Tonnage in die casting refers to the amount of clamping force that is needed to hold the die closed while molten metal is injected into the cavity. This clamping force is essential to prevent the die from opening under the pressure of the injected metal, which can reach several thousand psi. The tonnage required is usually expressed in tons and is determined by various factors, including the size and shape of the part, the type of metal being cast, and the injection pressure.

Understanding Die Casting

2. Pouring Once the mold is ready, the liquid material—in most cases, molten metal—is poured into it. Precision is crucial during this stage to ensure that the material fills the mold uniformly and avoids defects.

Precision aluminum casting has emerged as a key technique in the manufacturing sector, offering unparalleled accuracy, surface finish, and mechanical properties. As industries demand components that not only meet stringent tolerances but also exhibit lightweight characteristics, aluminum casting processes have evolved to meet these challenges. This article delves into the intricacies of precision aluminum casting, its benefits, applications, and the future of this innovative manufacturing method.
