China's High Quality Die Casting Company

Yontone is a leading provider of customized aluminum and zinc die casting solutions for a wide range of industries.


What is die casting?

Die casting is a process to form material ingot into the shape you designed.

  1. Using an electric furnace or centralized melting furnace, turn metal ingot into metal liquid
  2. Using a die casting machine, with high speed and high pressure, to feed the metal liquid into a steel permanent mold
  3. After a period (calculated by the engineer), the product is cooled and formed. Eject the parts from the machine.

Die Casting Parts with Different Materials

Die casting is a complex process that requires both good die design and good die casting process design. Yontone can do both.

Here is a simplified overview of the die casting process:

  1. The molten metal is injected into the die cavity through a runner and gate system.
  2. The metal solidifies and the casting is formed.
  3. The casting is ejected from the die and the process repeats.

The gate is a critical component of the die casting process. It accelerates the flow of metal into the cavity and makes it easy to separate the runner from the casting.

Yontone has extensive experience in designing and manufacturing die casting dies and processes for a variety of materials, including aluminum alloy, zinc alloy, copper alloy, and magnesium alloy.

Below are some die casting parts that Yontone has made for reference:

aluminum die casting Mower housing power tool parts Transmission box, water pump, Bevel Slide Miter Saw upper guard housing,safety cover,

Aluminum alloy and magnesium alloy are two common materials of cold chamber die casting.

The picture shows some aluminum alloy die casting products, including mower housing, power tool parts, transmission box, water pump, bevel slide miter saw upper guard housing and safety cover.

These products are eventually assembled, so they all need to be machined after the aluminum die casting process. Surface treatment is also required, but it must be done before machining. Therefore, it is important to protect the surface during CNC machining. These products are all appearance parts, so they must be free of scratches.

Magnesium alloy is lighter than aluminum alloy, its tensile strength and fatigue strength are not as good as aluminum alloy. It is also easy to oxidize, and magnesium alloy powder is flammable, the production process is dangerous. Therefore, most products are now produced by aluminum die casting. The cost and performance are optimal.

zinc die casting door hinge, radiator trim penal, parking meter housing, integrated power module, marin hardware, Evaporator Line Base Plate

Zinc alloy die casting is typically produced using a hot chamber die casting machine. This is because hot chamber die casting machines are more efficient and cost-effective than cold chamber die casting machines.

The picture shows zinc alloy die casting products, including door hinges, radiator trim panels, parking meter housings, integrated power modules, marine hardware, and evaporator line base plates.

Zinc alloy has a density that is nearly 2.5 times that of aluminum. It has good casting properties and can be used to produce complex, thin-walled precision parts with smooth surfaces. It has a low melting point of 385℃ and is easy to die cast. Zinc alloy die casting products can be subjected to a variety of surface treatments, such as chrome plating, electroplating, electroless nickel plating, painting, and spraying. Zinc alloy is corrosion-resistant, so it is a popular choice for marine parts, door handles, and bathroom faucets and handles.

brass die casting swimming pool light housing, handle, knob

Commonly used 59 brass has a die casting temperature of 900-1020°C. Brass has good electrical conductivity, corrosion resistance, strength, and hardness. Die casting can produce brass products with higher precision than sand casting. The pictures show a pool bottom lamp shell, a juicer knob, and a handle. Brass has good mechanical properties and wear resistance, and can also be used to manufacture precision instruments, ship parts, gun and shell casings, and coins.

Brass alloy die casting has a high die casting temperature, and the service life of the mold is far less than that of aluminum alloy die casting. High die casting temperatures can cause brass die casting molds to crack, making it difficult to demold and affecting product appearance. Therefore, regular maintenance is essential.

The price and density of copper materials are also high. Therefore, copper die casting is relatively expensive overall and is suitable for high-end products.

Die casting parts can be used in different industries: automotive, medical, aerospace, electronics, telecommunications, energy, new energy, marine, power tools, power systems, etc.

Yontone is an OEM die casting manufacturing company, every part can be customized, we accept drawings for production, and also samples for reverse designing.

Die Casting Machine and It's Accessories

Die casting machines are divided into hot chamber and cold chamber types. The key difference is whether the injection system is immersed in the molten metal.

Hot chamber die casting machines are typically used to cast zinc alloys, while cold chamber die casting machines can be used to cast a wider range of alloys, including aluminum, copper, magnesium, and zinc.

Die casting machines are the main equipment in a die casting unit. Other equipment includes auxiliary machines, furnaces, mold temperature controllers, pick-up robots, spray robots, die-spray packages, multi-link automatic ladles, foundry plus robots for extracting, trim presses, molten material handlers, etc.

Yontone’s die-casting workshop is equipped with the most advanced robotic automation equipment, including mechanical robotic arms and automatic transmit systems. This helps to reduce labor costs and improve production efficiency.

Trimming Machine

A trimming machine for die casting parts is a machine that is used to remove excess material from die casting parts. This process is necessary to ensure that the parts meet the required specifications and to improve their appearance.

sand blasting
Sand Blasting Machine

Shot blasting machines use high-speed rotating nozzles to propel steel or iron shot against the surface of die casting part, cleaning and strengthening it. Shot-blasted parts have a uniform metallic sheen, which can improve product appearance. They also deburr the surface and increase surface adhesion, which is often necessary before surface treatment.
