SYSTEM AND PROCESS FOR VACUUM MOLDING
20190134880 · 2019-05-09 · ·

A system is for making a molded article made of foamed material, including a die (1) composed of an upper section (11) and a lower section (12), separable and coupled to define a recess. A first suction (20) creates a vacuum to allow shaping a plastic film on the wall of a portion of the recess of the sections (11) and (12). A tensioner and lock (30) of the plastic film allow positioning and fastening the plastic film outside the recess.

METHOD AND FORMING TOOL FOR HOT-FORMING A FLAT THERMOPLASTIC LAMINATE
20190084214 · 2019-03-21 ·

A flat laminate element made of thermoplastic is hot-formed in a two-stage method. In a first stage, the flat laminate which includes film(s) and/or panels(n) is placed on a flat frame-shaped pallet and is heated to a forming temperature in a heating zone between two flat heat screens in a contactless manner. The edge zone of the hot flat laminate element lies on the pallet such that the laminate piece cannot be clamped in a first laminate direction but rather can be slide on the pallet in this direction. Two non-flat rigid contours which are identical or largely identical act on two opposing parallel laminate edge sections uniaxially and perpendicularly to the laminate plane and only in the first laminate direction, i.e. monodirectionally, and shape the entire heated laminate element into a monodirectionally molded blank.

20190016489 · 2019-01-17 ·

The invention relates to an upper sealing tool comprising an edge area (21) and a recess with which the upper film web is formed and the recess comprises a transitional area (22) and an inner area (23). The transitional area is located between the edge area and the inner area. The invention also relates to a packaging machine and to a method for producing a skin packaging.

Method of making a resin panel

A resin panel includes a first structure and a second structure stacked on each other. The structures includes reference surfaces that serve as the front surface and the back surface of the resin panel respectively. Each of the structures includes a plurality of protrusions protruding inwardly from the reference surface. The protrusions of the structure face the protrusions of the other structure each other. Jutting portions of linear shape are formed between adjacent protrusions of each of the structures. The structures are joined such that apical portions of the protrusions of each structure abut one another.

PARTIAL DECORATION FORMING METHOD AND PARTIAL DECORATION FORMING APPARATUS
20180178443 · 2018-06-28 · ·

To reliably perform partial decoration forming by avoiding crush deformation of a hollow structure due to a change into a pressure-reduced state even in a case where part of the hollow structure is included in a partial decoration forming range of a formed plate material. A surrounding frame body (33) is brought into contact with an upper portion of a body to be coated to surround the decoration forming range, and the body to be coated is accommodated, and an upper space (A) in a sealed state and a lower space in a sealed state are formed. A surrounded space in a sealed state whose top and bottom are surrounded by a decorative film and the body to be coated in the decoration forming range is formed after the lower space and the upper space (A) in the sealed state are brought into a predetermined first pressure state where the pressures in the lower space and the upper space (A) are equal to each other. By instantaneously increasing the pressures in the lower space and the upper space (A) around the surrounded space from the pressure-reduced state to a second pressure state where the pressures are equal to each other while keeping the surrounded space at the first pressure state, partial decoration forming is performed on the decoration forming range in the surrounded space with the decorative film.

A DEVICE AND METHOD FOR MANUFACTURING RECEPTACLES PROVIDED WITH DECORATIVE WRAP-AROUND LABELS BY THERMOFORMING
20180169928 · 2018-06-21 · ·

The device includes a mold block having at least one thermoforming chamber (28) having an inside surface (29), an axial opening (28A) through which a decorative wrap-around label (38) can be inserted into the chamber, and a moving end-wall (40) opposite from the opening. The end-wall is suitable for moving in an end segment (28A) of the chamber (28) between a positioning high level and at least one thermoforming low level, and the device has at least one tongue-and-groove set comprising a fin (42) on the end-wall (40) that is engaged in a notch (44) in the inside surface of the end segment (28B).

Partial vacuum forming method by partial overlay of decorative film
09889601 · 2018-02-13 · ·

An upper opening accommodating chamber and a lower opening upper box are joined vertically together with a decorative film sandwiched therebetween to sealingly form a forming space in which the accommodating spaces and are coupled together, and each of the upper and the lower spaces of the forming space is pressure-controlled to bring, under reduced pressure, the decorative film into close contact with a surface of a part of the adherend accommodated in the forming space. The accommodating chamber includes a recessed receiving jig enclosing a predetermined forming portion of the entire adherend from the inside of the portion to a side periphery, and only the portion surrounded by the receiving jig is partially vacuum formed.

Molding method and molding device

A shaping method and a shaping device are provided which can easily and inexpensively form a curved face in a film including a micropattern. A shaping method is for forming, in a predetermined shaping-target area of a film including a patterned face with a micropattern, and a rear face opposite to the patterned face, a curved face beyond the thickness of the film, and includes a fixing step for fixing an outer edge of the shaping-target area of the film by fixing means, a first heating step for heating the film 20 by heating means 95, and a pressure adjusting step for producing a predetermined pressure difference between both faces of the film by the pressurizing means in such a way that pressure at a side where the film is fixed in the fixing step becomes small to form a pre-curved face.
