1. Insufficient ultrasonic power
Insufficient ultrasonic generator power is also a factor leading to poor welding. However, considering that many customers will choose cheaper machines to buy machines, the problem of insufficient power is not detected in time. When using the product in the later stage, if the ultrasonic power is not large enough, the welding product range in the welding field will also lead to poor welding. Solution: Try to buy a high-power plastic welding machine to ensure future use.
2. Stress problems
In terms of after-sales service, many ultrasonic welding machine manufacturers have problems due to unstable air pressure in the factory. Gas pressure instability is also an important factor leading to welding failures in ultrasonic welding machines. First, new machines must pass rigorous internal testing before leaving the factory. Make sure there are no problems before normal shipment. However, when the customer uses the machine. All types of welding problems can occur because before purchasing a machine, a sample test of the machine is usually performed to ensure that there are no problems with the machine test before shipment. So, when we contact customers, why does the problem of poor welding occur? After repeated testing and debugging, the ultrasonic generator did not find any problems. Qualsiasi domanda?
After long-term observation, it is found that barometric pressure instability is the cause of barometric pressure instability. Incorrect welding occurs only when the machine is in normal use at the end of the work. This problem recurred during normal business hours. Therefore, we believe that unstable air pressure will affect the normal welding of ultrasonic welding machines. Because many devices that require natural gas work at the same time, the pressure is reduced when the gas is too far away. The solution is to use smaller cylinders instead of larger ones, or add a separate air compressor to supply air to the ultrasonic plastic welder.
3. Plastic materials
There are many plastic materials that can be used with ultrasonic spot welding machines. If other materials are added to the material of the handheld ultrasonic spot welding machine, the welding firmness will also be affected. For example, adding glass fibers to a PC can affect the overall welding firmness. Risolvere. Use a single thermoplastic material. The above is a common welding improper problem of ultrasonic plastic welding machine, but it may also lead to other problems, which are relatively invisible problems, and it is difficult to find without attention.

4. The rack manufacturing is not accurate enough

A portable ultrasonic spot welding machine seems to be a device that has no other difficulties than an ultrasonic system. In fact, this is a false view. Although the ultrasonic generator is the core component of the ultrasonic welding machine, in addition to the ultrasonic generator, there are also problems with the frame of the plastic welding machine. If the frame design is unreasonable and the processing is not accurate, this is likely to occur during use. It directly affects the welding pass rate of the product. If the machine design is not reasonable, it will also affect the welding firmness of the product. In addition, if the processing is inaccurate and rough, the balance position of the mold cannot be found when changing the mold, which may also lead to product welding. The solution is to directly replace the better rack, try to do the procurement work before buying the machine, and learn about the equipment.
