Die casting is a manufacturing process that involves forcing molten metal into a mold cavity under high pressure. This method is commonly used to create complex shapes with high precision and smooth surfaces. The molds, often made from steel, can be reused multiple times, making die casting an efficient option for mass production. The process is widely used for producing parts in various industries, including automotive, electronics, and aerospace. Common materials used in die casting include aluminum, zinc, and magnesium, which offer excellent strength-to-weight ratios. This technique allows for the creation of lightweight yet durable components.
