Q: What are the main factors affecting the energy of ultrasonic plastic welding?
A: Air pressure: We can adjust it through a pressure regulating valve. Generally speaking, the greater the air pressure, the greater the energy; the descending speed: there are corresponding knobs on the ultrasonic welding machine. Generally speaking, the greater the descending speed, the greater the energy; frequency: Ultrasonic welding machines have a fixed frequency. The higher the frequency, the greater the energy. Amplitude: There are more changes in the amplitude. Generally speaking, the adjustment of the amplitude can be achieved by the design of the amplitude modulator and the welding head; time: we can Adjust the welding time of the ultrasonic welding machine, the longer the time, the greater the welding energy; Holding pressure time: Holding pressure time is the time to maintain the air pressure after the plastic is melted. The longer the time, the more stable the formed solder joints and the smaller the deformation.
Q: What aspects of the welding workpiece should be considered when choosing an amplitude modulator?
A: The welding area-the larger the area, the higher the amplitude required; the workpiece material-PP/PE/nylon and other hard-to-weld crystal resins, the higher the amplitude is required; the structure of the workpiece- - If the workpiece has slender pillars or thin slices that are easy to crack, a weaker amplitude should be used.
Q: What impact will the pressure be too low or too high on the welding workpiece?
A: If the pressure is too low, the welding time will be prolonged, and the surface of the workpiece will be scarred or the quality will be poor; if the pressure is too high, the workpiece will be broken, the interface will be poorly bonded, or even overload, and the ultrasound will be terminated.
Q: What are the disadvantages of too long welding time?
A: Too long welding time will cause flashing or quality degradation, especially in the case of strict sealing, pay more attention; too long welding time will cause the workpiece to deviate from the welding zone, the surface will melt or crack, especially if there are holes Position, mold line or head corner. Note: The general welding time is 0.3S~0.5S. When there is an elastic device, the material has a high melting point or the material is elastic, the pressure holding time must be increased. Such as: PP/PE, etc.
Q: What are the advantages of designing fuses and common structural designs?
A: The main advantages of fusible wires are: increase welding strength, reduce glue overflow, reduce welding time, and require smaller amplitude; common structural designs of fusible wires are: stepped fusible wires, grooved fusible wires, Cross-type fuses, vertical wall fuses, discontinuous fuses, chisel fuses, biting fuses, and waterproof fuses.
Q: What are the advantages of shear welding surfaces?
A: The advantages of shear welding: high welding strength and good air tightness; suitable for all plastic materials, especially semi-crystalline plastics with early solid characteristics.
Q: What are the disadvantages of the shear welding surface?
A: It is not suitable for structures with complex shapes or right-angle corners. Welding requires solid side wall support, otherwise it will be deformed and require larger amplitude and power. It is only suitable for smaller workpieces.
