PYLON SNAP JACKET ENCASEMENT
The present invention provides a protective coating for protecting a substrate from deleterious elements present in environments in which the substrates are deployed and methods and apparatus for deploying a PVC encasement with a longitudinal snap jacket of suitable length and girth to coat a pylon substrate or building girder and provide a filler within the snap jacket and around an encased pylon.
METHOD AND APPARATUS FOR MAKING A CONTAINER COMPRISING A TRAY INTERNALLY COVERED WITH A LAYER OF THERMOPLASTIC MATERIAL
A method for making a container, wherein in a positioning step a tray (2) constituted of a single sheet of material, folded and shaped with wrinkled zones (3) is positioned in a thermoforming mould (7), and wherein in a covering step a sheet of thermoplastic material (1) is thermoformed on the tray (2), the covering step being carried out while preventing the thermoforming mould (7) from making contact with the layer of thermoplastic material (9) at the wrinkled zones (3) of an annular flange (6) of the tray (2). Also claimed is an apparatus (13) which comprises a thermoforming mould (7) in which there are present a first peripheral portion (8) configured to support in use the annular flange (6) of the tray (2) and a second peripheral portion (17) which, in the operating position, is facing the first peripheral portion (8), wherein in the operating position, the second peripheral portion (17) is at a distance from the first peripheral portion (8) in such a way that it does not make contact with the layer of thermoplastic material (9) stuck to the tray (2), at the wrinkled zones (3) of the annular flange (6).
Process for producing shaped film
The method of the present invention for producing a shaped film includes a step of arranging a thermoplastic resin film to divide a space into a first space located on one surface side of the film, and a second space located on the other surface side, a step of heating the thermoplastic resin film, a step of curving the thermoplastic resin film in one space by using a difference in pressure between the first space and the second space, a step of stopping the curving step of the thermoplastic resin film in a state where at least a convex curved surface of both surfaces of the film is exposed into the space, and a step of cooling the curved film.
Pressure Forming Machine
A pressure forming machine is provided. In one embodiment, the pressure forming machine integrates a heater in its pressure chamber, so the heater and pressure chamber are movable together with respect to a base of the pressure forming machine. The pressure chamber and base can contain locking mechanisms to create a seal between the pressure chamber and a plastic sheet used for forming. The base can also contain a separable air compressor component, so the air compressor can be physically distanced to reduce the noise experienced by a user. Other embodiments are provided.
Biodegradable and Industrially Compostable Injection Molded Microcellular Flexible Foams, and a Method of Manufacturing the Same
A process for injection molded microcellular foaming various flexible foam compositions from biodegradable and industrially compostable bio-derived thermoplastic resins for use in, for example, footwear components, seating components, protective gear components, and watersport accessories wherein a process of manufacturing includes the steps of: producing a suitable thermoplastic biopolymer or biopolymer blend; injection molding the thermoplastic biopolymer or biopolymer blend into a suitable mold shape with inert nitrogen gas; controlling the polymer melt, pressure, temperature, and time such that a desirable flexible foam is formed; and utilizing gas counterpressure in the injection molding process to ensure the optimal foam structure with the least amount of cosmetic defects and little to no plastic skin on the outside of the foamed structure.
NESTABLE WATER TANK AND METHODS OF MANUFACTURING NESTABLE WATER TANKS
The present disclosure relates to a method for manufacturing a nestable water tank, the method comprising molding a water tank comprising a hollow cylindrical body and cutting the water tank to form the nestable water tank comprising a tank body and a lid, wherein the tank body comprises: a side wall comprising a cylindrical shape running along a vertical axis, an interior surface, and an exterior surface; and a bottom connected to a bottom portion of the cylindrical tank, together forming a nestable water tank interior space capable of storing water within the nestable water tank interior space and comprising an interior bottom surface and an exterior bottom surface, wherein at least one of the tank body and the lid are each nestable with other similarly shaped tank bodies and lids.
METHOD OF HANDLING A PLASTIC CONTAINER HAVING A MOVEABLE BASE
Method for processing hot-filled plastic containers are provided. In some embodiments, the method may include hot-filling a plastic container, sealing the container, and conveying the sealed container, each with an inner annular wall and a push-up portion in a first position. In some embodiments, the method may further include creating a vacuum pressure in the hot-filled and sealed container and repositioning the push-up portion from the first position to a second position under a mechanical force.
Molding tool and molding method for producing containers with undercuts
A molding tool (1000), in particular a thermoforming tool, for producing a container (10) is provided. The molding tool comprises a mold bottom (200) and a mold insert (100) receiving the mold bottom (200), wherein the mold insert (100) is constructed of at least two mold insert parts (110, 120) that together with the mold bottom (200) define a cavity (300) provided for reshaping a two-dimensional web of material into a container, wherein a first mold insert part (110) is mounted stationary in the molding tool (1000) and a second mold insert part is axially movable in the molding tool (1000).
PROCESS FOR MAKING A CONTAINER OF A GIVEN SHAPE FROM SHEET MATERIAL
Process for obtaining a container of a given shape starting from sheet material, by providing a sheet; providing a mould having a forming cavity, which defines a reference axis (R) and has a shape corresponding to the given shape of the container; positioning the sheet over forming cavity; providing a forming device having forming structure arranged on a side of the sheet opposite the forming cavity, and operating the structure for inserting the sheet into the forming cavity to deform it until a container blank is obtained having a shape approximating the given shape; and blowing a gas under pressure into the forming cavity to deform the container blank until the container with the given shape is obtained.
