Core Overview

Sinobakr’s camshaft cleaning solution adopts a closed-loop process of environmental hydrocarbon / modified alcohol solvent + ultrasonic cleaning + vacuum drying. It solves the pain points of traditional water-based cleaning such as easy rusting, incomplete degreasing and residual particles in oil passages, achieving non-corrosion, zero sewage discharge, high cleanliness and recyclable solvent reuse for mass production.

1. Core Cleaning Difficulties

• Oil dirt & carbon deposits: Thermally cured sludge, carbon deposits and varnish on camshaft surfaces, cam lobes, journal surfaces and oil passages.

• Micro-particle residue: Metal scraps and grinding powder left in machined oil holes, inclined oil passages and threaded holes, which easily cause shaft scuffing and abnormal noise.

• Rust risk: Residues of water-based cleaning agents easily lead to rust on cast iron/steel camshafts and damage surface roughness.

• Precision surface protection: Cam lobes and journals are high-frequency friction surfaces; the cleaning process must avoid scratches, corrosion and material embrittlement.

2. Recommended Standard Buck Equipment

BK-5144RYH 5-Tank Full-Automatic Hydrocarbon Cleaning Machine (First choice for mass production)

Process: Emulsification → Vacuum ultrasonic cleaning → Spray rinsing → Vapor degreasing → Vacuum dryingAdvantages: Anti-oxidation under vacuum; ultrasonic deep cleaning of blind holes; solvent distillation recycling (recovery rate ≥95%); zero sewage discharge.

BK-600RYH Single-Station Hydrocarbon Cleaning Machine (Small batch / maintenance workshop)

Process: Spraying → Ultrasonic cleaning → Rinsing → Air cutting → Vacuum drying, with reversible/swing cleaning function.Advantages: Small footprint, low cost, high flexibility; suitable for maintenance workshops and small-batch production.

3. Standard Camshaft Cleaning Process (Hydrocarbon Solvent)

1. Pre-treatment (Manual / Automatic)Remove bulk iron scraps and sediment on the camshaft; block key oil holes to prevent internal contamination infiltration.

2. Vacuum Ultrasonic Main Cleaning (50–65℃, 5–10 min)Hydrocarbon solvent dissolves sludge and carbon deposits; ultrasonic wave (28–40 kHz) strips contaminants on surfaces and inside oil passages.Power density: 0.5–0.6 W/cm² to avoid damaging precision surfaces by excessive cavitation.

3. Spray Rinsing (2–3 min)High-pressure flushing (0.4–0.6 MPa) with hydrocarbon solvent to replace residual contaminants in blind holes.

4. Vacuum Ultrasonic Fine Cleaning (3–5 min)Low-power ultrasonic + fresh solvent to remove micron-scale residual particles and meet cleanliness standards.

5. Vapor Degreasing (1–2 min)Hydrocarbon vapor covers the surface to dissolve residual oil stains and improve surface uniformity.

6. Vacuum Drying (80–120℃, -0.09 MPa, 5–8 min)Thorough drying in oxygen-free environment; no rust, no water marks and no solvent residue.

7. Inspection & Anti-rust ProtectionEndoscope inspection of oil passages; compressed air purging; vacuum packaging or anti-rust oil coating.

4. Core Advantages of Buck Solution

• Material Compatibility: Hydrocarbon/modified alcohol solvents are chlorine-free, sulfur-free and moisture-free; no corrosion to camshafts, protecting metallographic structure and hardness.

• Qualified Cleanliness: Stably complies with ISO 16232 and GB/T 3821 standards; no visible grease in oil passages, residual particles ≤1 μm.

• Eco-friendly: Zero sewage discharge, low VOC emission, recyclable solvent, reducing hazardous waste disposal costs.

• High Efficiency & Cost-effective: Fully automatic process; single batch processing time ≤30 min; solvent recovery rate ≥95%, with lower long-term cost than water-based & anti-rust processes.

5. Application Scenarios & Notes

Applicable Scenarios

Precautions

• Check the camshaft for cracks and severe wear before cleaning;

• Solvent flash point ≥60℃; equipped with explosion-proof and fire suppression system;

• Complete anti-rust treatment or assembly within 4 hours after drying.
