Method of making a blow molded article from a preform including: a) providing a preform of a thermoplastic material having a plurality of effect structures each having an effect surface having a normal with an orientation, the preform having a body with one or more walls and an opening, wherein at least a portion of the one or more walls of the preform has a three-dimensional pattern of cavities and/or protrusions thereon; and b) blow molding the preform to form a blow molded article, wherein the step of blow molding the preform changes the orientation of the normal of at least some of the effect surfaces of the effect structures to create a visual effect in at least one wall of the blow molded article.

A composite preform including a preform and a plastic member in close contact with the outer surface of the preform is made by preparing the preform made of plastic material and arranging the plastic member to surround the outer surface of the preform. Subsequently, the composite preform is heated and inserted in a blow molding die and undergoes blow molding in the blow molding die, by which the preform and the plastic member of the composite preform are inflated integrally and a composite container is obtained.

The invention relates to a tank of plastics material produced by blow-molding of a parison, incorporating a welding spout, of a shape projecting from its outer surface which has an edge configured to be welded to a corresponding edge of an attached part, the welding spout ending axially, on an inside of the tank, in a shape resulting from contact molding between the parison and a molding component, in which the welding spout ends axially on an outside of the tank in a shape resulting from contact molding between the parison and a molding component.

The present invention provides a manufacturing device of a battery case including a first mold including a first space part having a shape corresponding to a storage part formed therein; a second mold including a second space part having a shape corresponding to the storage part and a through-hole communicating with the second space part formed therein, and coupled to the first mold with a laminate sheet interposed therebetween; and an air pressure regulator mounted in the through-hole in a state in which the first space part and the second space part are isolated from the outside, and increasing or decreasing an air pressure of the second space part through the through-hole to stretch and modify the laminate sheet into a shape corresponding to the first space part or the second space part.

Introduced here are carrier tape assemblies that can improve efficiency and reduce costs when utilized in the handling, transport, or storage of semiconductor components. A carrier tape assembly can include an adhesive film affixed to an elongated and/or extruded carrier tape. For example, the adhesive film may be integrally laminated onto the top surface of the elongate carrier tape as a single continuous (i.e., unbroken) sheet. The adhesive film may substantially conform to the top surface of the elongate carrier tape, including any punched cavities for holding semiconductor components. Proper securement of the semiconductor components to the carrier tape assembly depends on the adhesive property of the constituent material(s) of the adhesive film.
