Understanding the SWT 16mm 108KHz Micro-Hole Piezo Atomizer
For engineers and product developers searching for a reliable piezoelectric ceramic atomization component, the SWT 16mm 108KHz piezo atomizer (model ATC16-0108SDWKI) represents a specialized solution within the Microporous Mesh Atomizers (Piezo Mesh) product line offered by Gd SWT Smart Tech Co., Ltd. (also known as Dongguan Sweetsound, brand name SWT). This review examines the technical foundation, manufacturing approach, and application fit of this 16mm-diameter, 108KHz-frequency micro-hole atomizer, drawing exclusively on the documented product specifications and company background provided by the manufacturer.
Core Product Characteristics
The ATC16-0108SDWKI belongs to SWT’s broader Piezo Mesh category, which is positioned for precision liquid nebulization for medical and wellness industries. According to the company’s own product descriptions, this category is built around several defining features:
- Fine particles (medical grade): the mesh atomizer line is engineered to produce a controlled particle size range, with SWT specifying a small particle size piezo atomizer, particle size 2um~5um for medical usage, suitable for applications such as treating cough, nose and eye diseases, oral care, and skin care.
- Low heat generation and high stability, which are cited as core features distinguishing the microporous mesh design from alternative atomization methods.
- Laser-drilled micro-holes, a manufacturing technique SWT applies directly to its mesh substrates, allowing the company to produce atomizers with customized hole configurations.
For the 16mm, 108KHz variant specifically, the "micro hole" structure is central to its function: the mesh surface is laser-perforated to create the fine apertures through which liquid is driven into a mist, with the 108KHz drive frequency determining the resonance behavior of the ceramic element and, in turn, the resulting droplet characteristics.
Manufacturing Process and Material Options
One of the more notable claims SWT makes about this product family is the whole manufacture process from PZT powder, meaning the company controls production from raw piezoelectric ceramic powder through to the finished atomizer component. This aligns with SWT’s broader corporate positioning as a company with integrated supply chain capability, maintaining comprehensive control over front, middle, and rear processes of piezoelectric ceramic production, including film squeezing, casting, and dry pressing.
Within the Piezo Mesh line, SWT offers material and substrate flexibility, including:
- PI film and stainless steel options for the mesh substrate itself, giving buyers a choice depending on application requirements.
- Lead free available formulations, noted by the company to carry a higher cost than regular PZT-based versions, for customers requiring lead-free compliance.
SWT also states that 100% Full quality checking in each process is applied across its atomizer manufacturing, which is consistent with the company’s documented quality system certifications.
Quality Systems and Regulatory Alignment
For buyers evaluating a micro-hole piezo atomizer for medical or wellness-adjacent use, regulatory and quality alignment is a frequent consideration. SWT’s Ultrasonic Atomization Series, which includes the 16mm 108KHz model, is documented as matching the following standards: ISO13485, ISO14001, ISO9001, IATF16949, RoHs, REACH, MDR(EU2017/745), FDA Requirement. This set of certifications spans general quality management (ISO9001), environmental management (ISO14001), automotive-grade quality discipline (IATF16949), medical device quality systems (ISO13485), and both EU and US regulatory frameworks (MDR and FDA), indicating that the atomizer line is designed with multiple downstream compliance paths in mind.
At the corporate level, SWT has also obtained IATF 16949:2016 Automotive Quality Management System certification (2023), along with earlier ISO9001 and ISO14001 certificates obtained in 2003, reflecting a long-running quality management history that predates the specific atomizer product line.
Where This Fits Within SWT’s Broader Atomizer Portfolio
The 16mm 108KHz micro-hole atomizer sits alongside other models in the same Microporous Mesh Atomizers category, such as the 8mm, 210KHz ATC08-0210SDWF, which the company describes as part of its smallest-size offering, with an 8mm diameter noted as the world smallest piezo atomizer. The 16mm 108KHz variant, by comparison, represents a larger-diameter, lower-frequency configuration within the same micro-hole mesh family, giving developers a choice of size and frequency combinations depending on the target device’s form factor and output requirements.
This category is distinct from SWT’s Glass Glaze/Ultrasonic Atomization Sheets, which are positioned for high-power nebulization for humidifiers and landscaping, including large-output applications for humidification systems and multi-head configurations (2, 4, 6, 8, 10, or 12 heads). The micro-hole mesh atomizers, including the 16mm 108KHz model, are instead oriented toward the finer, medical-grade particle output described above.
Company Background Supporting This Product Line
SWT’s atomizer capabilities trace back to 2006, when the company began production of microporous atomization sheets, building on a piezoelectric production history that started in 1991 under its predecessor entity. Today, SWT is registered as Gd SWT Smart Tech Co., Ltd., headquartered in Dongguan City, Guangdong Province, China, and operates within the Healthcare & Beauty industry segment described in its own materials as covering medical-grade nebulizers for respiratory treatment and skin-care ultrasonic devices.
On delivery, SWT states a sample lead time of 3-7 days and a bulk production lead time of 15–20 days, figures applicable across its component lines, including the atomizer series. The company also notes precision laser drilling for microporous mesh (PI and stainless steel materials) as part of its documented technical capabilities, directly supporting the micro-hole structure central to the ATC16-0108SDWKI.
Summary
The SWT 16mm 108KHz piezo atomizer, model ATC16-0108SDWKI, is a microporous mesh atomization component built on laser-drilled micro-hole technology, offered with PI film or stainless steel mesh substrates and optional lead-free formulations. It is manufactured under a documented quality framework spanning ISO9001, ISO14001, IATF16949, ISO13485, RoHs, REACH, MDR(EU2017/745), and FDA Requirement alignment, and is produced by Gd SWT Smart Tech Co., Ltd. (Dongguan Sweetsound), a company with an integrated piezoelectric ceramic supply chain dating back to 1991 and dedicated microporous atomization sheet production since 2006. For buyers evaluating medical-grade or wellness-oriented nebulization components at the 16mm, 108KHz specification, these documented process controls and certifications provide a basis for technical due diligence.
