Several factors affecting ultrasonic welding
1. Release agent and impurities: Release agent and impurities have a certain influence on ultrasonic welding. Although the solvent and impurities on the processed surface can be shaken away during ultrasonic processing, it should be removed as much as possible when sealing or high strength is required. In some cases, it is necessary to clean the plastic parts first.
2. Design of plastic parts: modern injection molding methods can effectively provide perfect welded plastic parts. When we decide to use ultrasonic welding technology to complete the fusion, the structural design of plastic parts must first consider the following points:
1. The size of the weld (it is necessary to consider the required strength)
2. Whether it needs to be watertight or airtight
3. Do you need a perfect appearance
4. Avoid plastic melting or overflow of synthetics
5. Whether it is suitable for welding head processing requirements
Several factors affecting ultrasonic welding:
3. Recycled plastics: The strength of recycled plastics is relatively poor, and the adaptability to ultrasonic welding is also poor. Therefore, if recycled plastics are used, various design sizes should be considered as appropriate.
