Mask ear strap ultrasonic spot welding machine
The ultrasonic spot welder for mask ear straps is suitable for applications where the power requirement does not exceed 500 watts. The welding machine can be used with appropriate hand-held equipment, or it can be directly connected to a converter/booster/speaker group for automation. Ultrasonic spot welding machine has the characteristics of fast welding speed, high strength, beautiful welding seam, good sealing, low energy consumption, and simple operation. It is the development direction of welding machine.
When the ultrasonic is applied to the thermoplastic material, it will generate tens of thousands of high-frequency vibrations per second. This high-frequency vibration with a certain amplitude will cause local high temperature. In addition, due to the poor thermal conductivity of the fabric, the temperature cannot be dissipated in time for a while. The welding area causes the contact surface of the two cloths to melt rapidly. After a certain amount of pressure is applied, they merge into one. When the ultrasonic stops, let the pressure continue for a few seconds to solidify and form a solid molecular chain to achieve the purpose of welding, and the strength is close to the strength of the raw material. Ultrasonic single-head spot welding machine is widely used in the top and bottom stop spot welding of zippers, clothing printing, underwear shoulder straps, underwear, bras, non-woven fabric welding, mask ear strap welding.
