Application: Plastic, electronics, electrical appliances, auto parts, packaging

Welding soundproof cotton on the engine cover can effectively reduce mechanical noise, combustion noise, and aerodynamic noise, and the soundproof cotton also has good heat insulation effect, which can effectively prevent the high temperature of the engine from being directly transmitted to the engine cover, thereby protecting the surface of the engine cover Car paint, while avoiding the fog of the hood and affecting the sight in rainy weather. The traditional process adopts manual adhesive bonding, not only the production efficiency is slow, but the adhesive is easy to cause pollution, and the adhesive is easy to fail under high temperature conditions, causing the sound insulation cotton to fall off. The hand-held ultrasonic welding machine can realize the welding of sound insulation cotton and engine cover.

Working principle of 35K Spot Welding Machine

The principle of the Hand-Held Ultrasonic Spot Welding Machine is to use an ultrasonic generator to convert ordinary current into high-frequency electrical energy, and then convert it into mechanical motion of the same frequency through a transducer. The mechanical motion is transmitted to the welding head through the horn device. The generated vibration energy is transferred to the part to be welded. The thermal conductivity of the thermoplastic material is relatively poor. The local high temperature generated by the vibration energy in the welding zone melts the thermoplastic material. With a certain pressure, the two parts to be welded are fixed and bonded together. The designed handheld spot welding machine uses ultrasonic welding technology to realize the welding of the engine cover and the sound insulation cotton.

The engine cover is a thermoplastic material, and the sound insulation cotton is polyester fiber cotton. It has been verified that the two can be welded by plastic ultrasonic technology. When the ultrasonic equipment is working, specific parts of the engine cover are melted by each welding head and produced by the cylinder. The pressure welded the sound insulation cotton and the melting part of the engine cover together, blowing air to cool, and the welding part solidified, in this way, the welding of the two is realized.

The use of plastic ultrasonic technology to weld the automobile engine cover and the sound insulation cotton together has changed the disadvantages of manual welding or bonding in the past, realized the automation of production, and was environmentally friendly. With the development of plastic ultrasonic technology, its application range will be further expanded with its high efficiency production efficiency and reliable quality assurance.
