Transfer printing apparatus and manufacturing method of light guiding film

A transfer printing apparatus includes a mold, a stamper, a pressing roller and a curing unit. The mold has a first surface with first and second concavities, the second concavity has first and second planes, the first plane is perpendicular to the first surface, and the second plane is inclined to the first surface. The stamper having a second surface is disposed in the first concavity. The first and second surfaces are coplanar, and the second surface has transfer printing microstructures. The first and second surfaces are suitable for coated an adhesive layer. The pressing roller presses a base film onto the adhesive layer, such that the adhesive layer is integrated with the base film. The curing unit cures the adhesive layer on the base film, such that a taper corresponding to the second concavity and optical microstructures corresponding to the transfer printing microstructures are formed on the adhesive layer.

FLAT-PRESSING MANUFACTURING METHOD OF BIONIC ADHESIVE STRUCTURE BASED ON MICRO THROUGH-HOLE NICKEL-BASED MOLD

A flat-pressing manufacturing method of a bionic adhesive structure based on a micro through-hole nickel-based mold is disclosed. The method includes the following steps: preparing a nickel-based mold with a micro through-hole array; placing the nickel-based mold on an elastic pad in a magnetic mold closing system; coating a liquid prepolymer uniformly on a backing, and placing a side of the backing coated with the liquid prepolymer on the nickel-based mold, covering a sealing diaphragm on the backing to separate a cavity into an upper chamber and a lower chamber, and performing a vacuum treatment on the lower chamber and an inflation treatment on the upper chamber to apply a uniform pressure on the backing layer and achieve a full filling of prepolymers with different viscosities; and after the filling is completed, curing and demolding to obtain the bionic adhesive structure.

METHOD FOR ADDITIVE MANUFACTURING

An additive elastomeric manufactured part having an elongation at break of at least 50% may be made by a method comprising the following. A material comprising a prepolymer and filler is first dispensed through a nozzle to form an extrudate deposited on a base. The base, nozzle or combination thereof is moved while dispensing the material so that there is horizontal displacement between the base and nozzle in a predetermined pattern to form an initial layer of the material on the base. Subsequent layers are then formed on the initial layer by repeating the dispensing and movement on top of the initial layer and layers that follow.

APPARATUS AND METHOD FOR CONTROLLED PELLETIZATION PROCESSING

An apparatus and process to maintain control of the temperature of low-melting compounds, high melt flow polymers, and thermally sensitive materials for the pelletization of such materials. The addition of a cooling extruder, and a second melt cooler if desired, in advance of the die plate provides for regulation of the thermal, shear, and rheological characteristics of narrow melting-range materials and polymeric mixtures, formulations, dispersions or solutions. The apparatus and process can then be highly regulated to produce consistent, uniform pellets of low moisture content for these otherwise difficult materials to pelletize.

DOUBLE-WALLED CONTAINER MANUFACTURING METHOD

The present invention is a double-walled container manufacturing method in which when a pair of partial molds is brought towards each other to be assembled to form a split mold, at least a portion of the mating surfaces of the pair of partial molds clamp a parison at two side portions that are at horizontal positions facing each other. The method is able to manufacture the container easily with a molding device that does not differ significantly from the past and, in a double-walled container obtained from a relatively rigid outer container and a flexible inner container the volume of which can change according to the amount of contents filled inside said outer container, an opening for introducing outside air can be formed very easily and reliably at a lower cost than the processing cost of prior art.

Disclosed is a method of manufacturing a thermoplastic synthetic resin product, including preparing a mold having a cavity formed in a predetermined shape; filling the cavity of the mold with a thermoplastic synthetic resin material in an amount greater than the volume of the cavity of the mold; heating the mold under pressure; releasing the pressure when the thermoplastic synthetic resin material charged in the cavity of the mold is melted by heating, and opening the mold; removing, of the melted thermoplastic synthetic resin material in the opened mold, the material other than the material charged in the cavity of the mold; placing either a fabric or a hot melt on the mold having the cavity filled with the thermoplastic synthetic resin material; and cooling the mold under pressure, thus integrating either the fabric or the hot melt with the thermoplastic synthetic resin material in contact with either the fabric or the hot melt.

Methods for dispensing and adhering hot melt entrained polymers to substrates

Disclosed are methods for forming and adhering an entrained polymer structure to a substrate. The methods include providing a substrate (114) configured to receive application of a molten entrained polymer (118). A mineral entrained polymer in molten form is applied in a predetermined shape, to a surface of the substrate, to form a solidified entrained polymer structure on the substrate. The entrained polymer includes a monolithic material formed of at least a base polymer (25) and a mineral active agent (30) to absorb excess moisture. The surface of the substrate is compatible with the molten entrained polymer so as to thermally bond with it. In this way, the entrained polymer bonds to the substrate and solidifies upon sufficient cooling of the entrained polymer. The polymer can have a channeling or foaming agent (35), eg polyglycol. To apply the polymer is provided a hot melt dispensing apparatus comprising: a feeder (102) (optionally an extruder or loader) for providing a flow of mineral entrained polymer in molten form; one or more hoses (104), each of which having an internal lumen in fluid communication with an exit (106) of the feeder to receive flow of the mineral entrained polymer in molten form, the lumen terminating at an applicator (110) to which the entrained polymer in molten form is conveyed; the applicator comprising a dispenser (112) for applying the entrained polymer in the predetermined shape to the surface of the substrate. The hose and the dispenser can be heated.
