HAICHEN is equipped with high-temperature zinc removal cleaning equipment, hot-pressing disassembly and assembly tooling, and non-destructive testing equipment for gooseneck repair.

In hot chamber die casting machines, gooseneck pots (or goosenecks) are the key components connecting the furnace and the mold.

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.

First of all, Haichen provides gooseneck resleeving service for zinc hot chamber die casting machine. Furthermore, Haichen carries out complete overhaul work including acid cleaning, old sleeve extraction, new liner pressing, taper lapping and heating hole repair.

In addition, Haichen fixes common equipment faults such as leakage, metal clogging, unstable injection pressure and nozzle splashing.

Meanwhile, Haichen runs magnaflux crack inspection on every finished part before delivery to stop thermal leakage risks.

Finally, Haichen conducts honing treatment on all repaired goosenecks so these parts hold the same precision as original factory components.

Gooseneck Structure

• Premium Raw Material Selection
• Optimized Plugless Feeding Channel
• Strict High Concentricity Control
• Long Stable Service Lifespan

Premium Raw Material Selection

First of all, Haichen designs robust gooseneck structures for zinc hot chamber die casting production. Furthermore, Haichen selects premium cast steel and forged steel to build every gooseneck, and these raw materials deliver strong resistance against high temperature and molten metal corrosion.

Optimized Plugless Feeding Channel

In addition, Haichen equips each gooseneck with a plugless feeding channel; this channel lessens unnecessary agitation inside molten metal and lifts the overall qualification rate of finished castings.

Strict High Concentricity Control

Meanwhile, Haichen strictly controls high concentricity standards during the whole manufacturing process.

Moreover, Haichen’s precise production ensures steady concentricity between the gooseneck pot and inner core over long continuous operation, and effectively prevents leakage and abnormal wear triggered by eccentric deviation.

Long Stable Service Lifespan

Besides that, Haichen’s well-crafted goosenecks own outstanding service life performance.

Finally, Haichen’s standard gooseneck units hit a service life of 1 million molds under regular operating conditions, and many well-maintained units even surpass a lifespan of 2 million molds.

Analysis of gooseneck common fault types and causes

• Gooseneck spillage
• Impact
• Plugged nozzle

Gooseneck spillage

Wear of the cone surface of the kettle or mismatch of the taper of the nozzle body.

Besides,wrong installation method (e.g., loose at high temperature due to unheated cone).

Impact

Actually,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.

Gooseneck flying material

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.
