Sometimes the ultrasonic spot welding machine will not meet the standard when welding the product, and the water tightness and air tightness test will not meet the standard. The reason is that we are bent on the efficiency and speed of welding products, ignoring some problems:
1. The Ultrasonic Plastic Spot Welding Machine drops too fast.
Dynamic pressure and gravity acceleration will make the ultrasonic guide fuse flattened, so that the fuse can not play the role of the fuse, thus forming a pseudo-phase fuse.
2. The product welding time is too long
Plastic products due to the heating time is too long, not only the plastic material condensation, and then the formation of plastic tissue coking phenomenon, sand eye, water or gas is soaked by sand eye, thus constituting a phenomenon of water tightness and air tightness is not up to standard.
3. Plastic material problems:
Some plastics are easy to ultrasonic welding, and some materials have poor ultrasonic welding performance. Plastic materials are also an important factor affecting the effect of ultrasonic welding.
4. Frequency and amplitude problems of handheld ultrasonic spot welding machine:
The ultrasonic frequency and amplitude required by the structure of different products are different, according to the ultrasonic performance of the material, the wall thickness of the product, determine what power, amplitude and frequency of ultrasonic welding equipment are used; for example: small precision products suitable for high-frequency ultrasonic welding, large volume, ultrasonic line thickness structure requires high-power ultrasonic equipment;
5. Ultrasonic welded structure
Ultrasonic welding wiring structure is diverse, according to the specific situation of the product to design waterproof ultrasonic welding structure, according to the specific product volume, structure, wall thickness and other comprehensive consideration;
In short: when we weld plastic products, such as welding effect is not up to standard, on the one hand, we can find the reason from the Ultrasonic Plastic Welding Machine itself, through the parameters of the ultrasonic plastic welding machine and adjust the ultrasonic mold to achieve the purpose of welding, on the other hand, we can analyze from the aspects of product materials, product structure, product welding wire, etc
