Professional Ultrasonic Plastic Welder Manufacturer
Choosing the Right Ultrasonic Welder for Plastics
At Hyusonic, we offer a range of ultrasonic plastic welders tailored to different levels of performance, precision, and ease of operation. Our main recommended series include the ST Series, X Series, and iQ Series, each designed to meet specific application requirements.
The higher your requirements for welding strength, precision, airtightness, or compliance standards (e.g., for medical or food-grade packaging), the more advanced the system configuration you will need.
For manufacturers who only need basic weld feasibility to improve process stability and boost productivity, we also offer the entry-level S Series—a widely used standard model in the market, highly affordable and practical for general production upgrades.
In short:
Basic Feasibility (S Series): Ideal for general production upgrades. Relies on straightforward Time/Pressure trigger modes for highly affordable, high-volume standard part assembly.
Process Stability (ST Series): Engineered for parts requiring tighter tolerances. Features Energy Mode and variable amplitude control to compensate for slight material inconsistencies.
Advanced Traceability & Precision (X or iQ Series): For medical or automotive lines demanding zero-defect data. Features 0.5ms closed-loop data acquisition, Collapse Distance control, and MES/Industry 4.0 integration capabilities.
How Ultrasonic Plastic Welding Works
Ultrasonic plastic welding uses high-frequency vibrations to create localized heat between thermoplastic materials. The pressure applied during welding ensures a solid, clean, and consistent joint without adhesives or solvents. It’s ideal for automotive, medical, and electronics industries.
What is the price of an ultrasonic plastic welder?
Our ultrasonic plastic welders range from $2,000 to $50,000, depending on configuration, components, and system design. Low-end machines resold by traders often lack support and stability. Choose manufacturers with proven technical strength and reliable service—not just the lowest price.
Is there a warranty and after-sales service?
Yes, all our ultrasonic plastic welders come with a standard 12-month warranty. We provide full after-sales support, including technical guidance, spare parts, and remote troubleshooting to ensure stable, long-term operation.

Customer FAQs
How does ultrasonic plastic welding work?
Ultrasonic welding uses high-frequency vibrations (15-40kHz) to generate friction heat between thermoplastics, melting materials under pressure to form a molecular bond—no adhesives or external heat required. Key components: generator, transducer, and horn.
What plastics can be welded ultrasonically?
Can ultrasonic welding achieve a hermetic seal?
Yes. By optimizing the Energy Director geometry and using Collapse Distance mode, our systems ensure consistent, leak-proof hermetic seals required for fluid paths and sensor housings.
Can ultrasonic welding join dissimilar plastics?
A compatibility chart is available for download only if they share similar melting points (e.g., ABS to PC).
What’s the lifespan of a titanium horn?
Titanium horns last 2-5 years with proper maintenance. Check for cracks or frequency drift annually.
