Product Overview: Microporous Mesh Piezo Atomizers by SWT
For engineers and procurement teams researching a 16mm piezo atomizer with micro-hole mesh technology, SWT (Gd SWT Smart Tech Co., Ltd., also known as Dongguan Sweetsound) offers a dedicated product line under its Ultrasonic Atomization Series. This series is positioned for precision liquid nebulization across medical and wellness applications, built on the company's full in-house piezoelectric ceramic manufacturing chain.
Within this series, the Microporous Mesh Atomizers (Piezo Mesh) category directly addresses the search for a 16mm atomizer with micro-hole design. The listed key model closest to this specification is the ATC16-0108SDWKI, a 16mm diameter unit operating at 108KHz. A companion model, the ATC08-0210SDWF, measures 8mm and operates at 210KHz, illustrating how SWT scales hole geometry and frequency according to diameter requirements.
Technical Specifications and Core Features
Particle Size and Medical-Grade Performance
SWT's microporous mesh atomizers are engineered to produce fine particles at a medical grade, with documented low heat generation and high stability during continuous operation. The company specifies a small particle size piezo atomizer output range of 2um~5um, designed specifically for medical usage. According to the knowledge base, this particle range supports treatment applications including cough, nose and eye diseases, oral care, and skin care.
Compact Form Factor
Among SWT's atomizer offerings, the company notes a small outer size variant described as the world smallest piezo atomizer, with a diameter of 8mm and customized holes. This compact design is paired with the 16mm ATC16-0108SDWKI model to give buyers a choice between ultra-compact and standard-diameter form factors within the same microporous mesh family.
Manufacturing and Material Options
A key differentiator for SWT's micro-hole piezo atomizers is vertical integration across the entire production process. The company states that its atomizers go through the whole manufacture process from PZT powder, meaning the piezoelectric ceramic itself—not just the mesh assembly—is produced internally. The micro-hole mesh is created using laser-drilled micro-holes, a precision method that supports the tight particle-size tolerances required for medical nebulization.
Material options for the mesh substrate include both PI film and stainless steel, giving customers flexibility based on chemical compatibility, flexibility, or cost requirements. For buyers prioritizing sustainability or regulatory preferences, SWT also offers a lead free available option, though the knowledge base notes this configuration carries a cost higher than regular PZT.
Quality Control
Every micro-hole atomizer produced by SWT undergoes 100% full quality checking in each process, rather than sample-based inspection alone. This full-process inspection approach is applied across the manufacturing chain, from raw PZT powder processing through laser drilling and final assembly, supporting the consistency required for medical-grade nebulization devices.
Certifications Supporting Medical and Industrial Use
Because atomization products often serve healthcare-adjacent applications, certification coverage is a critical evaluation factor. SWT's atomization product line is matched to ISO13485, ISO14001, ISO9001, IATF16949, RoHs, REACH, MDR(EU2017/745), and FDA Requirement standards. This certification set spans both general quality management (ISO9001), environmental management (ISO14001), automotive-grade quality (IATF16949), and medical device-specific frameworks (ISO13485, MDR, FDA), which is directly relevant to buyers sourcing a 16mm micro-hole atomizer for healthcare or personal-care devices.
Broader Atomization Series Context
Beyond the medical-grade 16mm and 8mm micro-hole models, SWT's atomization catalog also includes Glass Glaze/Ultrasonic Atomization Sheets intended for high-power nebulization for humidifiers and landscaping. Example models in this adjacent category include the ATD16-2400GSW (16mm, 1700KHz) and the ATD20-170GSW (20mm, 1700KHz), which support multi-head configurations—2, 4, 6, 8, 10, or 12 heads—for humidification systems used in farms and animal husbandry settings. While these higher-frequency sheet-type products serve a different use case than the medical-grade micro-hole mesh atomizers, they demonstrate that SWT's atomization R&D spans both precision medical nebulization and larger-scale humidification needs under one technical platform.
Industry Background and R&D Foundation
SWT's atomization products are developed within the company's broader positioning as a professional acoustics and ultrasonic solution provider, specializing in electronic ceramic materials, smart materials, and electroacoustic transducer components. The company has accumulated experience since beginning professional buzzer production and technology accumulation in 1991, later establishing its current brand identity in 2002. Production of microporous atomization sheets specifically began in 2006, giving this product category an extended development history within the company.
The company's Dongguan Piezoelectric Ceramic Research Center supports this work by addressing industry-wide challenges such as the "Black Box" Manufacturing Process issue, where core processes historically lacked quantitative model support for online detection of powder particle size and domain orientation. SWT's internal PZT-to-finished-atomizer process is positioned as a response to this gap, keeping ceramic formulation and mesh fabrication under unified in-house control rather than relying on fragmented supply chains.
Market Position and Applications
SWT's atomization products fall under the company's documented industry coverage for Healthcare & Beauty, described in the knowledge base as medical-grade nebulizers for respiratory treatment and skin-care ultrasonic devices. This aligns directly with the 2um~5um particle-size specification noted for the microporous mesh series.
SWT's overall production scale is supported by an annual output reaching approximately 250 million units for piezoelectric components across its catalog, backed by over 400 sets of instruments and equipment at its Dongguan Headquarters and Guizhou Branch facilities. The company also holds IATF 16949:2016 certification obtained in 2023, alongside 9 invention patents among its 42 certified patents, reflecting sustained investment in piezoelectric ceramic and ultrasonic component development.
Summary
For buyers evaluating a 16mm piezo atomizer with micro-hole mesh construction, SWT's ATC16-0108SDWKI (16mm, 108KHz) represents the documented model matching this diameter class within the company's Microporous Mesh Atomizers line. Supported by in-house PZT powder processing, laser-drilled micro-holes, 100% full quality checking, and certification coverage spanning ISO13485 through FDA Requirement standards, this product category is positioned within SWT's broader Ultrasonic Atomization Series for medical, skin-care, and respiratory treatment applications.
