What is Extrusion Blow Molder Machine?

Extrusion blow molding is a manufacturing process that is used to create hollow plastic products, such as bottles, containers, and tanks. An extrusion blow molder machine is the equipment used to perform this process.

The machine starts by melting plastic resin in an extruder, which is a large heated screw-type cylinder. The molten plastic is then extruded through a die that shapes it into a parison, which is a hollow tube-like shape. This parison is then clamped into a mold and inflated using compressed air, which expands it to the shape of the mold. The plastic is then cooled and solidified, and the mold is opened to release the finished product.

Extrusion blow molder machines are widely used in the plastics industry to create a variety of products in different sizes and shapes. They can be used with various types of plastic resins, including high-density polyethylene (HDPE), low-density polyethylene (LDPE), polypropylene (PP), and others. These machines can be fully automated or semi-automated, depending on the complexity of the product being manufactured.
