What Is Ultrasonic Welding?

Ultrasonic welding is a high-tech process that can be applied to all thermoplastic products. The transducer converts high-frequency and high-voltage signals into high-frequency mechanical vibrations, which are applied to the plastic products, causing rapid friction between the two parts of the products so that the temperature rises. When the temperature reaches the melting point of the product itself, the interface of the product melts rapidly. At the same time, it is cooled and formed under a certain pressure to complete the welding.

When choosing the material for ultrasonic welding molds, the material of the ultrasonic welding head is generally magnesium, steel, titanium alloy, 7075 aluminum alloy, 6061 common aluminum material, etc. Among them, 7075 aluminum alloy is outstanding, as it has high hardness, strong heat conductivity and good toughness, making it very suitable for the material of ultrasonic welding heads. However, the main choice still depends on product requirements.

Why Choose Ultrasonic Products?

Ultrasonic welding is a good process with a fast, clean and effective assembly. It is used to meet the high-strength assembly requirements of plastic parts and is a widely used advanced assembly technology, applicable to the assembly of various types of plastic parts.

Also,when you need to get a product with better sealing or apperance,then the Ultrasonic welding is the best choice.

Advantages:
Environmental protection and energy conservation:,and no need to add auxiliary materials, reducing production costs.
Improve quality of product,and enhance the strength and durability of plastic parts.

How Decide To Choose Ultrasonic welding?

Firstly, some plastics material with lower melting points need to be used, and the design of the weld lines for the products and their components should be carefully considered.
Secondly, when choosing plastics material, their properties should be taken into account, whether they are amorphous or crystalline. Whether the welding effect is stable and reliable, and whether the plastic material can be reused, the selection of appropriate plastics material and good design cannot be ignored. The molded plastics material must have excellent stability and should not have problems such as deformation, bubbles or shrinkage.

What Plastic Materials Are Suitable For Ultrasonic Welding?

Ultrasonic welding is suitable for all thermoplastic materials, including non-crystalline plastics such as ABS, PMMA, PC, PS; semi-crystalline plastics such as PA, PET, CA, POM, PE and PP.
