2600w High Power 15Khz Ultrasonic Plastik Welding Machine with Duration Control System
Description:
With the rapid development of industrial production, plastics are widely used in various fields of national economy and people's life because of their light weight, high specific strength, corrosion resistance and easy processing. However, due to processing techniques and the like, many complicated products cannot be formed at one time, and it is necessary to seamlessly connect a plurality of components together, and there are basically two methods: bonding and welding. Generally speaking, the bonding process has low production efficiency and the adhesive has certain toxicity, which is easy to cause environmental pollution and harmful consequences for the health of the production personnel. Therefore, the plastic welding process of ultrasonic plastic welding machine has been more and more widely used.

Effect of plastic parts on ultrasonic welding:
1. Ultrasonic waves propagate in plastic parts. Plastic parts absorb or attenuate ultrasonic energy more or less, which has certain influence on ultrasonic processing. Plastics generally have amorphous materials, and hard rubber and soft rubber according to hardness. The distinction between the modulus and the modulus is, in general, the high-hardness, low-melting plastic ultrasonic processing performance is superior to the low-hardness, high-melting plastic. Therefore, this involves the near-far problem of ultrasonic machining distance.
2. The influence of the processing conditions of plastic parts on ultrasonic welding, the different processing forms of plastic parts through injection molding, extrusion or blow molding, and different processing conditions will form factors that have certain influence on ultrasonic welding.
A. Humidity defects: Humidity defects are generally formed during the process of making streaks or loose plastic parts. Humidity defects attenuate energy during welding, so that the sealing position seeps and lengthens the welding time. Therefore, the plastic parts with high humidity should be made before welding. Drying treatment. Such as polyoxymethylene.
B. Influence of the injection molding process: The adjustment of the parameters of the injection molding process will lead to the following defects: a dimensional change (shrinkage, bending deformation) 2 weight change, three surface damage, four uniformity
C. Storage period: After the plastic parts are injection-molded, they are generally placed for at least 24 hours, and then welded to eliminate the stress and deformation of the plastic parts. Plastic parts that are molded from amorphous plastics may not meet this requirement.
D. 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 dimensions should be considered as appropriate.
E. Release agent and impurities: Release agents and impurities have a certain influence on ultrasonic welding. Although ultrasonic waves can shake off solvents, impurities, etc. on the machined surface, they should be removed as much as possible for sealing or high strength. In some cases, it is necessary to clean the plastic parts first.
