I. Targeted at the amphoteric property of aluminum, fundamentally solving industry pain points including corrosion, whitening and water stains

1. Full-range anti-corrosion cleaning mediaHydrocarbon cleaning machines adopt chlorine-free neutral solvents that cause no corrosion to aluminum. A customized neutral aluminum corrosion inhibitor cleaner (pH 6.8~7.8, phosphorus-free, chlorine-free and silicate-free) is matched for aqueous cleaning lines, preventing pitting corrosion, blackening and luster loss of aluminum parts even after long-term immersion at varying temperatures.

2. Complete elimination of water stains and white bloom defects

• The vacuum hydrocarbon solution involves zero water contact throughout the process with low-temperature vacuum drying, completely erasing water marks and white speckles;

• The aqueous line is equipped with three-stage high-purity countercurrent pure water rinsing and high-power air knives for water removal, paired with closed-loop low-temperature drying at 50~55°C. It avoids whitening caused by residual calcium & magnesium ions and high-temperature oxidation, and guarantees adhesion performance for welding, spraying and bonding processes.

3. Low-damage ultrasonic process designDual-frequency ultrasonic system (28kHz for rough cleaning + 40kHz for fine cleaning) comes as standard, with power density strictly controlled below 0.4W/cm². Gentle cavitation removes contaminants without damaging the native oxide film on aluminum, so exterior stamped parts will not suffer surface hazing or pitting after cleaning.

II. Ultra-high cleaning cleanliness to meet strict ISO 16232 standards for new energy vehicles

1. Deep all-round decontamination without dead zonesVacuum hydrocarbon technology relies on negative pressure to penetrate micro gaps as narrow as 0.03mm. The 5-axis CNC fixed-point high-pressure spraying precisely scours blind holes, flow channels and reinforcing rib interlayers, thoroughly removing stubborn drawing oil, high-viscosity stamping grease, embedded aluminum powder and micro stamping burrs.

2. Stable compliance with new energy vehicle technical indicatorsAfter cleaning, residual oil ≤50mg/㎡ and residual particles ≤300μm with no free aluminum powder left. It avoids mass quality failures such as internal battery short circuits, motor abnormal noise, welding pores and electrophoresis pitting, and can directly pass OEM cleanliness inspection and audit.

3. Integrated cleaning and deburringFor complex perforated aluminum parts with flow channels, the CNC composite cleaning solution removes aluminum scraps and micro burrs in gaps via high-pressure water jet, eliminating a separate deburring process and shortening the overall production line workflow.

III. Three flexible process options covering all types of aluminum stamped parts

1. Premium precision new energy parts: BK-CH series vacuum hydrocarbon cleaning equipmentZero wastewater discharge and low VOC emissions. Ideal for battery aluminum casings, water cooling plates and exterior body panels. It can connect with fully automatic stamping lines and MES intelligent production lines, meeting green factory environmental standards.

2. Mass-produced aluminum bodies & battery trays: BK-WL through-type aqueous cleaning lineModerate investment cost with high production capacity, reaching a maximum daily output of 18,000 pieces. Chromium-free silane passivation is optional, suitable for mass pre-treatment lines for phosphating and spraying.

3. Complex perforated aluminum parts with flow channels: BK-CNC high-pressure spray composite solution5-axis CNC fixed-point cleaning specifically addresses the problem of aluminum scraps trapped in cross holes of motor housings and water cooling plates, fulfilling dual demands of degreasing and debris removal.

IV. Long-term cost reduction with drastically lower consumable and operation & maintenance costs

1. Efficient recycling and reuse of cleaning fluids

• Vacuum distillation regeneration for hydrocarbon equipment achieves a solvent recovery rate of 98%, requiring minimal replenishment of new solvent;

• Aqueous lines are equipped with magnetic separation and paper tape filtration systems to automatically recover stamping oil and intercept aluminum powder, extending the service life of tank liquid by 70% and sharply reducing the frequency of cleaning agent replacement.

2. Fully automatic unattended operationStandard robotic loading & unloading, built-in storage of intelligent PLC programs to switch cleaning parameters for different aluminum parts with one click, supporting remote monitoring and output statistics to cut labor costs for on-site supervision.

3. Less rework and scrapped productsIt eliminates mass scrapping caused by poor welding and coating peeling stemming from aluminum corrosion, water stains, residual oil and particles, lowering rework and material loss costs from the source.

V. Durable equipment with exclusive hardware configurations for aluminum cleaning

1. 316L stainless steel for all media-contact componentsTanks, pipelines and ultrasonic vibratory plates are free of ordinary carbon steel, preventing galvanic corrosion from contact between iron and aluminum and extending the service life of equipment.

2. Custom hollow stamping toolingSuspended hollow material baskets and curved surface support fixtures prevent water accumulation and coverage from stacked workpieces for 360° full cleaning, while protecting stamped exterior surfaces from scratches.

3. Intelligent online monitoring and protectionAqueous lines monitor pH value and temperature in real time, and automatically alarm and shut down the equipment in case of overheating or unbalanced pH value to avoid batch scrapping of corroded aluminum parts.

VI. Environmentally compliant to satisfy green production requirements of OEMs

1. The vacuum hydrocarbon solution generates nearly zero wastewater, with VOC emissions far below national environmental limits, requiring no complex wastewater treatment equipment;

2. The aqueous cleaning agent is phosphorus-free and chlorine-free, and can meet discharge standards with simple oil-water separation treatment, facilitating environmental impact assessment and green factory audits;

3. Closed solvent circulation eliminates volatile odors and improves the workshop working environment.

VII. One-stop complete supporting solutions and comprehensive after-sales service

1. Matched dedicated aluminum cleaning media, filter consumables and passivation chemicals with complete process matching, requiring no self-matching of agents by customers;

2. A complete cleanliness testing scheme is provided upon delivery, which can generate test reports compliant with ISO 16232 to pass OEM incoming audits;

3. Production line transformation and interconnection are supported, enabling direct connection with automatic stamping, laser welding, spraying and assembly lines to realize full-line intelligent integration.
