IBM or injection blow molding is one of three options for blow molding applications. Injection blow molding is used for producing more complex products. It only allows for the production of one product per injection. The melted plastic material is injected to both halves of a heated mold around a core rod. This allows for more complex products with angles and edges to be formed in the blow mold. Then the parison, along with the core, is taken out of the injection mold and placed into the blow mold. Pressurized air is then blown into the final product creating the hollow cavity of the final product.
