Is it better to use a regular ultrasonic cleaning machine or an electrolytic ultrasonic cleaning machine for industrial die-casting molds?

For the cleaning needs of industrial die-casting molds, choosing an electrolytic ultrasonic cleaning machine is more suitable, but it needs to be comprehensively judged based on specific working conditions (such as dirt type, mold material, efficiency requirements, etc.). Here are detailed comparisons and suggestions:

1. Typical dirt on die-casting molds:

Residual release agent (silicone oil, wax, etc.)

Metal oxide (high-temperature oxide layer)

Carbon deposition (carbonization of oil or plastic residue)

Sintered particles (attached to aluminum alloy/zinc alloy)

2. Comparison between ordinary ultrasonic and electrolytic ultrasonic cleaning machines

Choose Electrolytic Ultrasonic for:

✓ Hardened deposits (oxides, carbon)

✓ Complex mold geometries (deep slots, tiny holes)

✓ Long-term cost & eco-efficiency

Ordinary Ultrasonic is sufficient for:

✓ Light cleaning (fresh mold release agents)

✓ Non-conductive parts (plastic/rubber inserts)

✓ Budget-limited projects

3. Recommended scenarios for electrolytic ultrasonic cleaning machines

Mold condition: Long term uncleaned, with stubborn oxide layer or carbon deposition. The mold has complex structures such as deep holes and fine seams.

Efficiency requirement: The cleaning time needs to be shortened (electrolysis+ultrasound is 30%~50% faster than pure ultrasound).

Environmental protection requirements: We hope to reduce the use of strong acids and bases and lower the difficulty of waste liquid treatment.

4. Situations that can still be considered for ordinary ultrasonic cleaning machines

Limited budget: The cost of electrolysis equipment is relatively high (about 1.5 to 2 times that of ordinary equipment).

The dirt is relatively simple: for example, only short-term release agent residue from the new mold needs to be removed.

Non metallic components: such as plastic inserts, sealing rings, etc. (electrolysis function needs to be turned off).

5. Practical application suggestions

Optimization of electrolysis parameters:

For aluminum alloy molds: weak alkaline electrolyte (pH 9-11) is used to avoid corrosion.

For steel molds: neutral salt solution can be used, with a current density controlled between 0.5~2 A/dm ².

Supporting measures:

Pre spray before cleaning to remove large particle residues.

After cleaning, dry and rust proof treatment (especially for precision mold cores).

conclusion

Prioritize choosing electrolytic ultrasonic cleaning machines, especially for die-casting molds that have been used for a long time and have stubborn dirt. If the budget is limited or the dirt is light, you can first use a regular ultrasonic cleaning machine to test the effect, and then upgrade later.
