35kHz High Power Portable Ultrasonic spot Welder 800W Low Energy Consumption

Introduction:
Ultrasonic plastic welding machine is a welding equipment developed in the field of plastic welding, the industry is referred to as the ultrasonic plastic welding machine for short. Ultrasonic welding equipment is a high-tech technology for welding cooked plastic products. All kinds of cooked plastic parts can be treated with ultrasonic welding. When welding plastic products, do not add any adhesives, fillers or solvents, nor consume a large amount of heat .It has the advantages of easy operation, fast welding speed, high welding strength and high production efficiency. Therefore, the ultrasonic welding technology is more and more widely used.

Parameter:

Working principle
When the ultrasonic wave is applied to the thermoplastic plastic contact surface, it will generate tens of thousands of high-frequency vibrations per second. This kind of high-frequency vibration reaches a certain amplitude. The ultrasonic energy is transmitted to the welding zone through the upper welding piece. The welding interface has a large acoustic resistance, so local high temperatures can occur. Also, due to the poor thermal conductivity of plastics, they could not be released in time and gathered in the welding zone, which caused the contact surfaces of the two plastics to melt rapidly, and after a certain pressure was applied, they were merged into one. When the ultrasound stops working, let the pressure last for a few seconds to make it solidify and form, so that a strong molecular chain is formed to achieve the purpose of welding, and the welding strength can be close to the strength of the raw material. The quality of ultrasonic plastic welding depends on the three factors of the transducer welding horn amplitude, the applied pressure and the welding time. The welding time and the welding horn pressure can be adjusted. The amplitude is determined by the transducer and the horn. There is a suitable value for the interaction of these three quantities. When the energy exceeds the suitable value, the melting amount of the plastic is large, and the welded material is easily deformed; if the energy is small, the welding is not easy, and the applied pressure cannot be too large. This optimal pressure is the product of the edge length of the welded part and the optimal pressure per 1mm of the edge.

Advantages:
This switchable ultrasonic spot welding equipment can freely switch between the two holding methods
Pistol type ultrasonic spot welding machine: The shape is designed according to ergonomics. The ultrasonic start switch is located at the trigger of the pistol, which is convenient for lifting and use. It is especially suitable for horizontal or vertical welding operations.
Straight-hold ultrasonic spot welder: The shape is a straight-tube design. The ultrasonic start switch is located on the outside of the straight-tube, which is convenient for hand-held welding and carrying.
