Ultrasonic plastic welding machine prices start at roughly $700 to $2,000 for low-power handheld or small bench units and rise to several thousand dollars for mid-power machines. Branded industrial systems with automation are usually sold by quote, and prices depend on power, frequency, controls and tooling. These are rough market ranges, not manufacturer list prices, so always get a written quote that includes tooling.
About these prices: This guide gives rough price ranges from marketplace listings and supplier pages. Manufacturers such as Branson, Herrmann and Dukane generally do not publish list prices, so treat every figure here as an estimate.
Quick Answer
Expect about $700 to $2,000 for low-power entry-level units, about $2,000 to $6,000 for mid-power machines (600 to 2,000 watts), and $6,000 or more for high-power or automated systems. Horns, fixtures and installation are often extra.
Key Takeaways
- Power (watts), frequency (kHz) and controls are the biggest price drivers.
- The horn (sonotrode) and fixture are made for your part, so budget for tooling on top of the generator.
- Ultrasonic welding is designed for thermoplastics; it does not replace TIG or MIG on structural metal.
- Industrial brands are mostly quote-only, so compare written quotes line by line.
- Entry-level units suit prototypes and light repair; production lines need repeatable, monitored equipment.
Ultrasonic Plastic Welding Machine Price by Tier
| Tier | Typical price (estimate) | Typical use | What to check |
|---|---|---|---|
| Entry-level handheld or small bench unit | About $700 to $2,000 | Prototypes, light repair, hobby and small-batch work | Frequency, power rating, warranty length and seller support |
| Mid-range (600 to 2,000 W) | About $2,000 to $6,000 | Small production runs, electronics and consumer parts | Digital controls, weld time and energy settings, horn options |
| High-power or automated (over 2,000 W) | $6,000 and up; industrial systems often quote-only | Automotive, medical and high-volume assembly | Process monitoring, repeatability, service network, validation support |
The power bands follow price ranges quoted by a machine supplier’s pricing guide (low power 200 to 600 W about $800 to $2,000; medium 600 to 2,000 W about $2,000 to $6,000; high power over 2,000 W about $6,000 and up). Branded industrial systems can cost more than these ranges, and used equipment may cost less.
What Drives Ultrasonic Plastic Welder Prices
- Power output: Higher wattage handles larger or tougher parts and costs more.
- Frequency: Common industrial frequencies run from about 15 to 40 kHz. Lower frequencies suit larger parts, and higher frequencies suit small, delicate parts. The right frequency depends on your part.
- Controls and monitoring: Programmable timing, energy control and data logging add cost but improve repeatability.
- Tooling: The horn and fixture are shaped for your part geometry and material, and each new part may need new tooling.
- Automation: Press frames, feeders, robots and safety guarding add to a production cell price.
- Brand and support: Service networks, training and parts availability are part of what you pay for.
Entry-Level Ultrasonic Welding Machines
Entry-level machines are usually handheld spot welders or small bench units. They suit prototypes, light repairs and occasional spot welding, riveting or sealing of thermoplastic parts. Many low-cost units are sold by importers or marketplace sellers, so check the actual rated power, warranty terms and whether replacement horns are available before you buy.
Mid-Range Ultrasonic Welders: Features and Costs
Mid-range machines add more power and better process control, which helps when you run repeat batches. Look for adjustable weld time, amplitude or energy settings, a stable generator and a choice of horns. Used Branson and Dukane equipment is sold through dealers, but the price depends heavily on age, condition and whether horns and fixtures are included.
High-End and Industrial Ultrasonic Welding Equipment
Industrial systems from makers such as Herrmann and Branson are built for tight process control, monitoring and long duty cycles. Prices are normally quoted for your application and can include the press, generator, converter, booster, horn, fixture and commissioning. Ask each supplier what is and is not included.
Custom Ultrasonic Welding Solutions
A custom setup is designed around your part, material and cycle time. Costs rise with part complexity, tolerance requirements, material type and thickness, and any need for automation or validation. Ask for a trial run on your own parts before you commit, and confirm return and warranty terms in writing.
What Else to Budget For
- Spare horns and boosters, which wear and may need replacing
- Fixtures or nests that hold the part
- Hearing protection and guarding, because ultrasonic welding can be noisy
- Training and trial parts
- Installation, compressed air or electrical supply, and service contracts
Warning: Follow the manufacturer’s safety instructions. Keep hands clear of the horn and fixture area, use guarding and two-hand or light-curtain controls on press systems, and wear hearing protection where noise requires it.
Alternatives to Ultrasonic Plastic Welding
- Hot plate or vibration welding: better for large parts, but the machines are bulky.
- Laser welding: precise and clean, but equipment is usually costlier. See our laser welding cost guide.
- Adhesives or solvent bonding: low equipment cost, but longer cure times and less repeatable results.
- Hot-air or extrusion plastic welding: common for repairs and fabrication. See plastic welding costs.

Frequently Asked Questions
How much does an ultrasonic plastic welding machine cost?
Roughly $700 to $2,000 for low-power entry-level units, about $2,000 to $6,000 for mid-power machines, and $6,000 or more for high-power or automated systems. Industrial brands usually quote by application, so these are estimates only.
Can ultrasonic welders be used for metal welding?
Ultrasonic plastic welders are built for thermoplastics and are not a substitute for TIG or MIG on structural metal. Ultrasonic metal welding is a separate process that uses different machines, mainly for thin foils, wires and tabs.
What is the horn and why does it cost extra?
The horn (sonotrode) transfers vibration to the part. It is shaped for a specific part and material, so each new part may need a new horn, and horns can wear.
Is a used ultrasonic welder worth buying?
It can save money, but check that the generator, converter and horn work together, that parts are still available, and that you can test it on your parts before paying.
What safety features should I look for?
Look for guarding, emergency stop, two-hand or light-curtain controls on press systems, and clear operating instructions. Provide hearing protection where noise requires it and train every operator.
Conclusion
Ultrasonic plastic welding machine prices range from under $2,000 for simple handheld units to quote-only industrial systems. Match power and frequency to your part, budget for the horn and fixture, and request itemised written quotes. Test on your own parts before you buy.
