Ultrasonic degreasing removes oily contamination from industrial parts by combining a suitable cleaning liquid with ultrasonic agitation. For an equipment buyer, the useful question is whether the complete process leaves the required surfaces ready for the next operation. A clean exterior is insufficient if oil remains in a threaded recess or detergent dries inside a passage. Start with the actual part, its contamination and the required end condition. Then evaluate chemistry, loading, rinsing and drying alongside the cleaning tank.
What ultrasonic action contributes to degreasing
Ultrasonic cleaning uses cavitation in a liquid: bubbles form and collapse, producing local mechanical action that helps loosen contamination. The liquid must reach the surface being cleaned. Ultrasonic energy does not remove the need to consider wetting, trapped air or contact between parts. The explanation of how ultrasonic cleaning works provides background for discussing these limits with an equipment supplier.
Can a more powerful tank compensate for the wrong degreaser? No. Power is an equipment specification, while chemical suitability concerns the particular oil, substrate and required finish. Treat ultrasonic action and cleaning chemistry as complementary parts of the process. During trials, record whether residue remains on exposed faces, protected surfaces or both. That distinction helps frame the next investigation without assuming that every failure requires a larger machine.
Select chemistry around the soil and substrate
Describe the contamination before asking for a detergent recommendation. Identify machining oil, grease or other process residue from its product information where available. Explain whether contamination arrives fresh, after storage or mixed with particles. Supply the part material and any plating, coating, adhesive or assembled component that will contact the bath. A label such as metal parts leaves too much uncertainty for a useful compatibility discussion.
For a proposed aqueous degreaser, ask the chemical supplier about wetting, oil handling, rinsability and compatibility with ultrasonic use. Confirm its permitted operating conditions and the checks needed as the bath becomes contaminated. Do not transfer a concentration or temperature from an unrelated application. The ultrasonic cleaning solution guide is a starting point for selection; approval should rest on the chemistry documentation and tests with the actual parts.
Include the required surface condition in that discussion. Visible oil removal, coating preparation and assembly cleanliness are different acceptance questions. Ask how remaining contamination and cleaner residue will be distinguished. Avoid judging the process from bath appearance alone: a cloudy liquid or an apparently clear part does not establish that the specified surface condition has been achieved.
For mixed-material assemblies, list every exposed material rather than naming only the main body. Agree how the trial will check appearance, coating condition and the areas that matter to function. Review the proposed chemical’s safety data sheet and confirm compatibility with the quoted equipment. Cleaner selection should include operator handling and disposal requirements as well as the ability to remove the incoming soil.
Build the process around access, rinsing and drying
A useful trial follows the intended production route. Record the incoming condition, load arrangement and cleaning settings, then inspect the part after its planned rinse and drying stages. Changing several conditions together makes the result harder to interpret. Keep a record of what changed and why, so the next trial answers a specific question rather than simply producing another clean-looking sample.
- Prepare the load: decide whether heavy loose contamination needs a separate removal step before immersion. Record that step so its contribution is not mistakenly attributed to the ultrasonic tank.
- Expose the surfaces: arrange parts so liquid can enter the features requiring cleaning. Check contact points, overlapping faces and locations where air may remain trapped.
- Rinse deliberately: define how cleaning liquid and loosened contamination leave external surfaces and internal features. Specify the rinse condition as part of the trial.
- Dry and protect: examine pockets that retain liquid and consider handling after drying. Include the intended delay before the next manufacturing operation in the evaluation.
Internal geometry deserves its own inspection plan. A result on a flat coupon cannot establish what happens inside a production component. For recessed features, use the discussion of cleaning blind holes and internal passages to prepare questions about orientation, drainage and verification. Agree how the relevant surfaces will be examined before deciding whether the trial succeeded.
Compare equipment using the actual load
Tank capacity is a starting specification, not a description of the finished process. The JPS-30 series lists a 6 L tank measuring 300 × 150 × 150 mm. The JPS-100 series lists 30 L and 500 × 300 × 200 mm. These dimensions describe the tanks; they do not establish basket clearance, usable load, production output or suitability for a particular oily component.
Use the benchtop ultrasonic cleaner sizing guide alongside a drawing of the intended load. Ask how the basket, part orientation and handling access affect fit. Check the largest component and the proposed batch arrangement, including awkward features that need liquid access. Comparing litres alone can hide a geometry problem that becomes obvious when the load is drawn inside the tank.
The JPS range has adjustable temperature control from 20–80°C and stainless steel inner tanks and outer housings. That control range is not a recommended degreasing temperature. Select the operating condition through chemistry guidance and part testing. Compare the JPS benchtop equipment category against the actual process requirement rather than treating an available setting as an approved recipe.
Specify the surrounding equipment and maintenance
When cleaning must connect with separate rinsing or other process stages, review the industrial multi-tank equipment category. For requirements outside a standard arrangement, discuss the JTM industrial and custom range through non-standard customization. State the required stages and handling method, then ask which features are included in the proposed configuration. Do not assume that filtration, oil separation, transfer equipment or drying is standard.
Ask how operators will monitor bath condition, remove accumulated contamination and decide when service is needed. Define access for draining and cleaning, and clarify responsibilities for chemistry and waste handling. The operation and maintenance guide supports that discussion. A purchase specification should describe the maintenance tasks expected in production as clearly as it describes the initial cleaning trial.
Use sample testing to make the purchase decision
Jietai Ultrasonic offers free cleaning tests using customer-supplied workpieces. Send representative parts and explain the contamination, materials, critical surfaces and intended next operation. Include the acceptance method and any process restrictions. Ask what trial conditions and results can be discussed; the sample-test offer alone does not establish a production capacity, documentation package or guaranteed outcome.
Review the result against the original requirement. Confirm the load arrangement, cleaning liquid, rinse route and drying method associated with the inspected sample. If the proposed production load differs, identify what still needs testing. Close the quotation around the agreed process and equipment scope, with unresolved items recorded explicitly rather than hidden behind a general claim that the part is clean.
Prepare a comparison record that follows the same surfaces through incoming inspection, cleaning and the final process condition. Where inspection requires opening an assembly or examining an internal feature, agree on access beforehand. Retain the failed observations alongside successful samples. They show which arrangements still require investigation and keep an attractive external finish from standing in for evidence about the complete component.
Frequently asked questions
Can ultrasonic degreasing use the existing cleaning chemical?
It is a candidate for evaluation, not an automatic approval. Ask its supplier about ultrasonic use, substrate compatibility, operating conditions and rinsing. Test representative parts with the planned downstream process before accepting the chemical for the equipment.
What if the outside is clean but recesses remain oily?
Check whether liquid reaches the recess and whether trapped air, contact points or retained dirty liquid affect the result. Compare orientations and inspect after rinsing and drying. Avoid changing power alone before establishing which part of the process leaves the residue.
Should procurement choose a benchtop or industrial system?
Base the choice on load geometry, required process stages, handling and acceptance evidence. A benchtop trial can inform selection, but its result does not establish an industrial configuration. Request a proposal that connects each required operation with an explicitly included equipment function.
