Ultrasonic machining plastics factors as follows: (1) the design of the contact surface (2) the design of the welding wire (3) of plastic material (4) the shape and size of plastic parts (5) the distance between the welding surface and the welding head (6) (7) the amplitude of the welding head of the welding head design (8) the accuracy of the calibration mode (9) pressure welding, ultrasonic welding procedure to select the time parameters: amplitude selection, secondary rod tuning frequency correction mode when the over-melting: Save small welding time, the pressure is not enough to reduce the number of segments amplitude welding: welding time or increased pressure; the number of segments increased amplitude; use higher power models; choose a larger proportion of the secondary rod; determine all the parameters of ultrasound two main parameters: Frequency: F ≥20KHz (in practical applications because the effect is similar to the ultrasonic melt machine, usually F≥15KHz also called ultrasonic sound waves); power density: p = transmitted power (W) / emitter area (cm2), typically p≥0.3w / cm2. An ultrasonic wave propagating in the liquid of dirt can be cleaned surface, the principle can be used "cavitation" phenomena explained: When ultrasonic vibration sound waves propagating in the liquid pressure reaches an atmospheric pressure, the power density of 0.35w / cm2 ultrasonic hot melt machine price, then the ultrasonic sound waves can reach the peak pressure vacuum or negative pressure ultrasonic melt machine products, but in fact the presence of ultrasonic melt machine no negative supply, resulting in a lot of pressure in the liquid, the smashed a hole to pull the liquid molecules cavitation nuclei. This is very close to empty the vacuum pressure in the ultrasonic reverse it reaches the maximum rupture produced a strong impact due to the rupture of the surface of the object hit the dirt down. This shock wave phenomenon by numerous small cavitation bubbles burst produced called "cavitation" phenomenon. Sound intensity is too small can not produce cavitation.
