converted into mechanical motion of the same frequency again by 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.
Using the welding head to act on the workpiece of plastic products, the temperature transmitted to the interface increases through the friction of 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 melts rapidly, and then fills the interface. When the vibration stops, the workpiece is cooled and shaped under a certain pressure of the ultrasonic spot welding head, so as to achieve perfect welding. The ultrasonic plastic welding machine can perform plastic welding, embedding, forming, riveting, electric welding, cutting, sewing and other operations. It can be used for multiple applications only by changing the welding head.
Principle of auto parts spot welding machine: Plastic spot welding machine is a hand-held design, generally used for plastic spot welding, plastic riveting and plastic chain welding, such as spot welding of plastic parts and plastic parts, riveting welding of plastic parts and plastic parts , Spot welding of plastic parts and non-woven fabrics, riveting welding of plastic parts and metal parts, etc.
Mainly used in two fields of auto parts and household appliances: car door panels, car sound insulation panels, car sound insulation felts, non-woven sound insulation cotton, TV casings, computer casings, electrical plastic trims, non-woven products, stationery spot welding, Mobile phone accessories, riveting of electrical devices, car dashboards, car signs, folder positioning, car bumpers, car manual gear covers, car inner guards, car felt pads, car floor mats, car dashboards, etc.
