Injection blow molding is a manufacturing process used to create hollow plastic parts. It combines two techniques: injection molding and blow molding. First, molten plastic is injected into a mold to form a preform, which is a small, solid piece. Then, air is blown into the preform, expanding it to fit the shape of a larger mold. This method is commonly used for producing items like bottles and containers. Injection blow molding offers advantages such as precise control over wall thickness and the ability to create complex shapes. It is efficient and suitable for high-volume production, making it popular in the packaging industry.
