Materials for Die-Casting
Die-casting is a manufacturing process that involves injecting molten metal under high pressure into a mold cavity. The selection of materials for die-casting is crucial to achieving the desired quality and precision of the finished products. The most common materials used in die-casting are metals that possess good fluidity, strength, and the ability to withstand high temperatures.
