A method of forming a blow molded plastic article wherein the article comprises an airflow conduit, comprising: providing a first sheet of insulation material located on a insulation carrier; providing a blow molding mold including two halves and having a molding surface defining a molding cavity to form the article; locating the insulation carrier between the two halves of the blow molding mold; transferring the first sheet of insulation material from the insulation carrier to the blow molding mold; introducing an extrudate of thermoplastic composition between the two halves of the blow molding mold; closing the blow molding mold; forming the extrudate to a shape of the mold cavity of the blow molding mold to form the article; and bonding the extrudate to the first sheet of insulation material as the extrudate is being formed to the shape of the mold cavity.

Methods and apparatus for molding a vessel, such as a bottle, with a high quality sealing surface are described herein. In one embodiment, a stepped blow pin can be used to form the sealing surface of a bottle. A stepped blow pin can include a body with a distal end and a proximal end. The blow pin can include a first region that includes a first diameter and a first engagement surface. The blow pin can further include a second region that includes a second diameter. The second region can be positioned between the first region and the distal end. A transition section can be positioned between the first region and second region. The blow pin can also include a top surface position at the proximal end, and a bottom surface positioned at the distal end.

The present invention relates to molded foam having no hollow space caused in a plate-shaped portion. The molded foam comprises a tube body and a plate-shaped portion joined to the outer side of the tube body. The expansion ratio of the molded foam is lower than two, and a value of a thickness B/a thickness A as a relationship between the thickness A of the tube body at the periphery of a point joined to the plate-shaped portion and the thickness B of the plate-shaped portion is less than 2.82.

A blow molding system comprising an extrusion system including at least one extruder configured to extrude a parison having an interior cavity, a blow pin configured to extend into the interior cavity of the parison extruded from the extrusion system, and a mold assembly defining a mold chamber configured to receive the parison, the mold assembly including a plurality of mold cavities each facing the mold chamber and defining a profile of a sole component of an article of footwear. A method comprising the blow molding system forms a plurality of sole plates for an article of footwear.
