  • Publication number: 20150021827
    Abstract: The present invention relates to a method and a device for producing a preform with a base geometry optimized for the subsequent stretch blow molding. The preform produced in the injection mold is removed in a cooled removal sleeve and cooled in the shaft by intensive contact cooling, while to the greatest extent no cooling contact is made with the domed preform end due to a special contour of the cooling sleeve. On account of the re-heating of this domed end that is possible as a result, the latter can be mechanically deformed into a new geometry that is more advantageous for the blow-molding process, and consequently also influenced in the wall thickness. In the subsequent blow-molding process, such a deformed preform has primarily the advantage that the polymer material distributed better in the bottle can lead to considerable material savings and to bottle bases of a higher quality.

  • Patent number: 8852487
    Abstract: A method for injection molding a thermoplastic composition that contains a polyarylene sulfide and a boron-containing nucleating agent is provided. By selectively controlling certain aspects of the polyarylene sulfide and nucleating agent, as well as the particular manner in which they are combined, the crystallization properties of the resulting thermoplastic composition can be significantly improved.

  • Patent number: 8790763
    Abstract: The present invention discloses a thermoplastic polyurethane which is comprised of the reaction product of (1) a hydroxyl terminated polyester intermediate, (2) a polyisocyanate, and (3) a glycol chain extender; wherein the hydroxyl terminated polyester intermediate is comprised of repeat units that are derived from 1,3-propylene glycol and a dicarboxylic acid; wherein the hydroxyl terminated polyester intermediate has a number average molecular weight from 500 to 10,000; and wherein the thermoplastic polyurethane includes hard segments that are the reaction product of the polyisocyanate and the glycol chain extender. This thermoplastic polyurethane is unique in that it has a greatly reduced tendency to bloom. This is highly desirable in applications where high clarity is desired because blooming causes articles containing the thermoplastic polyurethane to be hazy or foggy in appearance.

  • Patent number: 8709325
    Abstract: The molding method of the invention is a low-temperature, liquid-phase, injection molding process using an externally heated mold. This molding process is ideally suited for production of limited quantities of molded parts, as comparatively low cost molds can be used. The molding composition used in the invention is a mixture of a carrier and binder component and a powdered polyethylene component. The carrier and binder component can be a very low density polyethylene, petroleum jelly, hydrocarbon waxes, liquid hydrocarbon oils, or mixtures thereof. The powdered polyethylene component is finely subdivided polyethylene, preferably ultra high molecular weight, having a low melt index, at least no greater than 30. The carrier and binder component is used in sufficient quantity to provide a thixotropic mixture with a consistency of toothpaste, typically having a stirred viscosity up to 30,000 centipoise at the injection temperature of the molding process.
