Vacuum Zinc Die Casting

Gc Precision Mold Co.ltd  is an experienced vacuum zinc die casting manufacturer.

What is Zinc die casting

Zinc die casting is a process in which molten zinc is injected under high pressure into a die (a tool with a specific shape) to produce parts. The process is known for producing parts with good dimensional accuracy and surface finish. It is commonly used to produce small, complex-shaped zinc alloy parts, such as those found in the electronics, automotive, funiture, and hardware industries. The die casting process is fast and efficient, and it allows for the production of a large volume of parts in a short period of time. The main advantage of zinc die casting is that it allows for the production of parts with a high level of detail and accuracy.

Zinc Die Casting

There two kinds of die casting processes available for zinc high pressure die casting. Commonly we cast small zinc die cast products by hot chamber die casting machine, and larger parts by cold chamber die casting machines. Thus before we start zinc die casting design, we will confirmed with customers which kinds of machine he prefers. Except of this issue, the design of zinc die casting is quite the same as that of aluminum die casting.

Zinc alloy die casting mold

A zinc alloy die casting mold is a tool that is used in the zinc die casting process to shape molten zinc into a specific shape. The mold consists of two halves that are made from hardened steel or another strong and durable material. One half of the mold is stationary which we called cavity side, while the other half is movable which we called core side. The two halves of the mold fit together precisely and are held together with a clamping force during the casting process.

Zinc alloy die casting molds can be designed and manufactured to produce a wide range of parts with different shapes and sizes. They can be used to produce small, intricate parts as well as larger, more complex parts. The design of the mold is an important factor in the quality and accuracy of the finished parts.

Die cast zinc material properties

Our Zinc Metals is very beneficial for polished die castings, particularly those which are gold plated, or coated with zirconium nitride (ZrN), titanium nitride (TiN) or chromium nitride (CrN), by physical vapour phase deposition (PVD) processes. Zinc alloys used in die casting have a number of unique material properties:

1.  High strength and hardness: Zinc alloys have a high strength-to-weight ratio and are able to withstand high levels of stress and wear.
2. Good corrosion resistance: Zinc alloys have good corrosion resistance, although they are not as corrosion-resistant as some other metals.
3. Good castability: Zinc alloys have good castability, meaning that they are able to be easily shaped using the die casting process.
4. Low melting point: Zinc has a relatively low melting point, which makes it well-suited for use in the die casting process.
5. Good electrical conductivity: Zinc alloys have good electrical conductivity, making them suitable for use in electrical components and other applications where electrical conductivity is important.
6. Good finishing characteristics: Zinc alloys have good finishing characteristics, which means that they can be easily painted, plated, or otherwise finished to improve their appearance or protect them from corrosion.

Advantages of zinc die casting

There are several advantages to using zinc die casting:

1. High production rates: Zinc die casting allows for the production of a large volume of parts in a short period of time. This makes it a cost-effective choice for high-volume production runs.
2. Good dimensional accuracy: Zinc die casting produces parts with good dimensional accuracy, which means that they have precise and consistent dimensions.
3. Good surface finish: Zinc die casting produces parts with a smooth, attractive surface finish.
4. Strong and durable: Zinc is a strong and durable material, and parts made from zinc die casting are able to withstand high levels of stress and wear.
5. Versatility: Zinc die casting can be used to produce a wide range of parts with different shapes and sizes, making it a versatile option for manufacturers.
6. Cost-effective: Zinc is a relatively inexpensive material, which makes zinc die casting a cost-effective option for many manufacturers.

Disadvantages of zinc die casting

Zinc die casting parts have many advantages, but there some of disadvantages as well:

1. Limited design options: The design of the part is limited by the capabilities of the die casting process. It may not be possible to produce certain shapes or features using zinc die casting.
2. Porosity: Zinc alloys have a tendency to contain small pores or voids, which can affect the strength and durability of the finished part.
3. Limited material options: Zinc die casting is limited to zinc alloys, which may not be suitable for all applications.
4. Size limitations: Compare to aluminum die casting and plastic injection molding process. The size of the parts that can be produced using zinc die casting is limited by the size of the die casting machine and the capacity of the mold.
5. Finishing requirements: Zinc die cast parts often require additional finishing processes, such as painting or plating, to improve their appearance or protect them from corrosion.
6. Risk of defects: The die casting process is subject to a number of potential defects, such as porosity, warping, and surface blemishes, which can affect the quality of the finished parts.

Applications of zinc die casting parts

Zinc die casting parts are used to produce a wide range of parts for a variety of applications, including:

1. Automotive: Zinc die casting is used to produce a variety of parts for the automotive industry, including engine parts, transmission parts, and suspension components.
2. Electronics: Zinc die casting is used to produce small, complex-shaped parts for the electronics industry, such as connectors, switches, and housings.
3. Hardware: Zinc die casting is used to produce a wide range of hardware components, such as locks, handles, and hinges.
4. Military: Zinc die casting is used to produce parts for military applications, such as weapon components and defense equipment.
5. Consumer goods: Zinc die casting is used to produce parts for a wide range of consumer goods, including toys, appliances, and sporting goods.
6. Medical: Zinc die casting is used to produce parts for the medical industry, such as surgical instruments and medical devices.
7. Computer components: Zinc die casting parts are often used to produce parts for computer components, such as connectors, switches, and housings.
8. Bathroom fittings: Zinc die casting parts are often used to produce parts for bathroom fittings, such as faucets, showerheads, and handles.
9. lighting enclosures: Zinc die casting is often used to produce parts for lighting enclosures, such as lamp bases and housing for light fixtures.
