PET bottle mold making involves designing and manufacturing molds, typically from metal (steel or aluminum), to create hollow bottles using the blow molding process. The process begins with creating bottle designs using Computer-Aided Design (CAD) software, followed by 3D printing for prototypes, and finally using advanced CNC machinery to produce the high-precision metal molds. The molds are then used in a blow molding machine, where a molten PET preform is heated and inflated with air to take the mold's shape, resulting in a finished bottle after cooling.
