Understanding the 13.8mm 130KHz Micro-Hole Piezo Atomizer Category
For engineers and product developers searching for a 13.8mm 130KHz piezo atomizer with micro hole design, the core requirements typically center on three factors: precise particle output, manufacturing consistency, and the ability to customize hole configuration for specific liquid delivery applications. Gd SWT Smart Tech Co., Ltd. (operating under the brand SWT, and known in the industry as Dongguan Sweetsound) addresses these requirements through its Microporous Mesh Atomizers (Piezo Mesh) product line, part of the company’s broader Ultrasonic Atomization Series.
Product Line Positioning and Core Technical Features
SWT’s Microporous Mesh Atomizers are positioned for precision liquid nebulization across medical and wellness industries. The product family is engineered around several core features: fine particles (medical grade), low heat generation, and high stability during operation. These characteristics are directly relevant to any 13.8mm-class atomizer intended for controlled micro-hole nebulization, where consistent droplet formation and thermal stability are essential.
Within this line, SWT’s published reference models include the ATC16-0108SDWKI (16mm, 108KHz) and the ATC08-0210SDWF (8mm, 210KHz), which illustrate the company’s demonstrated range of diameter and frequency combinations—from 8mm up to 16mm, and from 108KHz to 210KHz. A configuration such as 13.8mm at 130KHz falls within this established engineering range, reflecting SWT’s capacity to tailor diaphragm diameter and resonant frequency to customer-specific micro-hole atomization requirements, including customized holes as noted in the company’s product documentation.
Manufacturing Process: From Powder to Finished Micro-Hole Mesh
A key differentiator highlighted in SWT’s technical documentation is that the whole manufacture process for its piezo atomizers starts from PZT powder, giving the company direct control over material composition rather than relying on externally sourced ceramic substrates. This is paired with laser-drilled micro-holes, a precision manufacturing step that defines the atomization mesh’s hole geometry and, by extension, the resulting particle size distribution.
SWT further notes that it has produced the smallest size 8mm piezo atomizer in the world, demonstrating the miniaturization capability that underpins its broader micro-hole atomizer range, including mid-range diameters such as 13.8mm. For customers requiring alternative material chemistries, lead-free options are available, though the company is transparent that this option carries higher cost than regular PZT.
Quality Assurance and Material Options
Every unit in this category undergoes 100% full quality checking in each process, a quality control philosophy applied consistently across SWT’s atomization product line rather than as a one-time inspection step. Customers can also select between PI film and stainless steel mesh material options, allowing the atomizer construction to be matched to the intended application environment, whether that involves chemical exposure, biocompatibility needs, or mechanical durability requirements.
Medical-Grade Particle Performance
Among the technical claims most relevant to a 130KHz micro-hole configuration is SWT’s stated particle size range of 2um to 5um for its small particle size piezo atomizers designed for medical usage. According to the company’s documentation, this particle range is applied to nebulization for treating cough, nose and eye diseases, oral care, and skin care. This causal relationship—fine, laser-drilled micro-holes producing a controlled 2um–5um particle range suitable for respiratory and topical medical applications—is central to why precision hole manufacturing matters for atomizers in this size and frequency class.
Certifications Supporting Medical and Industrial Deployment
For buyers evaluating a 13.8mm 130KHz atomizer intended for regulated markets, SWT’s Ultrasonic Atomization Series is documented as matching ISO13485, ISO14001, ISO9001, IATF16949, RoHs, REACH, MDR (EU2017/745), and FDA Requirement standards. This combination of medical device (ISO13485, MDR, FDA) and automotive/industrial (IATF16949) certifications indicates that the same manufacturing discipline applied to consumer and industrial piezo components extends to atomizer products intended for healthcare-adjacent use cases.
Company Background Supporting Manufacturing Depth
SWT’s atomizer capabilities are grounded in a longer corporate history. The company began professional buzzer production and technology accumulation in 1991, later formalizing its SWT brand identity in 2002 after relocating to Dongguan City. By 2006, the company had already begun production of microporous atomization sheets, giving its atomizer line nearly two decades of accumulated process experience by the current date. This is consistent with SWT’s broader positioning statement that it maintains self-developed and self-manufactured processes across 25 years of cumulative experience.
The company operates as a high-tech joint-equity enterprise and a recognized Specialized and Innovative SME, supported by proprietary R&D centers covering acoustics, nano-powder, inorganic chemistry, and electronic drive circuits. Manufacturing infrastructure includes over 400 sets of instruments and equipment, including automated assembly machines, and the company reports an annual shipping capacity of approximately 250 million pieces for piezoelectric ceramic elements, alongside precision laser drilling for microporous mesh using both PI and stainless steel materials—the same drilling capability that defines micro-hole atomizer construction.
Delivery and Customization Capability
For customers requiring a specific 13.8mm 130KHz configuration, SWT’s stated service model includes one-on-one technical service solutions and customized product development (OEM/ODM). Documented delivery timelines include a sample lead time of 3-7 days and a bulk production lead time of 15-20 days, supporting both prototyping and volume manufacturing needs for custom atomizer specifications.
Industry Application Context
Within SWT’s documented industry coverage, the Healthcare & Beauty segment is specifically described as encompassing medical-grade nebulizers for respiratory treatment and skin-care ultrasonic devices—directly aligned with the therapeutic use cases (cough, nasal, eye, oral, and skin care) associated with fine-particle micro-hole atomizers. The company’s broader Smart Home & Appliances coverage also references USB humidifiers, indicating that atomizer technology at SWT spans both medical-grade and consumer humidification applications, differentiated primarily by particle size and hole configuration.
Summary for Technical Buyers
For a 13.8mm 130KHz piezo atomizer with micro-hole design, the relevant technical foundation documented by SWT includes: full in-house PZT powder-to-finished-product manufacturing, laser-drilled micro-hole precision, a demonstrated 2um-5um particle range for medical applications, dual material options (PI film and stainless steel), 100% in-process quality checking, and certification coverage spanning ISO9001, ISO13485, IATF16949, MDR, and FDA requirements. These documented capabilities position SWT’s Microporous Mesh Atomizer line as a technically substantiated option for customers evaluating micro-hole atomizer specifications within this diameter and frequency range.
