If you're looking to manufacture die-cast components, then you need to choose the right casting process. This is an important step. If you choose the right casting method, you produce better-quality components.
In some cases, squeeze casting is the best option. How does this kind of die casting work and what are its advantages?
What Is Squeeze Casting?
Like any kind of die casting, squeeze casting involves injecting a molten metal into a mould. The difference here is the way you treat the metal in the mould and the time the process takes.
In this process, the metal is poured into the holding part of the mould. Rather than being left to set, the die is then pushed down hard but slowly. This pressure forces the metal right down into the mould. Once the pressure releases, the metal can set and harden into its shape.
What Are the Advantages of Squeeze Casting?
Choosing a squeeze-casting process has some benefits. Depending on the components you want to cast and their purpose, this can provide a suitable solution. For example, this method works well for components that need to pass stringent safety measures because they'll operate in stressful environments.
Some die-casting techniques don't give you a completely even fill. Components might not be 100% complete; they may have weak spots where the metal didn't get a full spread.
The pressurisation you get in squeeze casting prevents these problems. The squeeze forces the molten metal into its cast slowly and forcefully. The metal then spreads right through the cast. It fills the space evenly and fully, leading to better-quality components. The hardened metal is dense and strong. You'll get fewer imperfections, and your components will be better able to do their job.
If the metal is spread evenly and fully, it also wears better. There aren't any weak areas that might fail or break when the component is used.
Squeeze casting also removes porosity problems. Your components won't be as likely to have problems with air or gas bubbles settling inside the metal after it hardens. You can also safely heat treat squeeze-cast products after they are manufactured.
If you think that squeeze casting is the way forward for you, contact die casting companies. They can take a look at what you need and help you find the most effective methodology.
