35kHz Portable Ultrasonic Spot Welding Machine for Auto Welding

                        35 Khz Portable Ultrasonic Spot Welding Machine  for Auto Welding        What's the principle of Ultrasonic plastic welding?       When ultrasonic act on the thermoplastic plastic contact surface, high-frequency vibrations of tens of thousands of times per second. This high-frequency vibration reaches a certain amplitude, and the ultrasonic energy is transmitted to the weld zone through the upper weldment, because the weld zone have a large acoustic resistance, so local high temperatures are generated. Moreover, due to the poor thermal conductivity of the plastic, it can not be dissipated in time and gather in the weld zone, so that the contact faces of the two plastics melt rapidly, and after a certain pressure, they are integrated into one. When the ultrasonic wave stops, let the pressure last for a few seconds to solidify it, thus forming a strong molecular chain for welding purposes, the welding strength can be close to the strength of the raw material.       The quality of ultrasonic plastic welding depends on the amplitude of the transducer welding head, the applied pressure and the welding time. The welding time and the welding head pressure can be adjusted. The amplitude is determined by the transducer and the horn. These three quantities have a suitable value for each other. When the energy exceeds the appropriate value, the melting amount of the plastic is large, and the welding material is easily deformed; if the energy is small, the welding is difficult, and the applied pressure cannot be increased. This optimum pressure is the product of the length of the side of the welded portion and the optimum pressure per 1 mm of the edge.        Ultrasonic welding is a high-tech technology for welding thermoplastic technology. Various thermoplastic rubber parts can be processed by ultrasonic welding without adding solvent, adhesive or other auxiliary products. The advantage is to increase productivity and reduce cost. improve product quality.        Ultrasonic plastic welding principle: The generator generates 20KHZ, (or 15KHZ) high-voltage, high-frequency signal, through the conversion system, converts the signal into high-frequency mechanical vibration, which is applied to the workpiece of plastic products, through the working surface and the intrinsic intermolecular The friction causes the temperature to be transmitted to the interface to rise. When the temperature reaches the melting point of the workpiece itself, the workpiece welding port is rapidly melted, and then filled in the gap between the interfaces. When the vibration stops, the workpiece is simultaneously cooled and fixed under a certain pressure. , to achieve the perfect welding.      Ultrasonic spot welding machine can be used for thermoplastics welding by converting 50/60 Hz current to 15, 20, 30, or 40 kHz power through the ultrasonic generator. The converted high-frequency electrical energy is again converted into mechanical motion of the same frequency through the ultrasonic transducer, and the mechanical motion is then transmitted to the welding head through a set of amplitude modulator devices(booster) that can change the amplitude. The vibration energy received by the welding head is transferred to the joint of the workpiece to be welded. In this area, the vibration energy is converted into heat energy by means of friction to melt the plastic. After the vibration stops, the transient pressure maintained on the workpiece causes the two weldments to solidified into one body in the form of molecular linkage. Generally, the welding time is less than 1 second, and the welding strength obtained can be comparable to the body. Features: * Good quality famous brand components are used to realize the strong power and stable performance.* Compact design with small size, saving space.* Low noise, low power consumption, environment friendly* High efficiency with strong welding results. ApparelClothing fabric, underwear spot welding, etc.LabelLogo, woven labels, marks welding or spot welding, etc.Shoe materialTPU vamp positioning spot welding, smoothen shoe head wrinkles, etc.PoultryChicken manure belt, egg conveyor belt welding, etc.AutomobileAutomotive trim wrapping, trim riveting, steering wheel dustproof sleeve welding, etc.ElectronicPlastic parts, rubber column riveting, soundbox covering cloth welding, etc.PackagingPVC spot welding, plastic box sealing welding, etc.Non-wovenFace mask, non-woven bag welding, etc.RibbonRibbon, elastic belt weldingFilter net or bagVelcro welding, film welding, etc.  ItemParameterAdvantage:Application28Khz ultrasonic hand welderStraight type▪ 28Khz 800W▪ Digital generator▪ Horn customized▪ Aluminum alloy&Steel & Titanium alloy▪ Power Supply: 220v 50/60HZ1. light generator ,light hand welder.The generator 120*120*380, whole weight5KG, with generator 4kg, and the 28Khz hand welder 1kg, 35Khz hand welder 0.8kg.
