Ordering your Die Casting

Your part drawings will be reviewed in house by PA International engineers. The best suited type of casting will be chosen for your part according to the intended use and complexity of the design. Off-tool samples will be provided to you after drawings are approved. We tailor for small production runs as well, been a China based Casting Manufacturer an important part of our business is short runs and small quantities of customized shapes which include but is not limited to building & construction, transportation, consumer goods, packaging and engineering products. Casting Options:

  • The investment casting is also called lost wax casting. It’s generally used for complicated shapes. The unit cost by investment casting is higher, but it has a lower tooling cost.
  • The gravity casting is permanent mold casting. The gravity casting main advantages are the reusable mold, good surface finish, good dimensional accuracy and high production rates.
  • The die casting is suitable for applications that require good surface finish and dimensional consistency. Manufacturing of parts is relatively simple, which keeps the incremental cost per item low.
  • Sand casting or sand mold casting used for metal parts that are ranging from a couple ounces to several tons. The small parts include gears, pulleys, crankshafts, connecting rods, and the larger parts include large equipment housings, engine blocks, cylinder heads and transmission cases.



    Die casting is a manufacturing process in which molten metal is poured or forced into steel molds. The molds—also known as tools or dies—are created using steel and are specially designed for each project. This allows each component to be created with accuracy and repeatability. Aluminum, zinc, and magnesium are the most commonly used die casting alloys.

    Die Casting Advantages

    Die casting can have significant advantages over other manufacturing processes, which often lead to major cost savings, not only in the part price itself but also in the overall cost of production. When you cast a part, you can create complex net shapes, including external threads and complex internal features with minimal draft angles—minimizing secondary operations. You can also combine multiple parts into a single part, eliminating assembly operations and lowering labor costs, with the added benefits of simplified stock control and greater component consistency.

    Other benefits include:

    • Variable wall thicknesses
    • Tighter tolerances
    • Fewer steps from raw material to finished part
    • Fast production cycle times
    • Reduction in material scrap
    • Long tool life, especially for zinc and magnesium

    Die Casting Alloys

    Zinc, aluminum, and magnesium are the three main die casting alloys. They are normally non-ferrous and their mechanical properties vary greatly to fit almost every type of application a manufacturer may need. Not only can die cast alloys withstand high operating temperatures, but they are also fully recyclable. Die cast alloys also have:

    Die casting zinc, die casting aluminum, die casting magnesium


    • Good corrosion resistance
    • High strength and hardness
    • High thermal conductivity
    • High electrical conductivity
    • Outstanding EMI/RFI shielding properties
    • Good finishing characteristics

    Separately, each die cast alloy offers a variety of benefits that the other may not offer. That is one of the great things about die casting, you do not have to be limited when it comes to choosing the right metal.

    Die Cast Process

    There isn’t one single process that can suit every project. Each project is different which is why PAI offers multiple solutions for all die casting needs. This ensures the right process is always used for the right application. At PAI, we offer three different types of die casting processes.


    Used for zinc, some magnesium alloys, and other low-melting, hot-chamber die casting is a great option for alloys that do not readily attack and erode metal pots, cylinders, and plungers.


    Better suited for metals with high melting points such as aluminum, during cold-chamber die casting, metal is liquefied and then ladled into a cold chamber where a hydraulically operated plunger pushes the metal into the die.

    Injected Metal Assembly

    Over the past 30 years, we have developed and refined our innovative; one-step manufacturing solution, Injected Metal Assembly. IMA outperforms most adhesives used for small component joining and assembly production and reduces manufacturing costs.

    Multi-Slide & Conventional Die Casting

    At PAI, we offer two different types of tooling: multi-slide and conventional. Each has their own unique benefits and our skilled engineers can help decide which tooling is best for each project.

    Benefits of Multi-Slide Tooling

    Our proprietary multi-slide tooling technology offers a number of unique advantages, including:

    • Net shape first time
    • Eliminates secondary operations like assembly and machining
    • Complex geometry and tight tolerances at higher speeds
    • Minimum part-to-part variation compared to conventional multi-cavity dies
    • Compact tooling that is less prone to parting-line variation and its negative effect on the finished part’s dimensional tolerances

    Benefits of Conventional Tooling

    Conventional die cast tooling is designed with single or multiple cavities. The tool is designed to be efficient and cut down on secondary operations which help lower costs. Other benefits of conventional die cast tooling, include:

    • Dies that are designed to efficiently manage high volume production
    • Net shape die casting, with design focused to avoid secondary operations
    • Steel braced dies to aid in the longevity of the tool
    • Efficient production with properly planned cooling and water lines
