摘要： Improved dip coating methods and mandrels for forming polymer leaflets and valve prostheses are disclosed. The mandrel (300,324,350) has a top surface and an outer surface comprising a plurality of ridges (306,402) and contoured surfaces extending to the ridges. An edge (312) on the mandrel separates the top surface and the contoured surfaces, with the mandrel edge corresponding to the free edge of the leaflet. In preferred embodiments, the edge separating the top surface from the contoured surfaces is sharp. The polymer formed on the top surface can be efficiently separated from the remaining portions of the polymer structure to form the free edges of the leaflets.

摘要： An apparatus (10) for slush molding a thin shell having an outer layer and an inner layer. The apparatus includes two tubs (14,16) alternately movable to a cast position for dispensing their respective material contents (24, 26) into a mold cavity (28). According to another embodiment of the invention, the apparatus includes a diverter valve configured to alternately open a passage from each of two tubs (14, 16) to the mold cavity to selectively dispense charge materials from the respective tubs into the mold cavity (28). In addition, a method is provided for forming a thin shell having an outer layer and an inner layer. A first polymer material is cast and allowed to melt on a heated mold surface (31) to form an outer layer. A second polymer material is then cast and allowed to melt and form an inner layer on the inner surface of the outer layer. The shell is then removed from the mold.

摘要： This invention discloses a process for applying a rubbery coating to a substrate which comprises: (1) dipping the substrate into a plastisol composition in a manner whereby the plastisol composition is applied to the surface of the substrate, wherein the plastisol composition is comprised of (i) polyvinyl chloride, (ii) from about 70 to about 100 parts of a plasticizer per 100 parts of the polyvinylchloride, (iii) from about 1 to about 3 parts of a stabilizer and (iv) from about 10 to about 30 parts of a highly crosslinked nitrile rubber composition per 100 parts of the polyvinyl chloride, wherein the highly crosslinked nitrile rubber has repeat units which are derived from (a) 1,3-butadiene, (b) acrylonitrile and (c) a crosslinking agent, and wherein said highly crosslinked nitrile rubber has a Mooney viscosity of about 50 to about 120, a swelling index of less than about 10 percent, a mill shrinkage of less than 10 percent and a gel content of greater than 90 percent; (2) removing the substrate from the plastisol composition to produce a plastisol coated substrate; (3) heating the plastisol-coated substrate to a temperature which is within the range of about 150°C to about 200°C for a period which is sufficient to fuse the plastisol composition to the substrate producing a rubber-coated substrate. The highly crosslinked rubber compositions of this invention can be utilized in slush molding applications.

摘要： A mixture of vinyl plastisol, suspension grade resin and expanded perlite is prepared in a manner such that the particles of perlite are not significantly damaged. The mixture is placed on a substrate and fused, thereby producing a foam-like material which is usable as a decorative covering. Alternatively, the mixture can be cast on a release surface and allowed to stand until the majority of the perlite particles have migrated to the top surface, thus leaving a layer of material containing substantially no perlite along the lower surface which interfaces with the release surface. Upon fusing this stratified mixture and separating the release surface, the fused material is inverted. The layer of material which contains substantially no perlite becomes the protective surface and the remaining portion of the fused material, which is foam-like in nature, becomes the resilient support. Such syntactic foams may be used as replacements or substitutes for mechanically frothed or chemically blown foams.

摘要： An assembly (10) for molding a two-tone, thin-walled plastic shell (12) for parts such as automobile door panels, control and instrument panels and the like includes a charge box (24) for supplying dry thermoplastic material to separate casting surfaces (30, 32) on a heated mold (22) selectively connected to the charge box (24) during the casting process. A pressurized inflatable seal gasket (60) is connected to the charge box (24) for sealing a division surface (36) on the heated mold (22) which surface (36) separates the casting surfaces (30, 32) of the mold (22). The seal gasket (60) is attached to the charge box (24) on a divider wall (42) via a sliding member (80) which positions the seal gasket (60) longitudinally along the divider wall (42). The sliding member (80) is secured to the divider wall (42) via threaded pins (86). The gasket seal (60) may be removed and reinserted in the slider member (80) providing automatic adjustment thereof.
