摘要： An example system for molding a photocurable material into a planar object includes a first mold structure having a first mold surface, a second mold structure having a second mold surface, and one or more protrusions disposed along at least one of the first mold surface or the second mold surface. During operation, the system is configured to position the first and second mold structures such that the first and second mold surfaces face each other with the one or more protrusions contacting the opposite mold surface, and a volume having a total thickness variation (TTV) of 500 nm or less is defined between the first and second mold surfaces. The system is further configured to receive the photocurable material in the volume, and direct radiation at the one or more wavelengths into the volume.

摘要： The present invention lies in the field of the industrial manufacturing of cast parts and relates to an apparatus and method for the automated production of parts of this type having very fine surface structures, particularly concentrator lens panels, which contain at least one, preferably annular, stepped region as per Fresnel lenses. Handling during the production of the lens panels is difficult, inter alia, because after the curing operation, on account of relatively large adhesion forces or cohesion forces, the mould is removable in a precisely reproducible manner from the product or from the system only with difficulty. It is the object of the present invention to provide a method and an apparatus for the automated production of concentrator lens panels. This is achieved in that a die containing an upper plate (8) and a lower plate (1) initially holds the mould (6) in a precisely defined manner on the upper plate, and the deformable material mass (3) lying on a glass or plastics plate (2) rests in a precisely positioned manner on the lower plate, and then the upper and lower plates are moved together leaving an intermediate space which is evacuated, and the entire sandwich packet is then joined together, kept in a pressed manner and heated until the material is firm. Specially designed securing means (13) then ensure that the sandwich packet can be undone in a reproducible manner and the mould (6) can be separated from the product (9) in a defined manner.

摘要： A method of forming a liner for a passage such as a sewer includes forming panels composing the liner using a neat resin of a first density and a polymer concrete of a second, higher density. The neat resin is inserted into a mold cavity before the polymer concrete and is displaced upwardly by the polymer concrete pour to impregnate a fiber layer disposed along the periphery of the mold cavity. Resulting panels preferably have an offset joint to increase the joint strength between upper and lower panels forming the liner.

摘要： A mold apparatus and method for manufacturing panels having, as desired, one or more areas of reduced material comprising a facing sheet and integrally attached cell forming walls extending in roughly perpendicular fashion from the facing sheet. Additionally, a method for molding panels, including large scale panels, from thermoplastic resins and other moldable materials requiring significantly less energy than other known molding methods, and providing for panels having one or more areas exhibiting continuous outer surfaces on all dimensions. A lower negative mold member has a plurality of upwardly facing positive standoffs defining interstitial channels into which thermoplastic resin or other moldable material is filled. A generally planar upper mold member is placed on the lower mold, and the combined mold assembly is then subjected to elevated heat and pressure, allowing said thermoplastic resin or other moldable material to melt within the interstitial spaces of the lower mold member. After cooling, upper and lower mold members are separated, and a molded panel structure is removed therefrom.

摘要： A thermoplastic mold for creating large sheets of building materials from recycled plastic. The mold is adapted to be used with a platen press, and has an adjustment feature for defining a mold cavity of a selected thickness. A pair of shims are preferably used to establish the mold cavity, wherein the cavity has a depth identical to the thickness of the shims. The top member or lid of the mold has an integrally defined passageway for allowing a cooling fluid to be circulated therethrough to cool the mold after a molding process. In the one embodiment, the lid has a pair of flanges extending over and engaging the shims, and an alternative embodiment the lid comprises a rectangular plate having handles defined at selected locations in the upper surface for facilitating removal of the lid from a mold recess. The sheets can be colored on one or both sides by inserting a thin sheet of colored thermoplastic material in the mold prior to pressing.

摘要： A process for producing a resin molding having a concave-convex pattern on the surface includes the steps of providing an original die having a concave-convex pattern on the surface and a substrate having a flat surface, thereby counterposing the concave-convex pattern surface and the flat surface to each other through a spacer and forming a cell with a cavity formed by the original die, the substrate and the spacer; making an internal pressure of the cell cavity lower than an external pressure thereof, thereby filling at least one of a liquid polymerizable component and a liquid resin into the cavity due to a pressure difference between the external pressure and the internal pressure; curing at least one of the polymerizable component and the liquid resin in the cavity, thereby making a replica; and peeling the original die from the replica, thereby obtaining a resin molding.
