Many ultrasonic welding machine manufacturers are disturbed by the unstable pressure in the factory floor of the user after the equipment is sold, which leads to the problem of weak welding. If the air pressure is unstable, this is the main factor that causes the ultrasonic welding to be unstable. The new equipment will undergo rigorous internal testing before it leaves the factory, and will be shipped only when there are no problems. However, as soon as the machine is transported to the customer, the ultrasonic welding machine will appear to be weak when it is used. This is why the welding is not strong when the customer arrives. The ultrasonic generator has also been repeatedly tested in some parts. After debugging, nothing was found. Do you know where the problem is?

       The rack is not made fine enough

       The ultrasonic welding machine seems to be a device with no difficulty except the ultrasonic system. In fact, this is a wrong concept. Although the ultrasonic generator is the central part of the ultrasonic welding machine, in addition to the generator part, there is also the plastic welding machine frame. If the design of the ultrasonic frame is not reasonable enough and the processing is not fine enough, it is likely to directly affect the welding pass rate of your product during use. If the machine design is unreasonable, it will also affect the product if it causes the machine to fall back. Welding fastness, and if the processing is not fine and rough, it is basically impossible to find a good balanced position of the mold when changing the mold, so it may also cause the welding product to be unable to weld. The solution is to directly change to a better rack, try to do a good job in the purchase before purchasing the machine, and understand the relevant information of the equipment.

       The problem of plastic material itself

       There are many plastic materials that can be welded by ultrasonic. If other materials are added to the material that can be welded by ultrasonic welding machine, it will also affect the welding fastness. For example, the addition of glass fiber to PC will affect the entire welding fastness. The treatment method is to use a single thermoplastic material.

       Insufficient generator power

       Insufficient power of the ultrasonic generator is also a factor that leads to weak welding. I think that many factories will choose cheap machines when purchasing machines, but the negligence is the processing and application of other products in the later stage of the machine. The ultrasonic power is not large enough and the area of welding products exceeds If the welding range is exceeded, the welding will be weak. As a solution, try to purchase a plastic welding machine with high power to ensure subsequent use.
