The output power of the ultrasonic plastic welding machine is determined by the diameter and thickness of the piezoelectric ceramic parts, the material and the craft height. Once the ultrasonic transducer is shaped, the maximum power is also determined. The measurement of output energy is a complex overproduction. The larger the ultrasonic transducer

The greater the output power of the circuit and the use of ultrasonic power tubes, the more appropriate and complex amplitude measuring instruments are needed to accurately measure its amplitude.

     Get rid of the misunderstanding of the ultrasonic welding machine

     How much output power is used? The vibration frequency and amplitude scale are based on the material of the workpiece, the area of the welding wire, whether there are electronic components in the workpiece, whether it can be airtight, etc. I mistakenly believe that the greater the power, the better. This is also a misunderstanding. If you are not familiar with ultrasound. Then consult the engineers and technicians of the regular ultrasonic production factory. If you have the conditions, you can go to the factory to communicate with you. Don't blindly follow the misleading of some non-orthogonal ultrasonic equipment sales staff.

     Strictly check the structural requirements of the ultrasonic welding head

     Conventional ultrasonic mold manufacturers have strict inspection procedures, and process and verify the processing ratio through computer software. In addition to the welding equipment and the technical level of the operators, various factors inside and outside the plastic have a certain influence on the welding quality and should be paid attention to.

     Ultrasonic pressure

     Appropriate pressure is applied to the welding surface, and the welding material will transition from elastic material to plastic. It also promotes the mutual diffusion of molecules and squeezes out the residual air in the weld, thereby improving the sealing performance of the welded plastic surface.

     Ultrasonic welding surface cleaning

     The ultrasonic welding of the plastic surface must be clean and free of impurities to ensure sufficient welding strength and air tightness. In addition to selecting the correct weldable material and eliminating the unfavorable factors that affect the welding effect, a suitable welding method should also be adopted according to the type of material, product shape and cost. According to... different heating and softening methods, plastic welding methods can be divided into external heating source softening, mechanical motion softening, electromagnetic seeding and softening.

     Ultrasonic plastic packing

     Such as glass fiber, talc, mica, etc., they change the physical properties of the material. The content of the filler in the plastic has a great relationship with the weldability and quality of the welded plastic. Plastics with a filler content of less than 20% can be welded normally without special treatment. When the content of the filler exceeds 30%, the insufficient proportion of surface plastic is insufficient, and the intermolecular fusion is insufficient, which reduces the sealing performance.

     Hygroscopicity of ultrasonic plastic

     Ultrasonic welding If wet plastic products are welded, the water contained in the water will be converted into steam after heating, and bubbles will appear on the welding surface, which will weaken the sealing performance of the welding surface. The most hygroscopic materials are PA, ABS, PMMA, etc. Products made of these materials must be dried before welding. ...In addition to the welding equipment and the technical level of the operators, various factors inside and outside the plastic have a certain influence on the welding quality, which should be paid attention to.
