Ultrasonic plastic welding machine which is used in many fields, ultrasonic spray nozzle in mobile phones, chargers, U disk, SD card and adapter, and other products, and in the medical industry and electronic industry also have them. Plastic welding is a technical business, in the welding process, will encounter all sorts of problems, the most common are welding repair, what should we adjust, here are a few tips, want to tell you!
1, check the machine
Before plug-in power, carefully check the integrity of the equipment parts and strong degree, whether the base of the screw fastening machine, machine panel screws are loose, electricity box of electrical components in the process of transportation whether there are any loss.
2, install mold
Installation of correspondence plastic mould and parts, when ultrasonic handheld welder installation according to the welding requirements of plastic parts for installation, installation debugging moulds for the next step to leave certain adjustment space, such as mold fastening screws, tracheal joints, etc. In the process of the installation, pay attention to the mould installation must be debugging welding to prepare for later.
3, power supply, air supply is connected
Joint equipment of power supply, in this process, pay attention to the wiring correctness of equipment power supply when the power supply is connected to pay close attention to electrical box, if discovery is unusual, rapidly shut off the main power supply, check the electrical components, or get in touch with equipment manufacturers, turn on the air, the factory must have a pump or air source for equipment use, and then select the suitable trachea, connect the pump and equipment, when air supply is connected, check whether the barometer is normal, and then check if the cylinder to the corresponding position, if discovery is unusual, please contact with equipment manufacturers, in the related technical personnel under the guidance of debugging
4, mechanical debugging
Before starting operation, equipment level of mesa to first, Ultrasonic nano dispersion open source, start equipment start switch, push the power switch, the boot device in manual state, the pressure value of equipment, cylinder stroke speed, set the height of the upper die down, adjust the limit screw. In the condition of automatic test run, and then let the equipment immediately stop or stop button, shut down equipment, check the exception
Because in different condition, the ultrasonic welding instantaneous temperature vary widely. With 1500 w20hkz ultrasonic machine, when welding the 1 s, pressure is 5.5 KgF \ in different welding (welding of soft and hard) of the material when the temperature vary hundreds of degrees Celsius. If the pressure and welding are not with the words of the phase difference.
