Blow molding machines are specialized equipment used to create hollow plastic products. They work by heating plastic until it becomes pliable, then forming it into a mold using air pressure. This process is commonly used to produce items like bottles, containers, and tanks. There are different types of blow molding processes, including extrusion blow molding and injection blow molding. Each method has its own advantages and is chosen based on the specific requirements of the product being made. These machines are essential in the packaging industry and other sectors that require durable plastic items.
