The core of Buck’s cleaning solutions for automotive stamping parts is to select three mainstream processes — vacuum ultrasonic cleaning with hydrocarbon solvent, continuous high-pressure spray cleaning, and flexible precision cleaning centers — based on part size, structural complexity, cleanliness requirements and production capacity. Our solutions deliver superior cleanliness, high productivity and eco-friendly operation.

1. Typical Working Conditions & Core Pain Points

Automotive stamping parts include body panels, structural components and small precision stampings. Common contaminants are stamping oil, drawing oil, iron filings, dust and scale.Major challenges: residual dirt in deep holes, blind holes and gaps; inconsistent cleaning quality in mass production; strict cleanliness standards (VDA 19, ISO 16232) for subsequent painting, welding and assembly processes.

2. Three Core Cleaning Solutions from Buck

2.1 Hydrocarbon Vacuum Ultrasonic Cleaning Solution

Application: Small stamping parts, precision fasteners and irregular complex components such as clips, brackets and spring plates.

Process Flow: Vacuum degassing → Rough ultrasonic cleaning → Fine ultrasonic cleaning → Vapor rinsing → Vacuum drying. Fully enclosed solvent circulation system with zero wastewater discharge.

Advantages:

• Cleanliness: Complies with VDA 19 / ISO 16232 Class B standards; no water stains or residues.

• Safety: UL & CE explosion-proof certified, suitable for high-end production lines.

• Environmental protection: Solvent recovery rate ≥ 98%; consumption as low as 0.02L per piece.

2.2 Continuous High-Pressure Spray Cleaning Solution

Application: Large & medium-sized parts including automotive body panels, door/hood inner panels and chassis structural parts; compatible with automated assembly lines.

Process Flow: High-pressure spray for chip removal (50–100 MPa) → Chemical degreasing → Multi-stage rinsing → Hot air drying. 360° rotating nozzles ensure full coverage of deep cavities and gaps.

Advantages:

• High efficiency: Cycle time 1–3 minutes per piece, capacity 20–100 pieces per hour.

• Powerful cleaning: Pulsed high-pressure spray removes heavy oil films and micron-scale iron filings.

• Reliable performance: Full 304 stainless steel structure; 3-stage filtration (5–20 μm) prevents secondary contamination.

2.3 Flexible Precision Cleaning Center

Application: New energy vehicle drive housings, subframes and integrated die-cast parts with numerous deep cavities, oil galleries, intersecting holes and blind holes.

Process Flow: Robotic loading & unloading → Targeted spray cleaning → Turbulent flushing → Vacuum ultrasonic cleaning → Hot air drying. Quick-change flexible fixtures for fast product switching.

Advantages:

• Dead-spot free cleaning: Combined targeted spray and turbulent flushing remove metal chips and release agents inside internal oil passages.

• High flexibility: Compatible with multiple product types; product changeover within 15 minutes.

• Intelligent operation: Built-in AI process database and real-time monitoring; traceable cleanliness data.

3. Solution Selection Guide

• Small precision parts (≤5kg) & stringent cleanliness (VDA 19): Hydrocarbon vacuum ultrasonic cleaning machine

• Large & medium-sized parts (5–50kg) & mass production (≥50 pieces/hour): Continuous high-pressure spray cleaning line

• Complex structures with deep cavities/intersecting holes & mixed production of multiple models: Flexible precision cleaning center

4. Core Strengths & Application Benefits

1. Compliance & Safety: UL & CE explosion-proof design; fully enclosed structure with low VOC emissions, meeting environmental regulations.

2. Cost Optimization: Recyclable hydrocarbon / modified alcohol solvents and zero wastewater discharge cut costs on chemicals and waste disposal.

3. Stable Quality: Consistently qualified cleanliness reduces rework in follow-up processes and improves first-pass yield.

4. Line Compatibility: A database of over 200 mature industrial processes; customized design for seamless integration with existing production lines.

5. Typical Application Cases

• New energy vehicle drive housings: Adopts flexible precision cleaning center. Cycle time: 2.2 minutes per piece; Cleanliness: ISO 16232 Class B; Solvent consumption: 0.02L per piece.

• Small automotive stamping parts: Adopts hydrocarbon vacuum ultrasonic line. Batch capacity: 1,000 pieces per batch; Zero water stains and residues, fully meeting VDA 19 requirements.
