【Powder Metallurgy】Six-Tank Automatic Hydrocarbon Cleaning Equipment, Vacuum Ultrasonic Cleaning, Vacuum Steam Drying
——Precision cleaning solution for the whole process of MIM parts/structural parts/gears
Product positioning
The intelligent six-tank continuous cleaning equipment specially designed for powder metallurgy parts (MIM metal injection molded parts, powder metallurgy gears, bearing seats, structural parts) integrates three core modules: vacuum ultrasonic degreasing, vacuum vapor drying, and solvent recycling and regeneration, and achieves a 99.8% organic matter removal rate and 0.1μm blind hole cleanliness for molding lubricants (paraffin-based/PEG), metal powder residues, sintering oil and other pollutants on the surface of powder metallurgy parts. The equipment adopts fully automatic PLC control (supports 200 sets of process formulas), which is suitable for small and medium-sized batch and multi-variety production (5-200kg/hour), which meets the high-precision cleaning needs of powder metallurgy parts before degreasing, sintering and electroplating, and the surface tension of the parts after drying is ≥72mN/m, which effectively improves the compactness of subsequent sintering and coating adhesion (the defective rate is reduced by 40%).

Intelligent control system
1. Whole-process automation
PLC touch screen control:
▶ The 12-inch industrial-grade touch screen supports 3D process simulation, and displays 30 parameters such as vacuum, temperature, and solvent concentration of each tank in real time
▶ Automatic recognition of part type (barcode scan/weight sensor) and matching to the optimal cleaning recipe (e.g. degreasing program for MIM parts, cleaning program before gear sintering)
Safety Interlock Mechanism:
✔ Five-stage explosion-proof design: LEL concentration monitoring (10% LEL), abnormal vacuum alarm (deviation >5%), solvent leak detection (response time<10 seconds)
✔ When the equipment is running, a 300N mechanical locking force is applied to the hatch to prevent misoperation and safety accidents
2. Data traceability and quality control
SPC reports with vacuum curves, solvent conductivity, weight difference before and after drying, and MES system integration (ISO 9001:2015 compliant)
Equipped with a particle counter (0.1μm class) to automatically record residual particle data on the surface of the part after cleaning, it meets the requirements of IATF 16949 automotive quality system
