Piezo ceramics · Ultrasonic conversion · Application engineering01 / COMPANY PROFILE
Focused on core piezoelectric and ultrasonic components
Our core products are ultrasonic welding ceramic elements, cleaning transducers, atomizing elements and beauty elements. Selection and customization are supported around frequency, power, dimensions, electrical performance and assembly conditions.
From material preparation and ceramic element production to transducer assembly and performance testing, Sunnytec emphasizes design validation, manufacturing stability and batch consistency from prototype confirmation through volume delivery.
OUR CORE BUSINESS
Four product families for clearly defined applications
Welding ceramic elements
Ring-shaped piezoelectric ceramics for ultrasonic welding transducer systems.
↘02Cleaning transducers
For industrial tanks, precision parts and professional cleaning equipment.
↘03Atomizing elements
For humidification, aroma, environmental control and liquid atomization.
↘04Beauty elements
For beauty, cleansing and professional personal-care devices.
↘02 / OUR JOURNEY
Sunnytec established its Shantou manufacturing operation in 1994 with a clear mission: to become a professional supplier of piezoelectric ceramic components. Through sustained development, disciplined production and customer-proven applications, Sunnytec products have grown to serve markets across Asia-Pacific, Europe and North America.
03 / MATERIALS & MANUFACTURING
Understanding materials for stable ultrasonic performance

Piezoelectric formulation, forming and sintering conditions directly influence frequency, capacitance, electromechanical performance and long-term stability. Starting with the application, Sunnytec considers operating frequency, power load, installation dimensions and service environment when matching material and product structure to each ultrasonic system.
Our integrated capability covers in-house design, ceramic powder preparation, element production, transducer assembly and performance testing. Connecting material preparation with final verification provides a clearer manufacturing basis for prototype approval, parameter refinement and subsequent volume production.
04 / QUALITY & VALIDATION
Turning quality into verifiable delivery criteria
Sunnytec achieved ISO 9001 quality system certification in 2000 and applies quality management across incoming materials, production processes and finished-product inspection. Depending on the product, key checks include appearance and dimensions, capacitance, resonant frequency, impedance and insulation performance.
From first-article approval and in-process inspection to final testing, defined inspection requirements support product consistency, with essential batch and test information retained. For customized projects, our technical team reviews assembly conditions and actual operating requirements so prototype validation and volume delivery follow the same acceptance basis.

VISIONOUR AMBITIONTo become a globally recognized supplier of piezoelectric ceramic components and build Sunnytec into a professional, trusted brand.
