What is die casting?

Die casting is a manufacturing process that involves injecting molten metal into a steel mold, or die, under high pressure. This process yields parts with exceptional accuracy, intricate detailing, and consistent quality.

This process is rapid and efficient, allowing for large-scale production with minimal waste. Die casting offers tight tolerances and precise detailing, making it suitable for various industries like automotive, electronics, and machinery. Its ability to create durable, high-quality parts with excellent surface finishes makes it a cost-effective solution for complex metal part manufacturing.

Die Casting Materials Used

Aluminum Die Casting

Aluminum is a die cast material used for producing lightweight, complicated designs. The die casting process forms precise metal parts using pressure to completely fill all cavities within a mold. Die casting works with numerous non-ferrous metals, such as aluminum and magnesium. The die itself is made from a harder metal, such as tool steel, to ensure long-term functionality with minimal production wear. This fabrication method provides an ideal solution for producing complex designs in high volumes.

Many various industries employ the use of die casting. Regardless of the specific type of aluminum selected for individual projects, aluminum in general, offers various beneficial characteristics:

  • Conductivity: Aluminum conducts electricity and thermal energy well.
  • Dimensional stability: This metal maintains good dimensional stability, even in parts with very thin walls. Aluminum’s stability also makes it an excellent choice for complex parts.
  • Mechanical properties: Aluminum offers a reasonable degree of hardness, shear strength, and tensile strength. These and other mechanical properties make aluminum a good choice for commercial and industrial parts that require reliable long-term performance.
  • Corrosion resistance: Aluminum resists corrosion and oxidation, making it useful for mitigating the risk of rust in indoor or outdoor applications.
  • Strength. Aluminum is a strong metal with an excellent strength-to-weight ratio, even maintaining its strength at high temperatures.
  • Weight: Aluminum is a lightweight metal, especially compared to steel and other popular manufacturing materials. It is essential for designing fuel-efficient vehicles, aerospace parts, handheld consumer goods, construction elements, and other products where lower component weight may improve performance.

Zinc Die Casting

Zinc die casting is used to manufacture metal parts for various applications. Die casting offers an ideal method for producing sturdy parts with a long service life within reasonably short production windows. Zinc alloys are some of the most accessible metals to die cast and offer superior strength-to-weight ratios over many other die casting metals.

Using zinc alloys as a die casting material offers numerous benefits over other die cast materials. Some benefits of zinc die casting include:

  • High Strength-to-Weight Ratio: Zinc alloys offer superior strength-to-weight ratios compared to many other die casting metals, making them suitable for producing sturdy yet lightweight parts.
  • Long Service Life: Parts manufactured through zinc die casting are known for their durability and long service life, ensuring reliability in various applications.
  • Short Production Windows: Die casting with zinc alloys enables the production of parts within reasonably short timeframes, meeting tight production schedules and deadlines.
  • Corrosion Resistance: Zinc alloys exhibit excellent corrosion resistance, making them suitable for applications exposed to harsh environmental conditions or corrosive substances.
  • Dimensional Accuracy: Zinc die casting offers high dimensional accuracy and repeatability, ensuring consistency in part dimensions and specifications.
  • Versatility: Zinc die casting can produce a wide range of complex shapes and intricate designs, providing versatility in part design and functionality.
