There are several types of blow molding processes available for producing plastic bottles, and the best one for your specific application will depend on various factors such as the bottle's size, shape, material, and quantity needed. Here are some of the most common blow molding processes used for plastic bottle production:
Extrusion Blow Molding
(EBM): EBM is the most common type of blow molding process used for producing bottles. In this process, a molten tube of plastic called a parison is extruded and then inflated using compressed air to create the desired shape. EBM is ideal for producing large quantities of bottles quickly and cost-effectively.
Injection Blow Molding (IBM): IBM is a process in which a preform is injection molded and then transferred to a blow molding station where it is inflated and cooled to create the final bottle shape. This process is often used for producing smaller bottles or those with more complex shapes.
Stretch Blow Molding (SBM): SBM is a two-stage process where a preform is first injection molded into a preform, and then the preform is reheated and stretched to its final shape using a blow molding machine. This process is often used for producing PET bottles, which are commonly used for packaging beverages.
Reheat and Blow Molding (RHB): RHB is a process in which a preform is first created using the injection molding process and then reheated and blown into its final shape using a blow molding machine. This process is often used for producing small bottles or containers with complex shapes.
Choosing the right blow molding process for your bottle will depend on various factors such as your budget, production volume, required bottle quality, and material used. A reputable blow molding manufacturer can help you choose the best process for your specific application and provide you with high-quality, cost-effective bottles.
