Automatic Core Shooter
The automatic core shooter Coated Sand Core Shooting Machine uses coated sand as the raw material and operates on the hot core box principle to produce coated sand molds. The core shooting process uses phenolic resin sand, which results in high production efficiency, precise dimensions, smooth surfaces, and the ability to produce castings with complex inner cavities.
Technical Specifications and Key Advantages of ZH650 Double-Head Core-Shooting Machine
I. Equipment Overview
| Item | Specification/Configuration | Comparison with Traditional Equipment |
|---|---|---|
| Application | Shell molds & shell cores production | Single-head machines limited to one mold type |
| Control System | PLC programmable control (supports recipe storage/recall) | Manual/semi-auto adjustment, unstable parameters |
| Cycle Time | 30–240 sec (mold size-dependent, ±5% adjustable) | Fixed cycle, low compatibility |
| Sand Shooting Pressure | 0.4–0.7 MPa (high-pressure airflow injection) | Typically ≤0.5 MPa, uneven filling |
| Mold Temperature Control | Dual-mode heating (electric/gas) with closed-loop control (180–240°C ±5°C) | Single heating mode, ±15°C accuracy |
II. Innovative Design Highlights
- Modular Water-Cooled Shooter
- Integrated Design: Built-in water circulation keeps nozzle temperature ≤50°C, preventing resin pre-curing.
- Quick-Split Modification: Split into dual independent shooters in ≤5 mins, compatible with core boxes (Φ50–300 mm).
- Cost Efficiency: Retrofit cost reduced by 70%, compatibility expanded by 300% (supports complex/miniature cores).
- Smart Process Management
- Digital presets for shooting time, pressure holding, and heating curves, improving mold-change efficiency by 90%.
- Self-diagnostic system (covers 12 common faults, e.g., sand clogging, temperature deviations).
III. Shell Core Production Workflow (Phenolic Resin Sand Example)
| Step | Parameters | Mechanism |
|---|---|---|
| 1. Core Box Preheating | Initial temp: 200–220°C (electric mode) | Ensures rapid resin melting on core box surface to form a bonding layer. |
| 2. Sand Injection | Pressure: 0.6 MPa, duration: 5–15 sec | High-pressure airflow ensures ≥98% filling rate (no dead zones). |
| 3. Shell Formation | Static heating: 30–90 sec (5–12 mm thickness) | Resin near walls carbonizes, bonding sand into dense shell; excess sand automatically discharged (recovery rate >85%). |
| 4. Curing & Cooling | Air/water cooling to ≤80°C | Prevents thermal deformation, reduces demolding time to <20 sec. |
| 5. Automatic Ejection | Hydraulic ejector precision: ±0.1 mm | Damage-free demolding, surface roughness Ra ≤6.3 μm (no post-processing). |
IV. Typical Applications & Cost-Benefit Analysis
| Industry | Applications | Efficiency Gain | Cost Savings |
|---|---|---|---|
| Automotive | Engine water jacket cores, turbo housings | 1,200–1,500 pcs/shift (+40% YoY) | 25% less sand, 18% lower energy |
| Pump/Valve | Complex-flow valve cores, pressure-resistant pump shells | Yield rate: 88% → 96% | 70% fewer labor dependencies |
| Aerospace | Thin-wall turbine blades, superalloy cores | Cycle time: 45 sec (vs. 180 sec) | 90% less post-processing time |
V. Technical Q&A (Common Issues & Solutions)
- Issue 1: Uneven shell thickness due to inconsistent sand injection
Solution: Calibrate shooter-core box alignment (tolerance <0.05 mm); add real-time sand moisture monitoring (target: 3.2–3.8%). - Issue 2: Demolding adhesion
Solution: Apply nano-coated release agent (1 spray/10k cycles); install vibration-assisted ejection (50 Hz frequency).

Resin Sand Molding Production Line
Foundry Machinery: China Resin Sand Reclamation Casting Machines
The resin sand molding and core-making process utilizes sand mixed with a specific amount of resin glue, which hardens naturally within a certain timeframe at room temperature. This self-hardening sand technology is widely adopted in modern foundries, with commonly used types including furan resin sand, ester-hardening alkaline phenolic resin sand, and pep-set resin sand.
Key Features:
- Self-Hardening Technology: The molding and core sand harden naturally at room temperature, with the hardening rate and final hardness influenced by ambient temperature and humidity.
- Versatile Applications: Ideal for single-piece production, small batch runs, and various medium to large-scale castings.
- Industry Usage: Widely employed in industries such as general machinery, heavy equipment, shipbuilding, locomotive manufacturing, and motorcycles.
The resin sand molding process offers excellent adaptability and is well-suited for creating high-quality molds and cores for complex castings.
