What is Zinc Die Casting Mold?

Zinc alloy die casting mold is suitable for the zinc alloy die casting process.

After the zinc alloy is melted, the hot chamber die-casting machine injects the high-temperature zinc alloy liquid into the steel mold at high speed through the piston, makes it cool and solidify in the mold, and finally obtains parts or components that meet the requirements in shape and size.

Because the die-casting temperature of zinc alloy is much lower than that of aluminum alloy and brass alloy. Therefore, the requirements for mold steel are not high. Usually, ordinary hot work die steel is fine. To increase the lifetime of zinc alloy die-casting molds, it is necessary to improve the wear resistance and hardness of the mold. We use H13-type hot die steel, high-temperature quenching, high-temperature tempering, and the hardness is generally around HRC50. Cost-effective, and long lifetime.
To further improve the working life of the mold, we can use high-temperature quenching and high-temperature tempering for hot work die steel with a hardness above HRC52, such as LG1.2367, YXR33, 8566X, W360, etc.
The materials above are more expensive, we can also choose good quality H13 as the base material, and improve the wear resistance through surface treatment to achieve the purpose of improving the lifetime of the mold.

Zinc Die Casting Molds Making Process

Zinc alloy has a low melting point, good fluidity, and less impact and wear on the mold. The service life of zinc alloy die-casting molds is generally above 200,000-500,000 shots mold times. A good zinc alloy die-casting mold can reach more than 100w mold times.
However, while considering the number of shots, we also need to consider the price of the mold per unit mold. How much does it cost for the same mold for 500,000 molds? Or even 1000,000 shots?
Yontone as a zinc die casting mold maker, has decades of experience in the design and production of die-casting molds, we will help customers weigh what material to use in this order is the most cost-effective, and supplying guaranteed excellent quality mould is our mission.

milling zinc die casting mould cavity

The cavity of the zinc alloy die-casting mold is a precision machining task. After processing, the cavity shape is consistent with the mold design drawings. The processed cavity needs to undergo heat treatment to meet the hardness requirements of the zinc alloy die-casting process for the mold.

EDM on zinc die casting mold cavity

Utilizing copper or graphite as electrodes, the mold is processed through Electrical Discharge Machining (EDM) on an EDM machine. This method allows for the machining of intricate shapes that are challenging to achieve through traditional mechanical machining methods. Yontone zinc die casting mold offers high precision and an excellent surface finish.

assembly the zinc alloy hot chamber die casting mould

Assemble the core, ejector pin, insert block, slider, top plate, bottom plate, mold frame, mold base, and other components together. Simultaneously, through proper fitting of the mold components, ensure good mold closure, no flash during production, and achieving excellent moldability. Once this is achieved, the zinc die casting mold is ready for production.

Advantages of Zinc Die Casting Mould

long lifetime
Long Lifetime

Because the melting point of zinc alloy is low, the service life of zinc alloy die-casting mold is longer than that of aluminum alloy and copper alloy die-casting mold. It is 200,000-500,000 shots mold times. If the maintenance is good, Yontone moulds can produce up to 1000,000 shots.
