Sonic Welding Plastics Case
Generally, the material of the automotive dashboard is PP, PC, ABS, PVC, etc., which can be welded by ultrasonic plastic welding equipment, by assembling the corresponding welding sonotrode to achieve perfect welding. The joining seams are precise and not overflowing, and welded dashboard is firm and beautiful.
The filter material is generally PP, PA, and PVC. When processing filters, it is necessary to ensure good air and water tightness. Selecting ultrasonic bonding air filter accessories can meet this requirement with high precision size and the appearance will not be scratched.
The common material of the medical infusion bag is PP or TPE.Use ultrasonic to weld the medical infusion bag tightly, significantly reduce the volume of the sealing area, and ensure there is no air in the bag. With short welding time, repeatable effect, and high reliability.
The common material of the Bluetooth headset is ABS or PC, the welding of the Bluetooth headset not only requires the welding seal to be free of spillage and has a beautiful appearance, but also to ensure that the internal electronic equipment will not be damaged due to welding. Ultrasonic welding can meet the above requirements.
Home appliances that are closely related to our lives, such as electric irons, must be strong and durable. The common shell material of the electric irons is ABS and PP.

Ultrasonic Plastic Welder Selection Guide
Before choosing ultrasonic welding for your plastic products, read the guide below; Here is a list that covers the frequently asked questions.
Ultrasonic plastic welders have many advantages in the manufacturing and assembly of plastic components and are now acceptable in many industries. The common advantages are listed below:
1. Fast and Efficient:
Ultrasonic welding plastic can be done within 1 second or even less, which is fast and greatly improves the industry production efficiency.
2. No Consumables:
No like other traditional welding methods, ultrasonic welding technology needs no consumables, such as glues, screws, and other additional materials.
Ultrasonic welding technology uses focused ultrasonic vibration to generate heat only in the area that needs to be welded, which results in less energy consumption compared to other common heating methods.
4. Clean and Consistent:
Ultrasonic welding can ensure the cleanness of the product surface without additional solvents or adhesives, this is very suitable in some application fields that have strict welding requirements, such as the medical industry.
5. Reduced Material Distortion:
Because of the locally focused heat generated by the ultrasonic vibration of the ultrasonic welding technology, it minimizes the overall thermal impact on the surrounding material, which results in reduced material distortion or damage.
Ultrasonic welding can be used for a wide range of thermoplastic materials, including hard-to-weld materials such as certain engineering plastics. It makes ultrasonic welding a preferred choice in various industries, including automotive, electronics, and medical devices.
7. Automation Compatibility:
Ultrasonic welding is adaptable to automation systems, which enhances precision, consistency, and overall production efficiency.
8. Environmentally Friendly:
Ultrasonic welding doesn’t involve the use of potentially harmful substances.
9. Joining Complex Geometries:
Ultrasonic welding is capable of joining parts with complex geometries and intricate designs, providing flexibility in the design and manufacturing of plastic components.
While ultrasonic plastic welding offers the advantages above, it’s essential to consider specific application requirements and material compatibility to determine the most suitable joining method for a given project. If you have plastic joining requirements, please first contact our professional team for expert suggestions.
Sure. Thermoplastics can be well welded by ultrasound. Common plastic types that can be welded by ultrasonic are acrylonitrile butadiene styrene(ABS), polystyrene(PS), polyvinyl chloride(PVC), polyphenylene oxide(PPO), Polypropylene(PP), Polyethylene(PE), Polycarbonate(PC), Pci Universal Communications(PUC), poly(methylmethacrylate(PMMA), Polyphenylene Sulfide(PPS), polybutylene terephthalate(PBT), Polyethylene terephthalate glycol(PETG), Polyamide(PA), Polyvinyl Chloride(PVC), etc.
Ultrasonic welding is a welding method that uses ultrasonic technology to weld plastics, metals, and other materials. Robotic welding is an automated welding process that combines welding, robotics, sensor technology, control systems, and artificial intelligence. As technology continues to advance, ultrasonic bonding and automation can be combined to meet higher quality, productivity, and cost reduction requirements.
Plastic product welding requires water tightness or airtightness in some industries. Before choosing ultrasonic welding machines, consider the plastic product itself first:
1. Determine whether the material of the plastic product can be ultrasonically welded;
2. Whether the wall thickness structure of the upper and lower parts of the plastic product is suitable for the positioning of the energy conductor;
3. Whether the structure of the product to be welded is a flat structure or a concave-convex structure;
Any questions, you can consult our professional team to help you. Just Feel free to contact us.
Ultrasonic bonding takes a short time so that the plastic products are instantly melted and fused together, the welding is firm, and the welding strength can be close to the raw materials.
When choosing ultrasonic joining for the joining of electronic product shells, requires the internal electronic components not to be damaged. Select a higher frequency ultrasonic welding machine, and precisely design and process the corresponding welding heads and fixtures to meet the needs.
