TRIM TOOL WITH ADJUSTABLE TRIM CENTERS
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.
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.
Method for producing a cup for a capsule for infused or soluble beverages, and related cup and capsule
A method for producing a cup for a capsule for the preparation of infused or soluble beverages is provided. The method includes the steps of co-injection molding a cup of multilayer plastic material with an intermediate layer of the gas barrier type, the cup being a single body provided with a bottom having a nozzle, and an inner base including a completely closed central portion covering the nozzle, partially cutting the central portion to form at least one opening connecting the inside of the cup and the nozzle, and a further step of folding a portion of the cup between the opening and the nozzle towards the inside of the nozzle to form a deflector.
Recyclable, high barrier sheet and tray
An improved sheet for making a three-dimensional article for holding food, such as a food tray, and a method of making a three-dimensional article. The sheet comprises a substrate and a laminate film. The laminate film may comprise a ceramic film and a copolymer layer. The copolymer layer can repair any cracks that occur in the ceramic film when the sheet is thermoformed. The food tray is considered a single material that is recyclable.
Method for producing a foamed granulate and use thereof
The invention relates to a method in which a polyester melt containing one or more polyesters is produced, the polyester melt being foamed by a blowing agent and a foamed granulate is produced from the foamed polyester melt. The intrinsic viscosity (IV) of the polyester melt is reduced by the blowing agent about at least 0.05 dl/g, measured according to ASTM D4603, and the IV of the foamed granulate is then increased by means of a solid phase polycondensation (SSP).
APPARATUS FOR MAKING A CONTAINER
An apparatus for making a container (2) which comprises an outer skeleton (6), which includes at least one first sheet (8) and one second sheet (9), and a layer of thermoplastic material (7) the apparatus (1) comprising a conveying element (15) which defines a housing (22), which is mounted on a supporting structure (11) and which is movable along a movement path (16) which extends from an infeed station (17) to an outfeed station (18), along the movement path (16) the apparatus (1) having a first feeding station (19), a second feeding station (20), and a thermoforming station (21) placed downstream of the feeding stations, the apparatus also comprising a first feeding device (23) at the first feeding station (19) and configured to insert the first sheet (8) into the housing (22), a second feeding device (24) at the second feeding station (20) and configured to insert the second sheet (9) into the housing (22), and a thermoforming device (31) at the thermoforming station (21) and configured to thermoform a thermoplastic material (10) on the first sheet (8) and on the second sheet (9).
Method of forming an article
Methods of forming an article from a molten plastic composition comprising a polymer and a blowing agent. The methods include injecting the molten plastic composition into a mould, allowing the plastic composition to form a first solid skin adjacent to an in contact with a first cavity-forming surface of the mould and a second solid skin adjacent to and in contact with a second cavity-forming surface of the mould, and then opening the mould before the molten plastic composition between the first and second solid skins in at least one portion of the circumference of a region of the mould cavity defining an annular cross-section of the cavity has solidified.
Station for thermoforming thermoplastic sheet-like blanks for thermoforming lines and a corresponding method
A station for feeding closing seals for containers, which includes at least one fixed magazine of seals which is provided with an outlet from which the seals can be taken individually. The station includes a carousel for feeding seals which can rotate with respect to a first central rotation axis and is provided with pickers which are radially spaced apart from the first rotation axis. The pickers are individually rotatable about a second rotation axis which is not parallel to the first axis of the carousel. During the rotation of the carousel, at least one picker can is configured to rotate about the second axis from a position for taking the seal from the magazine to a position for releasing the seal.
Blow molding method, blow molding mold, and blow molding apparatus
A blow mold method for a double-walled container, including: blowing in which an intermediate molded article is molded by stretch blowing a preform housed in a die; and pressing in which the intermediate molded article is pressed inside the die and a double-walled container is molded. During the pressing, an internal floor-corresponding section is pressed such that internal wall-corresponding section is inverted as far as the inside of an outer wall-corresponding section, in a state in which heat retention is maintained such that the internal wall-corresponding section can be inverted as far as the inside of the outer wall-corresponding section.
INJECTION MOLDING MOLD, INJECTION STRETCH BLOW MOLDING MACHINE, AND METHOD FOR PRODUCING HOLLOW MOLDED BODY
When a hollow molded body using a preform to be molded with a thin bottom portion is produced while taking advantage of the roughening of the outer surface of an injection core mold, transferred roughening marks are prevented from appearing on the bottom portion of hollow molded bodies, so that the hollow molded body with an aesthetic bottom portion is obtained. An injection core mold (12) has an outer surface of its tip portion corresponding to a preform bottom portion (10) and a lower end portion (14a) of a preform body portion (14). The outer surface corresponding to the preform bottom portion (10) and the lower end portion (14a) of the preform body portion (14) is a mirror-finished surface (20), and the outer surface of the injection core mold for forming the preform other than the mirror-finished surface is a roughened surface (15).
