35k Portable Spot Welding Machine For Soundproof Cotton 

Model：DZ-3509DB Ultrasonic spot welding machine Price:$500-$700 Frequency:35KHZ Power:600W/700W/800W/900W 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…
