Haichen long-life hot chamber zinc alloy die casting machine accessories gooseneck spare parts
| Die casting machine gooseneck |
The gooseneck tube is the core component of the hot chamber die casting machine (also known as the gooseneck die casting machine), which is mainly used in the die casting process of low melting point metals (such as zinc, magnesium, lead alloys and some aluminum alloys). |
1. Role of the Gooseneck in Die Casting Machines
The gooseneck is a critical metal delivery component in die casting machines, responsible for channeling molten metal from the injection system into the mold cavity. Its design directly impacts metal flow stability, filling efficiency, and final casting quality.
2. Key Gooseneck Types by Haichen
Haichen offers versatile gooseneck designs, including:
- Straight Gooseneck: Simple linear flow path, ideal for molds aligned directly with the injection system. Advantages include easy maintenance and smooth metal flow, but limited adaptability for complex molds.
- Adjustable Gooseneck: Features angle and length adjustments for flexibility across molds or multi-mold configurations. Reduces replacement frequency and maintenance costs.
3. Gooseneck Features in Hot-Chamber Machines
- Material & Heat Resistance: Made from high-heat-resistant materials (e.g., premium cast or forged steel) to withstand prolonged immersion in molten metals (e.g., zinc, lead alloys), ensuring mechanical strength and corrosion resistance.
- Integrated Design: In hot-chamber machines, the gooseneck is integrated with the injection cylinder. Molten metal is forced into the mold via piston action, enabling rapid filling (e.g., single-shot zinc alloy capacity up to 1.6 kg) for thin-walled, high-precision parts.
- Replaceability: Designed as a replaceable component to extend machine lifespan under continuous high-temperature operation.
4. Hot-Chamber vs. Cold-Chamber Machines
- Material Compatibility: Haichen's HCH-series hot-chamber machines are optimized for low-melting-point alloys (zinc, lead), while HCD-series cold-chamber machines handle aluminum/magnesium. Goosenecks are exclusive to hot-chamber systems; cold-chamber machines use separate injection cylinders.
- Process Efficiency: Hot-chamber goosenecks are submerged in molten metal, minimizing oxidation and heat loss for high-volume production. Cold-chamber machines rely on ladling, offering flexibility but slower cycles.
5. Haichen Gooseneck Advantages
- Smart Control Integration: Combines with servo-hydraulic systems for precise pressure and speed adjustments (e.g., cold-chamber injection speeds up to 8 m/s).
- Modular Design: Adjustable goosenecks enable customization for multi-cavity molds (e.g., 90-ton machines producing 4-cavity zinc alloy door handles).
- Sustainability: Optimized flow paths reduce turbulence, lowering energy consumption and material waste, aligning with Haichen's eco-friendly principles.
6. Applications
- Zinc Alloy Components: Example: 90-ton hot-chamber machines efficiently produce zinc door handles and lock cores, compatible with post-processing (electroplating, polishing) for automotive and hardware industries.
- Complex Castings: Adjustable "swan-neck" designs enhance metal flow in multi-angle molds, reducing porosity and cold-shut defects.
Haichen's goosenecks excel in durability, adaptability, and high-efficiency metal delivery, particularly in hot-chamber machines. Their modularity and heat-resistant materials support diverse production needs, while smart controls ensure precision and longevity. For high-speed, high-volume zinc/lead alloy casting, Haichen's hot-chamber systems with advanced goosenecks are an optimal choice.
