Brand: Sinobakr. Positioning: CNC high-pressure water jet deburring & cleaning integrated machine dedicated to new-energy automotive die-cast housings, an import-substitution precision cleaning equipment complying with VDA19 cleanliness requirements.

1. Product Introduction (Short Version – for Cover / Opening Page)

The Sinobakr CNC high-pressure cleaning machine adopts multi-axis servo CNC high-pressure water jet technology, developed exclusively for aluminum alloy die-cast housings. It performs targeted inner-cavity deburring, aluminum swarf flushing, cutting oil removal, rinsing and hot-air drying in a single clamping operation. The system accurately targets hidden flow passages including intersecting cross holes, blind holes, threaded holes, water and oil channels. It addresses the limitations of ultrasonic cleaning, conventional spraying and brush cleaning, which fail to remove residues inside inner cavities. It consistently meets the VDA19 automotive technical cleanliness specification. Widely deployed in mass-production lines for new-energy three-electric housings, gearbox housings, electronic control housings and reducer housings, it supports automatic production line connection and MES data traceability.

2. Core Advantages (Bullet Points for PPT)

1. Targeted inner-cavity cleaning, no dead zonesEquipped with 3/5-axis CNC linkage and CNC indexing rotary table, the retractable and rotatable water nozzle follows programmable motion paths. Multiple nozzle modes including 45° angled spray, 90° side spray and straight spray reach intersecting cross holes, deep blind holes and interlayer oil passages to remove burrs at intersections and embedded aluminum swarf, covering areas inaccessible to conventional cleaning methods.

2. Non-damaging physical process, no harm to aluminum workpiecesPure high-pressure water jet, no abrasives and no tool contact. Cold jet impact causes no thermal deformation, surface scratches or dimensional and geometric tolerance changes. Suitable for soft die-cast aluminum parts; no secondary burrs or dust contamination will be generated.

3. Combined processes for shorter cycle timeA single unit integrates deburring, cleaning, rinsing, oil-water separation and hot-air drying. All processes are finished in one clamping, eliminating repeated workpiece transfer and rework, greatly cutting labor costs and supporting high-volume continuous production.

4. Consistent cleaning performance, stable VDA19 complianceVariable-frequency high-pressure system with locked pressure, feed speed and jet duration in programs. Multi-stage filtration plus magnetic swarf removal stabilizes water quality, minimizing batch-to-batch variation of particle residues. Particle indicators are reliably controlled to smoothly pass OEM cleanliness sampling audits.

5. Intelligent traceability for automotive quality systems10-inch industrial touchscreen; stores over 100 sets of workpiece programs. Compatible with MES connection, cleaning log storage, parameter recording and remote maintenance, satisfying traceability requirements of IATF16949.

6. Energy-saving water circulation, safe enclosed designThree-stage precision filtration + magnetic aluminum swarf removal + built-in oil-water separator. Up to 95% of cleaning water is recycled for low water consumption. Fully enclosed soundproof cabin, pressure overload protection, safety interlocks and corrosion-resistant water circuits ensure a clean workshop environment with low noise.

7. Flexible non-standard customizationTravel range, fixtures and nozzle groups can be customized. Optional modules include robotic automatic loading & unloading, vacuum drying and low-pressure rinsing units, compatible with motor housings, ECU housings and reducer housings of various sizes.

3. Applicable Workpieces

5. Standard Process Flow

Workpiece clamping and positioning → High-pressure targeted water jet deburring & aluminum swarf flushing (focus on cross holes & blind holes) → Low-pressure rinsing → Contaminant separation via circulating filtration → Hot-air drying → Unloading. Fully automatic enclosed operation.

6. Comparison with Traditional Cleaning Solutions

• Ultrasonic cleaning: Only effective for surfaces and shallow holes. Hard to remove aluminum swarf and intersection burrs in deep cross holes; low VDA19 pass rate.

• Brush cleaning: Only for outer surfaces. Cannot reach deep holes; bristles may fall off and cause secondary contamination; poor consistency.

• Manual high-pressure gun: Heavily operator-dependent, prone to missed cleaning, low efficiency and unstable cleanliness; high labor cost.

• Sinobakr CNC high-pressure water jet: CNC trajectory targeted impact, full coverage of inner dead zones, fixed programs, stable batch quality, meets OEM VDA19 requirements.

7. Common Customer Pain Points & Sales Responses

Q: We repeatedly rework due to aluminum swarf and burrs inside intersecting oil passages, and frequently fail cleanliness sampling. A: Conventional cleaning only flushes outer surfaces. Burrs at intersections and embedded swarf are trapped inside channels. The Sinobakr CNC water nozzle is programmed according to housing drawings to aim at each group of cross holes, stripping burrs from the root and flushing out debris for stable, controllable results.

Q: Aluminum parts are easily scratched or deformed. Will high-pressure water damage the workpiece? A: High-pressure water is a flexible non-contact process with no physical tool contact. Pressure, jet distance and angle are programmable and validated during trial production. It will not scratch aluminum surfaces or cause deformation.

Q: Can this equipment connect to automatic production lines? A: It supports robot loading/unloading and roller conveyor integration. Cleaning data can be uploaded to MES. The cleaning pressure, duration and program version of every single workpiece are recorded for OEM traceability.
