Die casting is a manufacturing process that involves forcing molten metal into a mold cavity under high pressure. This method is widely used for producing parts with intricate shapes and close tolerances. CQS specializes in non-ferrous die casting, primarily focusing on aluminum and zinc alloys. The company’s expertise in these materials allows for the production of lightweight yet durable components that are essential in various applications, from automotive to electronics.

Investment casting, on the other hand, uses a similar approach but typically involves creating a mold from a solid model, which can be made from various materials. High precision in casting is achieved through the meticulous control of factors such as temperature, pressure, and pouring speed, which are crucial for ensuring that the molten metal fills the mold evenly and accurately.

Investment casting, also known as lost-wax casting, is one of the oldest techniques and is widely favored for its ability to create complex shapes with smooth surfaces. Here, a wax pattern is coated with a ceramic material. Once the ceramic is hardened, the wax is melted away, leaving a cavity that is then filled with molten aluminum. This process allows for high detail and accuracy and is often used in industries where precision is paramount, such as aerospace and medical devices.
