When selecting an ultrasonic cleaner for parts degreasing, evaluate workpiece material, oil contamination, production volume and cleanliness requirements instead of only comparing prices.

First, identify workpieces and contaminants. Machined parts usually carry cutting oil, drawing oil and heavy grease. For heavy oil and cast iron parts, 28kHz low-frequency models deliver strong cavitation impact. For precision small parts, aluminum and thin-wall components, 40kHz or higher medium frequency is recommended for gentle cleaning to prevent surface damage. The tank size must be larger than your maximum workpiece, leaving space for baskets. 304 or 316 stainless steel tanks are preferred for corrosion resistance and long continuous industrial operation.

Second, check ultrasonic power and functions. Power should match tank volume; insufficient power causes poor cleaning results. Built-in heating improves degreasing efficiency, with 50–70°C being the common working temperature. Sweep and degas functions are recommended for parts with blind holes, micropores and threads to eliminate dead zones.

Next, decide automation level. Single-tank machines suit small-batch workshops. Multi-tank systems or fully automatic cleaning lines are ideal for mass production requiring rinsing and drying, and can integrate with production lines.

Finally, verify supplier capability. Choose industrial manufacturers that offer sample testing and non-standard customization. Sinobakr provides custom ultrasonic degreasing solutions based on your part samples, oil conditions and capacity demands, solving machined parts degreasing challenges, reducing labor and solvent costs.
