What is the difference between die casting and casting?

What is Casting?

Before we dive into our Yaopeng topic on casting, let's check how you can define it. Silversmiths cast things — they use metal and then make stuff. It begins with pouring the molten hot metal into a mold. Think of something that resembles a mold to hold the metal until it cools. The metal then needs a little bit of time to set after being poured in. 

Casting is one of the oldest methods of mixing different mediums, utilized for thousands of years to create a variety of items ranging from basic implements to ornamental statues. One of the Casting And Forging great things about casting is it has the ability to form different shapes and sizes, which can be very advantageous for many projects.

What is Die Casting?

Next up, die casting. Die casting differs from normal casting to an extent. While die casting also pours the metal into the mold, it uses a machine that pushes the metal into a mold. It is a heavy-duty machine called pressure die casting that exerts tremendous forces to make sure molten metal fills all crevices of the dye.

Due to this pressure, the surface finish for die casted parts seem super fine and clean like it was done with precision. So this technique is useful for manufacturing a number of smaller components that need to be fitted precisely, such as those found in car engines.

Difference Between Die Casting and Casting

Having understood casting and die casting, let us try to differentiate these two a bit more. In most cases, die casting is faster than casting. In other words, it has the ability to produce components quickly, making a rapid prototyping technique ideal when larger quantity production is required. Die casting can use a machine to hold the metal really tightly, which helps create really precise parts.

Casting, however, requires a longer time since you need to give the metal some time to cool down and solidify. Casting can also make it more difficult to create precise parts. That said, casting works well for larger tools or complex shapes that might be too difficult to tackle with 90 Degre die casting.

Which One Should You Choose?

Which one should you choose then: die casting or casting? you may ask. You can do both, but what are you trying to create? If you have hundreds of small but incredibly precise parts (like the engine pieces in a car) that need to be made, then die casting is likely your best option.

However, if you are producing something large (for example a statue or a machine part that does not need to be very accurate), then maybe casting will be better. Ultimately it depends on what you are creating and how you want it to look.

Advantages and Disadvantages of Each Approach

The die casting and easy stuff have their cnc machining benefits and inconveniences. Here are some of them:

Advantages of Die Casting:

It is quicker than traditional casting and creates parts with a very high degree of precision.

Die cast parts usually have a very smooth surface and require little further work to finish.

Die Casting vs Casting Summary Analysis

To sum it up, die casting and casting compliment each other just like the yin and yang. Which of these is the right one for you really depends on what you want to produce and how accurate the parts need to be. Die casting cnc metal is one area of expertise for us at Yaopeng, this means we can produce the quality parts our customers need. We hope at least you have may learned something new and exciting, as always Thank You for reading.
