A MOULD SET FOR FABRICATION OF AN EPS PALLET AND USE THEREOF
The present invention provides for a mould set for fabrication of an EPS pallet, a process for making the mould set for fabrication of the EPS pallet, and a process for fabricating the EPS pallet using the mould set. The mould set includes a modular platform mould and a leg mould configured to fabricate a platform section and plurality of leg support sections of the EPS pallet, respectively. The modular platform mould includes a modularity unit which enables alternation of dimension of hollow space which is configured to receive feed of polystyrene beads and thereby enabling moulding of the platform section of varying dimensions from a single mould. The one or more leg support sections are affixed to bottom side of the platform section at predefined locations, based on weight bearing capacity and position of lifting, to form the EPS pallet. The easy customization into various sizes as per requirement using a single mould structure reduces requirement of hoarding various moulds for different dimensions of EPS pallet, thereby significantly reducing the cost of moulding operations.
Pouch forming apparatus and method
To solve the above problem, a pouch forming apparatus according to an embodiment of the present invention includes: a die in which a forming space is recessed inward from a top surface thereof; a partition wall partitioning the forming space into first and second forming spaces; a stripper disposed above the die and configured to descend to contact the die with the pouch film therebetween to fix the pouch film to be seated on a top surface of the die; and an electromagnetic force generation part disposed above the forming space and configured to generate electromagnetic force and configured to apply the electromagnetic force to the forming space.

THERMOFORMING DEVICE, MOLD ASSEMBLY, MOLD, AND METHOD
A thermoforming device is described. It relates to a mold assembly including a first and second mold, and to a mold that can be used in a thermoforming device. It also relates to a method for thermoforming a product. The thermoforming device is characterized in that the thermoforming device comprises a second pre-stretcher, in addition to a first pre-stretcher and a calibration element, and that the second pre-stretcher is at least partially and moveably arranged in a second mold body. A movement relative to the second mold body and towards the same forming cavity of the first pre-stretcher, the second pre-stretcher, and the calibration element, can be individually controlled, and the second pre-stretcher at least partially surrounds the first pre-stretcher and the calibration element.

Pouch-Shaped Battery Case Shaping Apparatus Including Volatile Lubricant Supply Unit and Method Using the Same
A pouch-shaped battery case shaping apparatus includes a die having an open recess sized to correspond to an electrode assembly, a punch configured to draw a sheet into the open recess and thereby shape the sheet, a holder configured to fix ends of the sheet to the die during drawing of the sheet, and a lubricant supply unit configured to supply a lubricant to the sheet to minimize surface damage to the sheet due to the drawing of the sheet. A pouch-shaped battery case manufacturing process uses the pouch-shaped battery case shaping apparatus to shape the sheet.
Method of making a half shell
A method for producing a half-shell that includes an insert member for a high-pressure vessel using a mould having a first mould section forming a female mould. The method includes laying a pre-heated first plastic sheet on the first mould section; pressing or adhering, via one or more of a partial vacuum or a pressure, the first plastic sheet onto the first mould section; positioning the plastic of the first plastic sheet in areas behind a back-taper of the insert member at a lateral distance from the insert member, or positioning the insert member, after the pressing or adhering, so that plastic of the first plastic sheet is disposed in areas behind a back-taper of the insert member at a lateral distance from the insert member; and pressing or adhering, via a slide, partial vacuum, or pressure, the plastic of the first plastic sheet behind the back-taper and laterally distanced from the insert member, onto the insert member so that a space behind the back-taper of the insert member is filled with the plastic.
Frame device and method for thermoforming objects
A frame device for retaining and positioning sheet materials and possible reinforcing materials intended to be thermoformed to obtain objects made of composite material includes a first tubular element defining internally a first vacuum chamber for grasping by aspiration a first sheet material and a second tubular element defining internally a second vacuum chamber, separate from, and independent of the first vacuum chamber and configured for grasping by aspiration a second sheet material. The first tubular element and the second tubular element are fixed together permanently so as to define a grasping frame-structure configured as a single piece. A third vacuum chamber is defined in the grasping frame structure, separate and independent of the first and second vacuum chambers and configured for removing air from the zone that is interposed between the first and second sheet materials and which is intended for being possibly occupied by the reinforcing materials.

Reclosable package as well as thermoform packaging machine and method
A reclosable package, and a machine and method for making that reclosable package that includes a tray for receiving a product and a substantially horizontal edge, wherein the horizontal edge extends circumferentially on an upper side of the tray and has a clamping portion releasably connected thereto. The package includes a top film across the tray, the edge and the clamping portion, and which may be releasably connected to the edge by a first sealed seam to seal the tray in a gas-tight manner. The top film may be connected to the clamping portion by a second sealed seam. A side face of the tray may include an undercut provided with a projection, the projection being suitable for locking the clamping portion in position when the clamping portion has been detached from the edge and is located between the projection of the undercut and the side face of the tray.
