Extrusion blow molding (EBM)
Extrusion blow molding is a method of manufacturing hollow thermoplastic parts. Well-known blow molding objects include bottles, barrels, cans, boxes and all containers for packaging food, beverages, cosmetics, medicines and daily necessities. Large blow-molded containers are usually used for packaging chemical products, lubricants and bulk materials.

Injection blow molding (IBM)
In the injection blow molding process, the injection machine first injects molten plastic into the injection mold to form a tube blank, which is formed on a hollow punch with micropores on the wall; then it is moved to the blow mold while hot; then the mold is closed and compressed air is introduced from the pipe of the core rod to inflate the blank and stick it to the cavity wall of the mold; finally, after pressure maintenance and cooling, the compressed air is released and the mold is opened to remove the plastic part.

Injection Stretch Blow Molding (ISBM)
Injection Stretch Blow Molding, also known as Injection Stretch Blow, is a process that first uses an injection molding machine to mold a preform, then longitudinally stretches the hot preform, and then introduces compressed air to stretch it transversely to obtain a product with the same shape as the mold cavity. According to the product molding process, it can be divided into a one-step injection stretch blow molding process and a two-step injection stretch blow molding process.
