RSB-103C Low-Foam Anti-Rust Metal Cleaner – Automotive Camshaft Mass Production Application Case

1. Problem (Core Production Pain Points of Automotive Camshaft Machining Workshops)

1. Severe foaming fails automatic high-pressure spray lines: Conventional high-foam cleaners overflow spray chambers, block nozzles, cause uneven flushing, and force frequent production line shutdowns for foam removal, seriously reducing continuous output.
2. Flash rust occurs instantly after cleaning: Most degreasers lack built-in rust inhibitors. Machined steel camshafts develop yellow flash rust within minutes after water-based washing, triggering high rejection rates before assembly or grinding.
3. Residual cutting fluid & metal debris trapped in cam lobes and oil grooves: Camshafts feature complex curved cam profiles, narrow oil passages and thread blind holes. Ordinary cleaners cannot fully strip emulsified cutting fluid, fine iron powder and grinding dust, leading to engine valve jamming after assembly.
4. Dual separate processes raise labor & time costs: Factories use one cleaner for degreasing and a separate anti-rust oil tank for inter-process protection, adding extra handling, drying and dipping steps, lengthening takt time.
5. Harmful restricted substances bring export compliance risks: Many mainstream cleaners contain sodium nitrite, chromate and heavy metals, failing automotive OEM environmental audits and RoHS testing.
6. Short bath service life & frequent liquid replacement: Common degreasers mix oil rapidly and lose detergency quickly, increasing chemical procurement and hazardous waste disposal expenses.

2.3 Physical & Chemical Technical Parameters (5% aqueous solution, 25℃ test)

2.4 Product Safety Attributes

3. Soil (All Contaminants Removed on Automotive Camshafts in Single Cycle)

1. Machining fluid pollutants: Emulsified water-soluble cutting fluid, heavy grinding oil, forged anti-rust base oil residues
2. Solid particulate dirt: Fine iron filings, grinding abrasive dust, metal powder trapped in cam gaps and blind oil passages
3. Surface contamination: Operator fingerprint sweat, workshop floating dust, inorganic mineral water stains
4. Aged mixed dirt accumulated during multi-step forging, turning and grinding processes

4. Cleaning Process (Standard Automatic Spray Production Line Flow for Camshafts)

4.1 Supported Cleaning Modes

1. Through-type medium/high pressure automatic spray washing (core mass production process for camshafts)
2. Hot bubbling soaking tank (small batch offline re-cleaning)
3. Ultrasonic cleaning (precision micro blind hole deep cleaning)
4. Manual scrubbing for localized heavy oil spots

4.2 Standard Process Technical Parameters

• Dilution Ratio: 5% ~ 10% RSB-103C aqueous solution
• Operating Temperature: 50 ~ 70℃ (optimal degreasing & anti-rust performance)
• Standard Cleaning Duration: 5 ~ 10 minutes continuous spray circulation
• Special Tip: Shake the barrel evenly before tank preparation

4.3 Complete Post-Cleaning Workflow

4.4 Daily Bath & Operation Management Rules

1. Place camshafts vertically on cleaning racks without overlapping to avoid blind cleaning zones on cam lobes;
2. Regularly replenish RSB-103C stock liquid when oil separation and detergency decline; fully replace tank liquid if performance cannot recover after supplementation;
3. The spray workshop must maintain mechanical ventilation; operators wear full work uniforms and acid-base resistant latex gloves;
4. Seal barrels tightly and store separately from strong acids and strong oxidants, avoid sunlight and high-temperature environments.

5. Test Standard (Automotive OEM Cleanliness, Anti-Rust & Safety Criteria)

1. Physical Index Standard: Fully meet appearance, specific gravity and pH specifications under laboratory testing; ultra-low foam to prevent spray nozzle blockage and overflow at medium/high pressure.
2. Metal Corrosion Protection Standard: Zero etching or discoloration on carbon steel camshafts and aluminum auxiliary parts after full cleaning cycle; no surface matte or pitting defects.
3. Inter-Process Anti-Rust Standard: Cleaned unrinsed camshaft surfaces form a uniform thin organic inhibitor film, effectively resisting flash rust during 72-hour indoor temporary storage.
4. Degreasing Cleanliness Standard: No visible cutting fluid residue, metal powder or oil film on cam lobes, journals and internal oil passages after spray washing, meets automotive engine part cleanliness inspection standards.
5. Environmental Compliance Standard: Nitrite-free, chromate-free and heavy metal-free formula, fully compliant with auto factory wastewater discharge and RoHS export regulations.
6. Production Safety Standard: Non-flammable water-based liquid, low irritating odor, reduces occupational skin damage risks for long-shift workshop workers.

6. Result (On-Site Camshaft Production Line Test Outcomes)

1. Zero foam interference for automatic spray lines: Ultra-low foam design eliminates nozzle clogging and foam overflow, realizing uninterrupted 24-hour continuous camshaft mass production and lifting line output by 35%+.
2. One-step degreasing + inter-process anti-rust integration: Eliminates separate anti-rust oil dipping procedures, cuts single camshaft processing time and reduces auxiliary labor input.
3. Complete removal of hidden blind-hole contaminants: Strong penetration flushes cutting fluid and metal powder out of narrow cam oil passages, dropping engine assembly failure reject rate caused by residual dirt by over 90%.
4. Stable long bath service life: Excellent oil separation performance delays liquid deterioration, reducing chemical replacement frequency and cutting hazardous waste disposal costs by 40%.
5. Wide dual-metal compatibility: Safely cleans both forged steel camshafts and matched aluminum engine components, simplifying factory chemical inventory.
6. No flash rust during WIP storage: Built-in organic rust inhibitor prevents yellow oxidation spots without secondary rinsing, eliminating rework for rusted camshaft blanks.
7. Green compliant formula eliminates export risks: Free of all restricted toxic components, smoothly passes automotive OEM incoming environmental audits and overseas export inspections.

7. Buyer Takeaway (Core Commercial Value for Automotive Camshaft Manufacturers)

1. Custom low-foam formula specially built for automatic camshaft spray lines, solving the most troublesome foam blockage pain point of traditional cleaners.
2. Cut multi-process labor & time costs: Combine degreasing and inter-process rust prevention into one single station, streamline production layout and shorten production takt.
3. Dramatically reduce camshaft scrap losses: Anti-rust protection eliminates flash rust waste; thorough deep cleaning avoids post-assembly engine faults and customer compensation penalties.
4. Lower long-term chemical & waste treatment expenditure: Long-lasting tank liquid reduces monthly raw material procurement and hazardous waste handling fees.
