The influence of workpiece material on ultrasonic plastic welding machine

At this stage, in the welding of plastic product workpieces, ultrasonic plastic welding machines are playing a key role, but different plastic materials will have a certain impact on the actual operation and effect of welding of machinery and equipment. Product workpiece materials have a certain impact on ultrasonic plastic welding machines. What is the impact?

1. The impact of recycled plastics:

There are many types of plastics, but among them, the compressive strength of recycled plastics is relatively poor, so its ability to adapt to ultrasonic welding is relatively poor. If ultrasonic welding must be carried out on recycled plastics, the specifications of various design schemes of materials are equal. There are many considerations to consider as appropriate.

2. The influence of the disadvantages of environmental humidity:

There are certain differences in the environmental humidity of different plastic materials. The disadvantages of environmental humidity are generally caused in the process of making gray spots or loose plastic parts. The disadvantages of environmental humidity are attenuated by the effective kinetic energy during welding, which causes leakage and prolonged sealing. Welding time, so plastic parts with high environmental humidity should be air-dried before welding with ultrasonic plastic welding machine.

3. The influence of release agent and residue:

The release agent and residue in the plastic product workpiece have a certain effect on ultrasonic welding. Although the organic solvent and residue on the surface of the production and processing can be shaken off during the ultrasonic production and processing, it is aimed at the specified tightness or high toughness. It should be removed as much as possible under the condition of, generally the plastic parts will be cleaned before applying the ultrasonic plastic welding machine.

4. The impact of shelf life:

After the plastic product is processed by the injection mold, it must be placed for at least 24 hours before welding to solve the stress, deformation and other factors of the plastic part. Otherwise, it will affect the welding effect of the ultrasonic plastic welding machine. Plastic parts processed by injection molding do not follow this rule.
