Castings Cleaning for a Mexican Die-Casting Plant
An aluminum die-casting plant removed release agent and machining oil with alloy-safe heated cleaning.
LocationNuevo Leon, Mexico
IndustryAluminum Die-Casting
EquipmentLJ-F2400 cleaner with filtration
Commissioned2025
Project Context
Release agent before machining
The plant cast aluminum housings and needed to remove die-release agent, casting oil and particles before machining and coating.
Before LENJEX
Aluminum staining and oil
Aluminum parts risked staining, and release agent and casting oil loaded the bath quickly.
- Die-release agent on cast surfaces
- Risk of aluminum staining
- Casting particles and oil loading
- Need for consistent pre-coating cleanliness
Cleaning Solution
Alloy-safe heated wash with filtration
The LJ-F2400 used alloy-safe chemistry at controlled temperature, with filtration and oil skimming, followed by rinsing and prompt drying.
The process was validated against the aluminum alloy and surface requirement.
Project Outcomes
Cleaning results and process improvements
Performance depends on the workpiece, contamination, chemistry, loading method and acceptance criteria.
- Result 01Release agent and casting oil removed without staining
- Result 02Filtration kept casting particles out of the bath
- Result 03Clean, dry surface for coating and assembly
- Result 04Bath life extended through skimming
