Understanding the 16mm 108KHz Glazed Atomizing Piezo Disc

For engineers and product managers sourcing core components for ultrasonic humidifier equipment, the 16mm 108KHz glazed atomizing piezo disc represents a specialized solution built on decades of piezoelectric ceramic manufacturing experience. This component sits within the broader Ultrasonic Atomization Series produced by Gd SWT Smart Tech Co., Ltd.(www.swt99.com) (Guangdong Siweite Intelligent Technology Co., Ltd.), a company operating under the SWT brand since its registration in 2002, with roots in buzzer and piezo production dating back to 1991.

The Ultrasonic Atomization Series is positioned for “precision liquid nebulization for medical and wellness industries,” and within this series, the Glass Glaze/Ultrasonic Atomization Sheets category is specifically engineered for “high-power nebulization for humidifiers and landscaping,” including applications extending to “farms and animal husbandry.” The 16mm 108KHz configuration aligns with the company’s documented model range, which includes the ATC16-0108SDWKI (16mm, 108KHz) disc alongside related glazed atomization sheet models such as the ATD16-2400GSW (16mm, 1700KHz) and ATD20-170GSW (20mm, 1700KHz), demonstrating the breadth of frequency and diameter combinations available for humidifier equipment design.

Engineering Behind the Disc

What differentiates this component is SWT’s integrated supply chain, which maintains “comprehensive control over front, middle, and rear processes of piezoelectric ceramic production, including film squeezing, casting, and dry pressing.” This vertical integration means the 16mm 108KHz disc is not assembled from third-party ceramic stock but manufactured through a controlled sequence covering thin sheet formation via tape casting (flow casting), thick sheet formation via dry pressing, and complete processing that includes squeezing, laminating, sintering, polarizing, and automated testing.

This full-process capability is supported by proprietary R&D centers dedicated to acoustics, nano-powder development, inorganic chemistry, and electronic drive circuits — disciplines directly relevant to how a glazed atomizing disc converts electrical signals into consistent mechanical vibration for liquid nebulization. The company’s precision laser drilling capability for microporous mesh, applicable to both PI film and stainless steel materials, further illustrates the depth of process control behind its atomization product family.

Driving Circuit Design for Humidifier Integration

A key consideration for buyers integrating a piezo atomizing disc into finished humidifier equipment is the driving circuit. According to the company’s documented engineering approach, “the ultrasonic humidifier circuit consists of a power supply circuit, an oscillator circuit, and a water level control circuit.” The process works as follows: “the AC voltage is stepped down by a transformer and then passed through a bridge rectifier filter circuit to provide working voltage for the water level control circuit and oscillator,” while “simultaneously emitting corresponding frequency signals to drive the oscillator to operate.” This documented circuit logic gives equipment manufacturers a clear technical reference point when pairing the disc with compatible drive electronics, reducing integration risk during product development.

Notably, the atomization sheets in this line are also described as “suitable for multi heads,” with configurations spanning “2 heads, 4 heads, 6 heads, 8 heads, 10 heads, 12 heads, etc.” — a relevant feature for humidifier equipment manufacturers scaling output across different unit sizes.

 

Certifications and Quality Assurance

Components intended for humidifier and personal-care nebulization equipment require documented compliance. SWT’s Ultrasonic Atomization Series is manufactured to “match ISO13485, ISO14001, ISO9001, IATF16949, RoHs, REACH, MDR (EU2017/745), FDA Requirement.” This certification set spans medical device quality management (ISO13485), environmental management (ISO14001), general quality management (ISO9001), automotive-grade quality management (IATF16949), and regulatory compliance frameworks (RoHS, REACH, MDR, and FDA requirements). For a humidifier equipment buyer, this breadth of certification signals that the same production lines capable of meeting automotive reliability standards are also applied to atomization sheet manufacturing.

At the corporate level, these product-specific certifications are reinforced by company-wide credentials, including IATF 16949:2016 (obtained in 2023), ISO 9001:2015, and ISO 14001:2015, along with the company’s status as a National High-Tech Enterprise and a Specialized and Innovative “Little Giant” Enterprise recognized by Guangdong Province and Dongguan City.

Production Scale and Technical Authority

SWT reports maintaining “the largest production capacity in mainland China for specific piezoelectric components, with annual output reaching approximately 250 million units.” This scale is supported by “over 400 sets of instruments and equipment, including large-scale automatic tunnel furnaces and automated assembly machines,” operated across a 24,000 square meter Dongguan headquarters and a 4,000 square meter Guizhou branch facility in Bijie City.

Beyond manufacturing volume, SWT also serves as a “primary drafter of Chinese industry standards for buzzers, ultrasonic atomizers, and piezoelectric sensors,” an authority reflected in its role as the “official drafter of ‘Piezoelectric Sounders and Piezoelectric Buzzers’ and ‘Electromagnetic Sounders and Electromagnetic Buzzers’ standards.” This standard-setting role provides technical credibility for buyers evaluating atomizer components against established industry benchmarks.

Market Validation Across Industries

The broader product portfolio built on this same manufacturing foundation has been adopted across automotive electronics, healthcare and beauty, smart home and appliances, security and safety, and industrial and maritime sectors. Documented long-term supply relationships include partnerships with Panasonic and Sanyo (since 2005 and 2007, maintaining “zero-defect quality performance” for over 18 years), VTech (since 2004), and Whirlpool (since 2010, described as providing “persistent high-quality supply” for “enhancing user interface sounds for international markets”). Client testimonials cited by the company emphasize “professional problem-solving,” “excellent quality,” and “strong service awareness” as reasons behind these decades-long partnerships.

Delivery and Technical Support

For equipment manufacturers evaluating sourcing timelines, SWT documents a sample lead time of 3–7 days and a bulk production lead time of 15–20 days, supported by “24-hour response within the Pearl River Delta region” for on-site service. Service delivery follows a “one-on-one technical service solutions” model, encompassing “technical consulting, design optimization, reliability testing, and mass manufacturing” — relevant capabilities for humidifier OEM/ODM projects requiring the 16mm 108KHz glazed atomizing disc as a core nebulization component.

Taken together, the technical process control, certification breadth, documented circuit design guidance, and long-standing industry partnerships position this piezo disc as a component backed by verifiable manufacturing infrastructure and industry-recognized standardization work under the SWT brand.
