Typical Applications

This electrical-servo ultrasonic welder is used for thin-wall, cosmetic, and high-consistency assemblies, 

especially when force and position must be tightly controlled.Typical uses:

• ESL / wearable & consumer electronics housings

• Medical disposables requiring repeatable sealing

• Multi-layer parts sensitive to whitening or deformation

• Precision joints demanding micron-level collapse control

How to choose Servo vs Pneumatic ?

Choose Servo When:

   • Wall thickness < 1.0 mm or high-gloss surface

   • Leak-rate / pull strength must be CpK-controlled

   • Part-to-part variation is large

Choose Pneumatic When:

   • Thick wall, structural welds

   • Cosmetics are not critical

   • Budget-priority projects

Why Choose Servo vs Pneumatic

• Closed-loop force/position control (0.03 mm accuracy) ensures repeatable welds across part-to-part variation. 

• Programmable motion profiles reduce flash, whitening, and over-travel on thin walls.

• Supports multiple welding modes (time, energy, power, absolute/relative depth) for robust process windows. 

Case Snapshot: medical guide tube

Problem: [flash/whitening/leak-rate scatter/low yield]

Result after TEC servo process: Yield from [75.6]% → [98.8]%, leak-rate CpK [1.33] → [1.73], cycle time 1.5s.

Servo profile control has helped customers achieve higher cosmetic yield and tighter leak-rate 

consistency on  the medical parts.

FAQ

Q1. Can you test my part before purchase?
Yes. Send samples/drawings and we provide a free weld report in 48h, including parameter window and horn/jig suggestion.

Q2. What materials are suitable for ultrasonic welding?
ABS, PC, PA, PP, PE, PMMA, PBT and most thermoplastics. We will confirm based on your material grade.

Q3. How do you ensure cosmetic quality on thin walls?
Servo closed-loop depth/force + programmable motion profile reduces flash/whitening and controls collapse precisely.

Q4. What do you need to quote a machine?
Part drawing/3D, material, wall thickness, target cycle time, and quality specs (leak rate/pull strength).

Q5. Do you support MES or data traceability?
Yes. Machines support data recording and MES ports; curve export available.
