What products and industries are suitable for the 38L ultrasonic cleaning machine ?

The 38 liter (38L) ultrasonic cleaning machine is a medium-sized industrial equipment, suitable for scenarios that require batch cleaning or larger workpieces. The industries and products it is applicable to mainly depend on cleaning needs (such as degreasing, rust removal, polishing, coating removal, etc.) and ultrasonic frequencies (such as 28kHz, 40kHz, etc.). The following are typical application areas:

1. Applicable industries

(1) Industrial Manufacturing&Automotive Industry

Product example:

Metal components (bearings, gears, piston rings, engine parts).

Precision molds, stamping parts, cutting tools (to remove cutting fluid and oil stains).

Pre treatment of electroplating/spraying (removal of oxide layer, degreasing).

Advantages: Efficient removal of heavy oil stains and polishing residues, improving electroplating/spraying adhesion.

(2) Electronics&Semiconductors

Product example:

PCB circuit board (solder residue, dust cleaning).

Electronic connectors, wafer carriers, SMT surface mount fixtures.

Heat sink (remove aluminum shavings and residual thermal paste).

Attention: Neutral or weakly alkaline cleaning agents should be used to avoid corrosion of precision components.

(3) Medical&Laboratory

Product example:

Cleaning of surgical instruments (hemostatic forceps, orthopedic tools) before sterilization.

Removal of organic residue from glassware (test tubes, beakers).

Cleaning of dental molds and implants (titanium alloy components).

Key point: Medical grade cleaning agents must be used and comply with disinfection standards (such as FDA/CE certification).

(4) Jewelry&Optical Devices

Product example:

Gold and silver jewelry (remove polishing wax and oxide).

Glasses frame and lens mold (clean and undamaged).

Watch movement parts (precision degreasing).

Suggestion: Use high frequencies above 40kHz to avoid scratching the glossy surface.

(5) Aerospace&Energy

Product example:

Turbine blades (excluding carbon deposits and cleaning cooling holes).

Solar silicon wafers, fuel cell components.

Hydraulic valve components, fuel injectors.

Special requirements: Corrosion resistant cleaning solution (such as hydrocarbon solvents) and explosion-proof design (flammable environment) are required.

2. Advantages and limitations of 38L capacity

Advantages:

Suitable for small and medium-sized batch cleaning (such as 20-50 small parts/time).

Can handle larger individual workpieces (such as 30cm long shafts, molds).

Limitations:

Not suitable for ultra large components such as car wheels and whole steel plates.

Need to match heating function (such as 60 ℃) to improve cleaning efficiency.

3. Suggestions for cleaning parameters

Frequency selection:

28kHz: Heavy dirt (sludge, rust), metal parts.

40kHz: Precision parts (electronics, jewelry), small pores.

Cleaning agent:

Metal parts: alkaline or water-based degreaser.

Plastic/Coating: Neutral pH solvent.

Time/Temperature:

Generally 5-15 minutes, temperature 40-60 ℃ (adjusted according to the material's temperature resistance).

4. Selection suggestions

If cleaning coated corrosion parts (such as anti-corrosion valves):

Choose adjustable frequency (switching between 28/40kHz) to avoid coating detachment.

If used in the laboratory:

Ensure that the material of the inner groove is 316 stainless steel or PP plastic (resistant to chemical corrosion).
