Deep-drawing hollow objects, especially containers having large bodies and smaller necks

This novel method forms hollow objects, especially containers, by deep drawing. The feedstock is an individual- or sheet blank material (2). This is softened above the matrix containing the mould chamber (15) corresponding to the final shape. Force is exerted on the blank, to press it into and against the walls of the mould chamber. The novel feature of this process is an initial preforming stage. The plasticised blank is made into a cup-, pouch- and/or tub-shaped preform (10). Maximum expansion, parallel to the base, is limited to allow introduction of the preform into the mould chamber. Also claimed are the equipment required for the process and the corresponding preforming tool. Preferably the preform is long and its width is less than the minimum, open internal width (26) of the moulding chamber. Before preforming, a intermediate preform is produced. This tapers to the base region (57), having a pouch-, cup-, hollow conical- or other similar shape. The preforming tool (4) brings the ...

TITLE PROCESS FOR THERMOFORMING REINFORCED POLYMER SHEETS Reinforced poly(ethylene terephthalate) sheets are thermoformed to articles having one or more surfaces in contact with the mold of such a degree of smoothness that they virtually completely replicate the mold face. When the mold face is completely smooth, the concave imperfections caused by air entrapment in the plastic material account for less than 6% of the surface area. Composite articles consisting of a face member and a backing member are made by thermoforming in a single mold a face member having one or more surfaces in contact with the mold face of such a degree of smoothness that it completely replicates the mold face, and its proportion of concave imperfections is less than about 6% of the surface area. The backing member is bonded in the mold with an adhesive to the face member, and the composite structure is allowed to remain in the mold for a sufficient time to permit subsequent removal without distortion.

Plastic packaging containers prodn

Packaging containers are produced by deep drawing heated plastic film, which has at the beginning of shaping a different temp. at different positions in order to alter the extensibility of the film. The temp. of the film parts which are extended most during deep drawing is lower than the other parts. When the temp. of the film parts which are subjected to the greatest extension during deep drawing, is less than that at the other parts, then the reduction in wall strength of these parts is less than for a uniformly heated film. Consequently the container has a more uniform wall strength.

Vacuum transfer moulding station and process for heating a plastics film, especially for manufacturing a casting mould moulded under vacuum

The invention can be used for vacuum processes and generally in the heating of plastics films. Whilst the aim can be seen as reducing the energy input and as reducing heating times and as avoiding quality defects, the object consists in achieving a uniform direct heating of the plastics film depending on the film grade used with simultaneous measurement of the film temperature, with an application being permitted even for highly contoured designs. This is substantially achieved by designing the film heating device as a controllable height-adjustable contact heater, the heating surface being air- permeable and having an anti-adhesive coating on its underside. The contact heater is surrounded by a housing provided with a thermal insulation, on which a connection is provided for a vacuum source. A metal plate of air-permeable design is provided as heating surface, on the uncoated surface of which heating elements and temperature sensors as well as a reflector covering these are disposed. <IMAGE>

Apparatus for thermoforming a foil

Process and device for producing a flowable product package via a shell

Process and Device for Producing a Flowable Product Package Via a Shell In a method for manufacturing a half-shell from thermoplastic material, a plate-shaped section, to be worked, of the plastics material (40) is transported downwards on a vertical web (21) through at least two heating stages (45), arranged one behind the other in the direction of movement (21, 24) to a deep-drawing station (16, 24) and subsequently deep-drawn. In order that the heating of the plastics material prior to deep-drawing can be done more easily and reliably from a technical point of view, it is proposed according to the invention that the plastics material is supplied in the form ofa continuous web (40) from above the first heating stage (45), with heating of the web sections during the movement, vertically downwards to the deep-drawing station (24), on the top end (46) of which the frontmost, lowest plate-shaped section is separated (by 47) during deep-drawing and is deep-drawn.

Vertical path ovens for preheating continuous sheet - approaching thermo-forming press, for ease of removal of volatiles and control of sheet face temp. differentials

An oven for preheating continuous thermoplastic sheet prior to thermoforming the sheet with plunger assistance comprises a tower adjacent the forming press and through which the sheet passes up and down vertical paths while subjected to heat from between the two film paths. The heating pattern ensures that the underside of the film entering a conventional forming tool (base cavity, overhead plunger) is as hot or hotter than the upper face, so that (a) the moulding will adhere better to the mould than the plunger, (b) the underside can be hot enough to bond with mould inserts, e.g. labels without overheating the upper surface. The vertical oven requires relatively little floor space alongside a forming tool, and a chimney effect can be used to facilitate removal of volatiles more efficiently than from a long horizontal oven. The vertical sheet paths avoids risk associated with horizontal ovens of sheet sagging away from or towards horizontal banks of heaters.
