Advantages of Hot Chamber Zinc Die Casting Service

Zinc die casting is a hot Chamber die casting manufacturing process. Hot chamber zinc die casting uses high pressure to pump molten zinc into a mold to create complicated parts and components with extreme precision and accuracy. From low-volume production to mass production, hot chamber zinc die casting is a good manufacturing process.

  • 4
    Lower Tooling Cost

    Zinc dies casting can survive up to ten times longer than aluminium die casting dies and around five times longer than magnesium die casting dies due to their low melting temperature. This results in fewer repairs, less downtime, and more components produced over the tool's lifetime.

  • 1
    High Durable Quality Parts

    Zinc is known for its inherent strength and hardness, making it suitable for producing durable parts. The die casting process enhances these properties further by creating a dense and uniform structure. Zinc die-cast parts can withstand high loads, vibrations, and impacts, making them suitable for demanding applications.

  • 2
    Excellent Mechanical and Physical Properties

    Zinc is a highly machinable material, allowing for easy post-casting operations such as drilling, tapping, and milling. This enables the production of intricate features and facilitates secondary machining processes, if required, to achieve specific part requirements.

  • 6
    Faster Production Time

    The combination of high casting speed, quick solidification, minimal post-casting operations, simplicity of the process, long tooling lifespan, scalability, and efficient material utilization makes zinc die casting a fast and efficient production method, meeting the demands of industries that require rapid turnaround times and high production volumes.

Our Zinc Alloy Die-Casting Process Workflow

The hot chamber zinc die casting process is a manufacturing technology that uses molten zinc to make high-precision metal parts. This process's workflow typically involves the following steps:

  • 1
    Mold Preparation

    The first step is to get the mold ready for the die casting procedure. Molds are usually constructed of two sections that are fastened together to produce a cavity.

  • 2
    Molten Zinc Injection

    After the mold has been prepared, molten zinc is injected into the cavity. This is accomplished by utilizing a piston to drive molten metal through a nozzle and into the cavity.

  • 3
    Cooling and Solidification

    The molten zinc immediately cools and hardens after being injected into the mold cavity, taking on the shape of the mold cavity. The cooling time varies according to the size and complexity of the part being manufactured.

  • 4
    Mold Opening and Part Ejection

    The mold is opened and the part is ejected from the cavity when it has cooled and solidified. Ejector pins are often used to force the item out of the mold.

  • 5
    Trimming and Finishing

    Following the ejection of the part from the mold, any surplus material or rough edges are removed with various instruments such as saws or grinders. To attain the proper surface finish, the part may also go through further finishing operations such as polishing or coating.

  • 6
    Quality Control

    The final step is to inspect the part to confirm that it fulfils the necessary requirements. This may entail checking the dimensions and tolerances of the part with various measurement equipment such as calipers or micrometers.

Zinc Die Casting FAQs

  • Q

    Why is zinc used for die casting?


    Zinc strength, ductility, and stability enable specialists to create a more durable product. This high ductility makes zinc perfect for die casting processes that require pressure and expansion to be maintained without fracturing.

  • Q

    Why is zinc used for die casting rather than steel?


    Die-cast zinc is cheaper to produce than stainless steel. Stainless steel is more expensive to produce than zinc. Zinc alloys are more resistant than stainless steel and are used for thin-walled profiles. Stainless steel is far inferior to zinc alloy in terms of thin-walled sections.

  • Q

    Is zinc die cast strong?


    Zinc casting alloys are strong, long-lasting, and low-cost engineering materials. No other alloy system combines strength, toughness, rigidity, bearing performance, and cost-effective castability.

  • Q

    Why is zinc used for die casting?


    The combination of low melting point, excellent fluidity, dimensional accuracy, surface finish, strength, corrosion resistance, and recyclability makes zinc a favorable material for die casting. These properties contribute to the production of high-quality, precise, and cost-effective parts in various industries.

  • Q

    Why is zinc the easiest metal to cast?


    The melting temperature is one of the most visible variances. Zinc melts at a lower temperature than aluminum, magnesium, and brass, at 723°F. As a result, zinc requires less energy to reach a molten state than other die cast metals.

  • Q

    Does diecast zinc rust?


    When exposed to moisture and other environmental conditions, zinc corrodes. However, the corrosion that occurs does not cause the part to rust in a brown and orange color or considerably weaken it. As a result, zinc die casting is both economical and robust, and it may be employed in a range of industries.

  • Q

    How thick is a zinc die cast?


    The required usual minimum wall thickness in zinc die castings is 0.040" (compared to 0.060" in aluminium die casting). However, thanks to today's better die casting and alloy technology, die casting components with wall thicknesses as low as 0.008" have been produced.

  • Q

    What is the hardness of die cast zinc?


    According to research, EZACTM is the most creep resistant zinc die casting alloy, outperforming ZAMAK 5 and ZA-8 by an order of magnitude. This alloy is likewise highly strong, with yield strength (57 ksi) and hardness (102-134 brinell) similar to ZA-27.
