TRIM TOOL WITH ADJUSTABLE TRIM CENTERS
20230051517 · 2023-02-16 ·

A thermoforming trim tool which comprises a punch side and a die side. The punch side moves to the die side in order to trim molded articles from a heated thermoforming sheet that is disposed therebetween. While the punch side of the tool comprises a plurality of punches, the die side of the tool comprises a plurality of dies, and both the punches and the dies are engaged with upper mount plates. Each of the upper mount plates is engaged with a lower mount plate via one or more location keys. Each of the location keys is configured to provide that the upper mount plates are shifted a pre-determined distance relative to the lower mount plate, thereby providing trim centers which are adjusted to account for pre-determined shrinkage in the sheet.

Continuous press-molding method and heating machine therefor
11548203 · 2023-01-10 · ·

A strip-shape softened resin sheet (S) which is continuously extruded from a molten resin extruder is cut to a unit resin sheet and a press molded product is manufactured by press-molding the unit resin sheet in a press-molding machine 20. Prior to press-molding the unit resin sheet (U) by the press-molding machine, the unit resin sheet (U) is heated by a heating machine 16. The heating machine 16 comprises a first heating furnace 84 and a second heating furnace 86. The first heating furnace 84 includes a series of heaters 84-3 and 84-4 whose heat source is infrared ray in a far-infrared region and the second heating furnace 86 includes a series of heaters 86-3 and 86-4 whose heat source is the infrared ray in a middle-infrared region. In the first furnace 84, the unit resin sheet (U) is continuously conveyed with a low velocity and is gradually heated by the far-infrared ray up to temperature which is slightly lower than the temperature which is suitable for press-molding the unit resin sheet (U). In the second furnace 86, the unit resin sheet (U) is stopped and is rapidly heated by the middle-infrared ray. By efficiently heating the unit resin sheet (U), a cycle time can be shortened and the production speed can be improved.

Method of thermoforming a foil, forming tool, thermoforming tool, installation for thermoforming, container and brewing container

Method of forming, in particular a thermoforming method, a foil into a container, in particular a brewing container, especially a coffee capsule, using a plug assist and/or pressure difference in axial main forming direction, directing the foil into a forming tool creating a blank with a cavity and pressing the foil towards the forming tool bottom in order to create a floor for the blank and characterising the method in that the floor of the blank experiences a material distribution, especially a material shifting and/or material compression, during which a constant pressure difference within the blank's cavity is guaranteed and a circumferential annular gap is created.
