Selecting Ultrasonic Transducers & Boosters: The REBAN Guide to Efficiency and Durability
In industrial ultrasonic applications—whether it’s plastic welding, precision machining, or battery manufacturing—the “heart” of the system lies in two critical components: the Transducer and the Booster (Amplitude Transformer).
The Transducer: Converts electrical energy into high-frequency mechanical vibration.
The Booster: Amplifies and directs that vibrational energy to the work area.
At REBAN, with 15 years of precision manufacturing heritage, we know that the difference between a machine that lasts months and one that lasts years comes down to two factors: Material Science and Process Integrity.
1. Material Selection: The Foundation of Acoustic Power
Choosing the right material is the first step in minimizing energy loss and preventing structural failure under high-frequency stress.
The Transducer Core
REBAN utilizes high-grade PZT-8 Piezoelectric Ceramics, known for superior conversion efficiency (reaching ~90%). We pair these with high-strength Titanium or Alloy Steel matching blocks to ensure stable resonance and minimal heat generation.
The Booster (Amplitude Transformer)
Since the booster endures constant high-frequency vibration, fatigue resistance is paramount. We offer three primary material paths tailored to your application:
Titanium Alloy (Premium): The gold standard. Offers the highest fatigue strength and lowest acoustic loss. Ideal for high-end medical, aerospace, and new energy sectors.
Alloy Steel (Standard): Excellent mechanical strength and cost-efficiency. Perfect for heavy-duty industrial welding and high-power applications.
Aluminum Alloy (Light-Duty): Highly machinable and cost-effective. Best for low-power or disposable tooling, often finished with Hard Anodizing to improve surface hardness.
2. Manufacturing Mastery: Eliminating Internal Stress
The most common cause of booster failure is internal stress. If the manufacturing process isn’t controlled, the part will develop micro-cracks and eventually shatter during operation.
Advanced Stress Relief
REBAN employs specialized machining techniques to ensure the metal grain structure is uniform. By controlling the density gradient from the input to the output end, we eliminate the residual stresses that lead to premature fracture.
Precision Engineering Steps:
1.Geometric Optimization: Whether you require a Stepped design (for high gain) or an Exponential design (for uniform energy distribution), our CNC centers maintain tolerances within microns.
2.Surface Refinement: We use precision grinding and polishing to achieve a mirror finish. This reduces air resistance during vibration and prevents “hot spots.”
3.Specialized Surface Treatments: Options include Anodizing, Sandblasting, or Laser Etching to enhance corrosion resistance—critical for parts exposed to electrolytes in the battery industry.
4.Calibrated Assembly: We utilize precision torque tools to ensure the transducer-booster connection is set exactly between 20–25 N·m, preventing thread damage while maintaining perfect acoustic resonance.
3. Why REBAN is Your Trusted Partner for Ultrasonic Components

REBAN Pro-Tip: Avoid the “Efficiency Trap”
Don’t settle for “cheap” materials to save on initial costs. A poorly made booster can lead to transducer burn-out, causing downtime that costs far more than the part itself. Trust REBAN’s 15 years of experience to get the material and process right the first time.
