How Are Preform Bottles Made? The Complete Manufacturing Process

Preform bottles are created through a two-step manufacturing process that begins with injection molding and ends with blow molding. This article walks readers through each stage of production, from melting PET granules to forming the preform through high-pressure injection. Once the preforms are created, they are reheated and placed into molds that shape them into their final bottle form. The process is efficient and allows for high-volume production, making preform bottles a versatile and widely used solution in packaging for everything from beverages to cleaning products.
