What are die casting molds?

Definition of Die casting molds
Die casting molds are core equipment in the die-casting process. Their core functions and characteristics can be broken down into the following three key areas:
1.Process Carrier Attributes: As the key link between the die-casting equipment and the final product, Die casting molds rapidly inject molten metal under high pressure through their cavity structure. After cooling and solidification, they form metal parts with complex shapes and high-precision dimensions. They are the core vehicle for the die-casting process to achieve "metal forming."
2.Structural Precision: The mold cavity must possess extremely high dimensional accuracy and geometric complexity to match the shape requirements of the die-cast part. Its design must balance metal flow characteristics and ease of demolding to ensure a stable die-casting process.
3.Wide Application: Die casting molds are widely used in the automotive, motor, communications equipment, new energy, lighting, and other fields. They are key equipment for efficient, mass-produced metal parts in modern manufacturing.
