Start with what is on the part
Hangzhou Miaoliang Ultrasonic Technology Co., Ltd. names research, design, production, installation and service in its company introduction. It also offers cleaning-equipment modification and repair. [1] Its public categories include single- and multiple-tank ultrasonic machines, high-pressure spray equipment and related systems. Application references include flanges, bearings, aluminium die castings and machined metal components. [2]
These are upstream manufacturing and maintenance-process references. They do not establish an approved process for a particular excavator component, hydraulic assembly or engineering-machine OEM. Send the real component and its required condition.
Do not choose solely by the largest visible tank or a general “fast cleaning” statement. A quote should identify the intended part family and what has been demonstrated with the proposed equipment.
Make the sample difficult enough to matter
The ML31800 listing discusses blind holes and hard-to-reach contamination, but supplies no residue report, test conditions or model-specific cycle result. Its “at least five times” productivity wording does not specify the manual baseline, loading or inspection method. [3] Use a trial to establish the result for your component.
| Input | Describe it | Record the outcome |
|---|---|---|
| Part and material | Drawing, alloy, coating, geometry, batch variability and surfaces that must remain unchanged. | Sample identity and agreed observations before and after cleaning. |
| Actual contamination | Machining fluid, oil, particles or other known soil, including where it collects and how long it has been present. | The agreed residual-contamination check at the locations that matter. |
| Production loading | Actual basket, orientation, quantity and handling constraints. | The tested loading arrangement and complete processing/handling time. |
| Next operation | Assembly, coating, inspection or storage requirements following cleaning. | Accepted rinse, dry and protection condition before that operation. |
Keep a failed sample as well as a passing one when investigating an unstable process. Agree how variation in soil, material and loading will be handled. A photograph of a bright external surface is not an internal-passage cleanliness report.
Ask who provides the samples, chemistry, baskets and inspection. Agree the trial cost and what data will be returned before shipping valuable components.
Purchase the whole wet-to-dry workflow
Compare quotations at the same boundary: loading, cleaning, rinsing, drying, unloading and any protection or storage step needed by the next operation. Identify every stage actually included; the catalogue image alone does not define its function.
- Process proposal: link the dirty-part trial to the chosen stages and equipment configuration.
- Engineering release: approve tank/basket drawings, controls, utilities, handling and maintenance access.
- Acceptance: repeat the agreed sample and inspection method under recorded loading conditions.
- Installation: confirm commissioning, operator instruction, process settings and site responsibilities.
- Routine operation: agree bath management, consumables, inspection, spare parts and response to an out-of-limit result.
HSE’s engineering-cleaning guidance recommends assessing the actual chemical and operation using supplier information and safety data sheets; it notes that ultrasonics produce heat. [5] This is general safety context. The proposed cleaner, chemical, extraction and waste arrangements need competent review for the real site and destination requirements; no certification is inferred.
Confirm the manufacturing site behind the office contact
Business-registration data names 杭州淼亮超声波科技有限公司, incorporated on 14 April 2015, with registered address Poli Tiandi Centre, building 6, room 514 in Qiantang. The current official contact page gives Yingguan Tiandi City, building 5, room 3008. [4] Both records are retained. Neither office-style address is treated as a verified production plant.
Confirm the quotation issuer, actual equipment production and trial location, commissioning responsibility and after-sales arrangements. The website’s headcount and broad “high-tech” wording are not independently verified qualifications. Request current documents when they matter to the purchase.
The official contact page lists a general mailbox, and a second mailbox is labelled for after-sales.
