I. Main Challenges in Stamped Parts Cleaning

Stamped parts accumulate various contaminants during production:

• Stamping oil / drawing oil: Lubricants used in the stamping process

• Metal chips: Iron filings and dust generated from stamping

• Oxide layers: Surface oxidation formed during storage

• Polishing wax / rust preventive oil: Residues from subsequent surface treatments

II. Types of Solvent Cleaning Machine Solutions

1. Hydrocarbon Vacuum Cleaning Solution (Recommended for high-precision stamped parts)

Applicable Scenarios: Precision automotive stamped parts, battery pack stamped parts, stainless steel stamped parts

Process Flow:

Loading → Vacuum Ultrasonic Cleaning → Vacuum Rinsing → Vapor Degreasing → Vacuum Drying → Unloading

Core Advantages:

• Reduced hydrocarbon solvent boiling point under vacuum, enabling vapor cleaning at around 80°C

• Vacuum flash-boiling effect shortens drying time to within minutes

• Solvent recovery rate exceeds 95%, resulting in low operating costs

• Extremely strong dissolving power for mineral oils and stamping oils (similarity-intermiscibility principle)

Typical Equipment Parameters:

• Main unit dimensions: 5800×2000×3000mm

• Equipment weight: 5500Kg

• Cleaning cycle: Adjustable (typically 2-5 minutes per basket)

2. Modified Alcohol Cleaning Solution (For stamping oils containing chlorinated paraffins)

Case Study: BK Stanz- und Umformtechnik (German stamped parts manufacturer)

• Utilizes DOWCLENE™ 1601 modified alcohol solvent

• Combined with MAXISTAB™ stabilizer

• Effectively cleans chlorinated stamping oils, meeting automotive industry quality requirements

Results:

• Significant reduction in rework time

• Substantial improvement in part quality

• Higher process stability

3. Fully Automatic Multi-Tank Ultrasonic Cleaning Solution (For high-volume production)

Typical Process Configuration:

Equipment Features:

• Fully enclosed structure with PLC automatic control

• Multi-arm robotic transfer of cleaning baskets

• 360° rotary cleaning ensuring no dead angles

• Capacity: Approximately 35Kg per basket, 5 minutes per basket

III. Cleaning Solution Selection by Stamped Part Material

IV. Key Technical Points for Stamped Parts Cleaning

1. Application of Vacuum Technology

• Air removal: Under vacuum, air on workpiece surfaces, in blind holes, and gaps is expelled, allowing complete cleaning agent penetration

• Reduced boiling point: Hydrocarbon solvents' boiling point decreases under vacuum, enabling low-temperature vapor cleaning

• Rapid drying: Vacuum flash-boiling effect causes rapid cleaning liquid volatilization, reducing drying time from 1 hour to minutes

• Solvent regeneration: Vacuum distillation enables solvent recycling

2. Ultrasonic Parameter Optimization

• Frequency selection: 28KHz (general oil contamination) or 40KHz (precision parts)

• Power density: Adjusted according to oil contamination level, typically 1800W per tank

• Temperature control: Water-based cleaning at 50-70°C, hydrocarbon cleaning at around 80°C

3. Cleaning Effect Verification

• Cleanliness standard: Achieve electroplating-grade or coating-grade cleanliness requirements

• Residue detection: No oil or impurity residues, and no deformation after drying

• Rust prevention performance: Short-term rust prevention capability after cleaning (7-30 days)
