What is Die Casting

Die casting is the process of producing large quantity of Intricate and geometrically complex parts with unique designs through the use of a reusable mould created to the specific design of mass produced components. The metal for die casting, typically a non-ferrous alloy such as aluminum or zinc, is
melted in the furnace. In essence, die casting process works by pouring or injecting molten metal under high pressure into a mould cavity. The castings that are manufactured in die casting process can vary greatly in weight and size, ranging from a couple grams to hundred kilogram.
Die casting has been a specialty of Zehan Precision Casting Foundry for over 15 years. Our die casting services have been helping many mechanical engineers, product designers and architects make their designs to life with state of the art part designs and reliable quality. Provided complete system of production, quality management system and high-quality workforce, you are guaranteed quality manufacturing of your custom parts and products at highly efficient and economical method.

Advantages of Die Casting

1. High-degree customized level.
2. Higher production rate.
3. Dimensional accuracy and high stability.
4. Lightweight and superior strength.
5. Low mass production cost.
6. Multiple finishing techniques.
Application Field
Manufacturing Process
1. Design the mold.
2. Assemble the mold.
3. Injection. The molten metal is transferred from a furnace into a ladle. The ladle then pours the molten metal into shot chamber where it is ready to be injected into the clamped die. The molten metal is then forced into the die using extremely high pressure. The high pressure then holds the metal in the die until it has time to solidify.
4. Cooling. The third step in the process is cooling. After the molten metal is injected into the die, it must have time to solidify and cool. During this time the die cannot be unclamped. Once the metal has completely cooled it takes on its final shape of the casting.
5. Ejection.Once the cooling process has finished, the die halves can be unclamped and an ejection mechanism pushes the solidified casting out of the die.
6.Trimming. The final step in the die casting process is trimming. While the metal is cooling, the excess metal in the sprue and runner must be removed along with any flash that has transpired. This extra material is then trimmed away from the final casting. The trimmed sprue, runners, and flash can then be recycled and reused in the die casting process.

1. What is the typical minimum wall thickness of your zinc and Aluminum Die Castings?

The minimum or maximum cross-sectional wall thickness on any parts is very much depedent on the overall part size and design. As an example, a 0.010‘’ wall thickness may be possible if it's localized but is not possible if it is across the entire length of the 4‘’ long part. Generally, the optimum wall thickness is 0.040‘’ to 0.120‘’ and again, is related to the overall size of the part. Minimizing wall thickness also reduces the material content of a part and its cost.
2. Can you recycle gates and runners?
Yes, Zehan tries to recycle as much scrap metal as possible. Aluminum is the best and easiest metal to recycle.
3. When casting rapid prototypes via investment castings, spin or chemically bonded Sand Casting does one use the exact same metal alloy that will be utilized with mass production die casting?
No, you cannot weld a Die Cast part. It destroys the casting and due to the nature of the
alloy content no weld would occur. You can, however, solder a zinc die cast part that has ben tin-plated. This is typically done on electronic components.

4. Can you weld die Cast Parts ?
No, you cannot weld a die cast part. It destroys the casting and due to the nature of the alloy content no weld would occur. You can, however, solder a zinc die cast part that has ben tin-plated. This is typically done on electronic components.

5. Can you anodize die Cast Aluminum?
Yes, we can anodize die cast aluminum. For larger parts, it’s a functional coating that acts as a base coat for painting or provides additional corrosion resistance. For smaller parts that ‘fit in the palm of your hand’, it can be cosmetic with proper tool design and production processes.

6. Can I expect to receive die cat parts are 100% free of porosity defects?
No, porosity is inherent to the die casting process. However, with proper tool design, porosity can be minimized and localized in noncritical areas.
