Application of sprayer

The main functions of the sprayer in die casting are lubrication of the mold, cooling, and demolding. Types include automatic, servo, two-axis, internal spraying, etc.

The technical features include precise control, programmability and integration. It is used in high-volume applications such as automotive parts, copper alloy die-casting, etc. It should be noted that different models are suitable for different tonnages and materials. The servo spraying machine is energy-efficient and efficient, and internal spraying reduces waste.

When selecting a sprayer for die casting, focus on the following critical criteria and standards to ensure compatibility with your production needs, while avoiding reliance on specific model examples:


Key Selection Criteria

Application of sprayer for die casting machine
  1. Nozzle & Spray Performance
    • Flow Rate/Pressure Compatibility: Choose a sprayer with adjustable flow rate (e.g., 5–30 L/min) and pressure range (0.3–1.5 MPa) to match mold size and release agent requirements.
    • Atomization Precision: Prioritize sprayers with atomized droplet sizes ≤50μm to minimize release agent waste and ensure uniform coating.
    • High-Temperature Resistance: Opt for nozzles made of materials (e.g., 316L stainless steel, ceramic-coated) that withstand temperatures ≥200°C for die casting environments.
  2. Automation Integration
    • Robot Compatibility: Ensure compatibility with industrial robots (e.g., KUKA, Fanuc) via communication protocols (e.g., Profinet, EtherCAT) for dynamic spray path programming.
    • Closed-Loop Control: Select sprayers with real-time feedback systems for flow rate and pressure to maintain process consistency.
  3. Functional Flexibility
    • Multi-Mode Spraying: Support for point, line, and surface spraying modes to adapt to complex mold geometries (e.g., deep cavities, narrow gaps).
    • Quick-Change Systems: Modular gun designs enabling multi-nozzle swaps within 10 minutes for faster mold changeovers.
  4. Cost & Energy Efficiency
    • Energy-Saving Design: Prioritize servo-driven sprayers, which reduce energy consumption by 30%+ compared to pneumatic systems (target power use ≤3 kW/h).
    • Release Agent Efficiency: Use high-precision metering pumps (error ≤±2%) to minimize agent consumption (target ≤50 ml per cycle).
  5. Compliance & Safety
    • Adhere to standards like China’s JB/T 12284 or Europe’s EN 12981 for safety and performance, including explosion-proof and pressure resistance certifications.

Alternative Solutions

  • Customization: Share mold drawings and process parameters (e.g., spray area, cycle time) with suppliers to develop tailored solutions.
  • Brand Recommendations:
    • European Brands: Focus on energy-efficient servo-driven sprayers (e.g., Striko, Dürr).
    • Japanese/Korean Brands: Prioritize high-precision atomization control (e.g., Yushin, Toyo).
    • Domestic Alternatives: Consider CE/UL-certified manufacturers (e.g., Haichen,LK Group, Yizumi).

Validation Steps

Aluminum pressure die casting alloy
  1. On-Site Testing: Request sample machines to verify spray coverage and residue levels (target residue ≤0.1 mg/cm²).
  2. Performance Metrics:
    • Measure release agent consumption per cycle (target ≤50 ml/cycle).
    • Evaluate equipment reliability (target MTBF ≥5,000 hours).

By aligning with these criteria, you can select a sprayer that optimizes efficiency, reduces costs, and integrates seamlessly into automated die casting lines.

1. Role and Configuration of Sprayers

Haichen’s sprayers are explicitly listed as part of its die-casting equipment portfolio. They work in tandem with core components (e.g., die-casting machines, molds, and extractors) to form a complete production line. Key functions include:

  • Lubrication: Ensures smooth mold operation and prevents sticking during demolding.
  • Temperature Control: Regulates mold surface temperature to minimize thermal stress and defects.
  • Extended Mold Lifespan: Reduces wear and tear by maintaining consistent lubrication.

2. Nozzle Types and Optimization

Haichen offers customizable nozzle designs tailored to specific production requirements:

Types of spray nozzles
  • Y-Type Nozzles: Ideal for complex mold cavities, enabling multi-directional spray coverage for uniform coating.
  • Pinch Nozzles: Use a “pinching” mechanism to control flow rate, minimizing overspray and improving precision.
  • High-Pressure Nozzles: Engineered for high-accuracy applications, paired with robust pressure control systems.
    Nozzle selection depends on factors like alloy type, mold geometry, and quality standards (e.g., high-pressure nozzles for precision automotive parts).

3. Technology Integration and Quality Assurance
