Advantages of pressure die casting for manufacturers and end users For one thing, it has high structural integrity-the pieces are resilient and able to withstand severe conditions.Second, the production process is highly efficient: faster rates of supply, lower costs per part-especially in mass production campaigns where die casting is a common practice.Third, cast parts have an excellent surface finish. This can reduce the need to finish them further; it saves time and expense.Finally, being able to configure complicated shapes and thin walls is helpful in creating lightweight items. It's an important need for fuel-efficient performance in the automotive and aerospace industries.
