  1. The Advantages of Die Casting

    Leave a Comment

    Die casting is one of the most versatile and prolific metalworking processes, creating countless varieties of parts used in almost every industry imaginable.  Interestingly enough, it dates back to the mid 1800’s, and today, innovations keep it moving forward.

    There are many distinct advantages to die casting over other processes, but many people wonder what they are, and how die casting differs.

    For instance, what is the difference between die casting and plastic molding, and is one better than the other? In general, die casting produces stronger parts with closer tolerances that have greater stability and durability. Die cast parts also have greater resistance to temperature extremes and superior electrical properties.

    When compared to plastic injection moldings with the same dimensions, die cast parts are stronger. Because they are not joined or welded together, they are as strong as the alloy that makes them, rather than the actual joining process. Another benefit is that parts that have been die cast can have many finishing techniques and surfaces, and can easily be designed to have a certain desired appearance.

    Sand casting is another technique that is compared to die casting. Sand cast parts typically have a rough surface appearance as well as surface variations and, occasionally, impurities. Compared to sand casting, die casting produces parts that have thinner walls and smoother surfaces. They also have closer dimensional limits.

    Overall, the die casting process is much more economical than sand casting. The production is faster, finishing costs are lower, and significant overall savings are seen.

    While there are always certain exceptions for specific applications, the advantages of die casting over these two processes, and others, are many.
