When comparing industrial ultrasonic cleaners, the equipment price is only one part of the purchasing decision. A lower-priced machine may require more batches, more handling, or additional downstream equipment for a particular workload. A useful comparison therefore asks a practical question: what will it cost to produce one part that meets the agreed cleaning requirement?
This guide explains a simple costing method for procurement and production teams. It uses measured process inputs rather than assuming a cleaning-speed improvement or estimating savings from ultrasonic wattage alone.
Define an accepted part before calculating cost
Choose the part family and specify the required result. Record the material, dimensions, contamination, batch quantity, and inspection method. If the requirement includes a residue or particle limit, use that same limit when comparing proposed processes.
Count only accepted parts in the final calculation. Dividing cost by every part placed in the basket can make a process with frequent rework look artificially inexpensive. Keep rejected parts, repeated cleaning cycles, and damaged components visible in the worksheet.
Map the complete workflow
Include loading, cleaning, draining, rinsing, drying, inspection, and unloading. Identify which activities need operator attention and which can run without continuous supervision under the approved operating procedure.
Elapsed batch time and operator labor time are different measurements. For example, an operator may perform another approved task during part of a cleaning cycle. Avoid charging the entire elapsed cycle as hands-on labor unless that reflects the real work arrangement. Equally, do not omit the time needed to move baskets, prepare solution, or complete quality records.
Use the basket loading guide to consider usable space and loading consistency. Nominal tank capacity alone does not establish how many parts fit in a productive batch.
Separate recurring costs from equipment costs
A practical worksheet can group recurring costs into five categories:
- Labor: measured operator time multiplied by the relevant hourly labor cost.
- Utilities: measured electricity and water consumption for the complete process.
- Chemistry and consumables: cleaning solution, filters, and other items actually used.
- Waste handling: the applicable cost of collecting and disposing of used solution and contamination.
- Maintenance and rework: an evidence-based allowance, tracked separately when reliable operating history is not yet available.
For equipment ownership, record the purchase price, necessary accessories, delivery, installation, and any other applicable acquisition costs. Allocate that total across the planned service period or production volume using your company's accounting approach. State the assumptions clearly instead of presenting the allocation as a guaranteed lifetime cost.
Measure energy instead of using the ultrasonic rating
Ultrasonic power, heater power, and total electrical consumption are different quantities. A model's ultrasonic rating does not establish the energy used by the whole cleaning workflow. Initial heating, temperature maintenance, rinsing, drying, and idle periods may also contribute.
When energy cost matters to the buying decision, obtain suitable measurements under representative operating conditions. Use the facility's actual energy tariff and document what the measurement includes. Have appropriate personnel select and use measurement equipment; do not modify the cleaner's electrical installation to produce a cost estimate.
Use a transparent cost-per-part formula
Cost per accepted part = total allocated process cost for the period ÷ number of accepted parts produced in that period.
As a hypothetical arithmetic example, a process with $48 in allocated costs and 120 accepted parts has a cost of $0.40 per accepted part. If the same $48 produces only 96 accepted parts, the figure becomes $0.50. These figures illustrate the calculation only; they are not BIMOSONIC performance, operating-cost, or savings claims.
Use one consistent period for both the numerator and denominator. Do not combine a full month's equipment allocation with one day's output or omit rework costs from only one supplier's comparison.
Test the assumptions that change the result most
Compare a normal workload with lower and higher demand. Review how batch density, acceptance rate, solution replacement, and operator time affect the result. A larger cleaner may reduce the number of batches, but only if the actual loading arrangement and cleaning result support that assumption.
Include operating and cooling intervals from the exact model's manual when estimating daily capacity. Do not assume a standard benchtop cleaner can run continuously for 24 hours. Keep unverified maintenance or service-life assumptions labeled as estimates until operational data becomes available.
Turn the calculation into a purchasing discussion
Ask suppliers to quote the same application and identify the exact equipment, basket, accessories, and process boundaries. A representative sample test can help establish batch size, cycle settings, and acceptance criteria before you finalize a cost model.
For a BIMOSONIC factory quotation, provide your part dimensions, contamination, output target, destination, and required result. Review the model comparison guide and send your application details. Comparing documented process inputs gives your team a clearer basis for equipment selection than purchase price alone.
