Gooseneck repair requires technology, it is the core component of the hot chamber die casting machine.
Responsible for transporting the molten metal from the furnace to the mold.
And its design directly affects the quality, production efficiency and equipment life of the die casting.
Gooseneck structure
It is made of high-quality cast steel or forged steel, which has the characteristics of high temperature resistance and corrosion resistance.
Design
Plugless feeding channel: reduce the agitation of molten metal and improve the qualification rate of castings.
High concentricity
Ensure the concentricity between the pot and the core during long-term use, and avoid leakage or wear caused by eccentricity.
Life span
Under normal operation, it can reach 1 million molds, and some cases exceed 2 million molds.
Analysis of common fault types and causes
Gooseneck spillage
Wear of the cone surface of the kettle or mismatch of the taper of the nozzle body.
Wrong installation method (e.g., loose at high temperature due to unheated cone).
Impact
Leakage of molten metal leads to equipment contamination, safety hazards, and material waste.
Plugged nozzle (plug)
Insufficient temperature causes the metal to solidify.
Performance: Injection interruption, need to stop for cleaning or heating and dredging.
Flying material (molten metal splashing)
The nozzle body and the cone surface of the gooseneck pot are not well matched.
Alternatively, the mold inlet is misaligned from the center of the nozzle, or the cone hole is not preheated during installation.
It is also possible that internal corrosion or wear is caused by long-term high-temperature oxidation, metal erosion, or impurity corrosion.
Focus on areas of expertise
Haichen focuses on the production and maintenance of die-casting machine accessories, and clearly mentions that its products cover key components.
Such as material pots (gooseneck), nozzle heads, and nozzle bodies, which are suitable for well-known die-casting machine brands at home and abroad.
Material process: using high-quality imported hot work die steel and special casting process, heat treatment to remove mechanical stress.
To ensure that the product is resistant to high temperature, wear and tear, no porosity shrinkage.
Application scenario
Specially designed for hot chamber die-casting machine, suitable for a variety of models, to meet the needs of industrial-grade use.
