Basic principle
EPT welding is to change 50 / 60 Hz current into 15, twenty, thirty or forty kHz EPTT by ultrasonic generator. The converted substantial-frequency electric powered energy is converted into the mechanical movement of the exact same frequency again via the transducer, and then the mechanical movement is transmitted to the horn via a set of horn unit which can alter the amplitude. The vibration energy EPTd by the horn is transferred to the joint of the workpiece to be welded. In this area, the vibration power is transformed into heat strength by friction, and the plastic is melted. EPT can be utilised not only to weld hard thermoplastic plastics, but also to procedure materials and movies. Warmth energy will come from the reciprocating motion of a workpiece on an additional floor with a particular displacement or amplitude unEPTTa specific stress. As soon as the expected welding degree is attained, the vibration will end, and at the same time, there will nonetheless be a specific strain used to the two workpieces to amazing and solidify the just welded components, hence forming a near combination.
EPT plastic welding EPTT is broadly utilised in auto industry, digital industry, healthcare business, house EPT business, non-woven apparel, place of work materials, EPTT business, toy industry and so on.For example, vehicle body plastic areas, car doors, auto gauges, automobile lights, mirrors, EPTTshades, interior trim, filters, reflective materials, reflective street nails, bumpers, cable, motorbike plastic filters, warmth dispersors, brake fluid tanks, oil cups, drinking water tanks, gas tanks, air pipes, tail gas purifiers, tray filtersPlastic electronics: Pay as you go h2o meter, electricity meter, interaction gear, cordless telephone, mobile cellphone equipment, mobile phone scenario, battery circumstance, charger, valve controlled seal maintenance direct-acid battery, three-inch fXiHu (West EPT) Dis.Hu (West EPT) Dis.py disk, U disk, SD card, CF card, U SB connector, EPTTtoothToy stationery: folder, album, folding box, PP hollow board, pen established, ink box, toner cartridge,Health-related daily: watches, kitchen utensils and EPTs, oral liquid bottle caps, drip bottle caps, cellular telephone accessories, king gentle brush, day-to-day necessities, health materials, children’s goods, air EPT, hangers, deal with, XiHu (West EPT) Dis.Hu (West EPT) Dis.den supplies, kitchen ware, showers, king gentle brush, shower head, anti-faux bottle, cosmetic bottle, coffee pot, washing EPTTs, air dehumidifier, electric iron, electrical kettle, EPT cleaner, sEPTer wood grille steel area include and soil, etc

EPT dilemma one: abnormal overload of ultrasonic current
When the generator sends out an overload alarm, check out as follows:
1. Often the no-load take a look at is regular, but it can not operate typically. It may possibly be that the internal adjustments of the welding head and other audio strength factors guide to very poor seem vitality EPTT. Right here is a relatively basic judgment technique: hand contact approach. The amplitude of the typical doing work welding head or horn area is quite uniform, and the hand feels smooth like velvet. When the audio strength EPTT is not smooth, there will be bubbles or burr when the seem power EPTT is not easy. At this time, the elimination method need to be employed to get rid of the defective components. When the generator is irregular, the same circumstance can be created, due to the fact generally, the enter waveform of the transducer ought to be smooth sine wave. This phenomenon can also happen when there are spikes or abnormal waveforms on the sine wave. In this scenario, yet another EPTT department acoustic vitality component can be employed to distinguish.
two. EPT no-load test, if the operating current is regular, it might be that the ultrasonic welding head contacts the object that must not be contacted or the parameter adjustment among the ultrasonic welding head and the welding foundation is defective.
3. When the ultrasonic no-load take a look at is irregular, very first notice regardless of whether there are cracks in the ultrasonic mildew and regardless of whether the installation is company. Then take away the welding head and then carry out the no-load examination to excEPTT regardless of whether there is a problem with the ultrasonic transducer ultrasonic horn, and eliminate phase by action. Right after reducing the chance of transducer horn failure, the new welding head shall be replaced to decide.
EPT issue two: irregular heating of ultrasonic mildew
When the ultrasonic mould is doing work, there will be a particular heating phenomenon, which is induced by the mechanical strength reduction of the material itself and the heat conduction of ultrasonic objects. No matter whether the heating of ultrasonic mildew is regular or not is judged as: when the ultrasonic mold is not loaded (i.e. not making contact with the workpiece), the ultrasonic wave is continually emitted for a lot more than half an hour, and the temperature ought to not exceed fifty-70 ordmC. If the warmth is ruined, it is proved that the ultrasonic mold has been ruined or the material is unqualified and demands to be replaced if the mold temperature is as well substantial, it is normally accompanied by irregular substantial ultrasonic recent
EPT difficulty 3: ultrasonic mold howling irregular
When the ultrasonic mold screams, the adhering to causes should be analyzed:
one. Regardless of whether the ultrasonic mildew is in make contact with with the item that ought to not be contacted
two. Whether the screw of ultrasonic welding head is unfastened
three. Whether or not there are cracks in ultrasonic mold
