A method and apparatus for blow molding a case for housing an object, such as a tool, is disclosed generally comprising first and second mold portions located adjacent each other to create separate cavities for forming base and lid portions of a case and a punch for each portion corresponding to the outline of an object. In certain embodiments, the punch protrudes into the cavity during blow molding to create a sidewall to facilitate a press fit. In some embodiments, additional punches and/or re...

A dual-filled gum piece is provided having a first cavity filled with a liquid filling and a second cavity filled with a powder filling. The gum pieces are produced by extruding a gum rope having two separate channels respectively filled with liquid and powder, sizing and shaping the gum rope, cooling the gum rope, cutting the rope into discrete gum pieces, and finally cooling the gum pieces. The gum pieces optionally can be coated with a hard coating. In other aspects for single- and dual-fille...

The invention provides a method of inflation extrusion molding, comprising: introducing one or more resin materials extruded from one or more extruders into a die; subsequently extruding the resin material(s) from the die and inflating the extrudate into a cylindrical shape having a predetermined diameter by blown-film extrusion; and then passing the cylindrical inflated resin material through a space between stabilizers which face each other at a predetermined angle, to deform the cylindrical r...

Apparatus and method for making a molded plastic article having a stretched and crystallized neck finish. In one embodiment, a series of platforms are carried by a conveying apparatus for transporting a series of molded plastic articles along a predetermined path of travel through one or more treatment stations. At a finish widening station, the molded article, having a relatively wide and thin-walled blow-molded body portion, and a relatively narrow and thick-walled unexpanded neck finish porti...

The invention relates to a molding device for blowing thermoplastic recipients of various heights, said device comprising a mould provided with two mould halves and a mould bottom which are mutually mobile. Each mould half comprises a mould carrier, a chill carrier and a chill, said two chills and the mould bottom comprising mould impressions, which together define a molding cavity. The inventive device also comprises means for compensating the blowing pressure, said means being provided between...

Apparatus for making a reinforced absorbent member includes a forming chamber adapted to contain a fluent fibrous material. A forming surface is moveable within the forming chamber along an arcuate path generally from an entrance of the forming chamber to an exit thereof. The forming surface is adapted to collect fibrous material thereon to form the absorbent member. A source of reinforcing web is disposed generally exterior of the forming chamber. The forming chamber has an opening through whic...

A frame, kit and method for forming a positive impression of an object. The kit includes a supply of impression medium, the frame with a backboard, and a solidifying casting compound. A negative impression is temporarily made in the impression medium, then a casting compound can be poured into the resulting impression so as to form a positive impression which acts as a representative of the body portion being produced.

A machine for processing individual food items comprises a mold plate having multiple longitudinally spaced transverse rows of cavities. The mold plate slides such that the rows of cavities sequentially communicate with a fill slot in a fill plate. Bulk food material fills the cavities and displaces air from them into a breather plate. The breather plate has one or more longitudinal grooves in a working surface. The fill plate has one or more longitudinal grooves in a working surface that commun...

A blow molding system for a thermoplastic blank which is supported in a mold. The system includes a fixed tubular body connected to a high-pressure fluid source and, at the lower end thereof, supporting moveable equipment consisting of a tuyere, the tuyere being defined laterally by a terminal sleeve of the moveable equipment and the bottom thereof being the front wall of the body, wherein the lateral inner wall of the sleeve is configured in such a way that the pressure of a fluid inside the tu...
