Fusing and fracture are also possible that in the part portion far from joint area when longer weld interval, the hole especially in moulded parts
Hole, welding line and sharp corner are in this way.
Amplitude is the important parameter that a control thermoplastic squeezes flow rate.In ultrasonic welding process, if
Amplitude is too small, and welding energy is inadequate, and the place weldering of the weldering is loosely.If amplitude is too big, weldering, gummosis or burn-through were caused.Gao Zhen
When width, weld interface heating speed is higher, and temperature rises, and molten material flows fast speed, and molecularly oriented is caused to increase, and generates
A large amount of overlaps and weld strength are lower.High amplitude is required for starting fusing.Too low amplitude generates non-uniform beginning
Fusing and the solidification of premature melt.When increasing amplitude, a greater amount of vibrational energies consumes the part to be welded in thermoplastic
Bear bigger stress.During entire weld cycle when amplitude constant, what is generallyd use is to be unlikely to generate to part to be welded
The crest amplitude excessively damaged.For crystalline plastic such as polyethylene and polypropylene, the influence of amplitude is such as than amorphism plastics
ABS and polystyrene are much greater.This may be since the fusing and welding of crystalline plastic need more energy.
Moisture content in material influences weld strength.Hygroscopic material such as polyester, polycarbonate, especially nylon are from air
Middle absorption moisture.The moisture absorbed when welding can boil at 100 DEG C, survival gas can generate stomata and the faying face that may degrade at
Plastics, cause appearance to be deteriorated, in conjunction with bad and be difficult to obtain hermetic seal.To obtain optimum efficiency, these materials Ying Mo
It is welded immediately after system.Available dedicated oven drying part before welding, but must be noted that avoid material degradation.
