A production device for a fuel tank, having two or more built-in components attached to an inside of a fuel tank body when the fuel tank body is formed, includes: jigs configured to have the built-in components placed thereon; and a feed robot, as a feed device, configured to feed the built-in components, along with the jigs having the built-in components placed thereon, to a position below molding dies. The feed device may feed the jig, having the built-in components placed thereon, to the position via a subsurface feed path leading to the position.

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 dual or multi-prong blow pin having air channels and a water cooling manifold integrally formed in the blow mold pin. The pin is formed by 3D depositing a metal such as stainless steel, which permits the formation of a blow mold pin having an intricate shape with internal air and water channels. The use of 3D deposition allows the manufacture such a blow mold pin, which may be difficult or impossible to form using conventional casting and machining methods.
