Method And Plant For The Production Of A Casing For A Solid-Propellant Engine, And Casing Made According To Said Method

Номер: US20120042629A1

Автор: Giuseppe Magistrale

Принадлежит: Avio SpA

A casing of a solid-propellant engine comprising a core and a layer of elastomeric material, set as coating for at least part of the core to provide a thermal protection of the core itself is obtained by: inserting the core in a forming mould so as to make within the mould two annular chambers separated from one another by the core; forming a strand of elastomeric material; obtaining a defined portion of elastomeric material by cutting the strand transversely to size in an external environment; and injecting the cut portion of elastomeric material simultaneously within both of the annular chambers.

Elastomeric Compositions Comprising Reclaimed Vulcanized Elastomer Particles of Broad Size Distribution and Chemically Modified Vulcanized Elastomer Particles

Номер: US20120316283A1

Автор: Charles Rosenmayer, Frank Papp

Принадлежит: Individual

Elastomer compositions comprising uncured elastomer and reclaimed elastomer are described. In one embodiment, the compositions comprise reclaimed elastomer material (micronized rubber powder) of broad particle size distribution, which is less expensive than traditional reclaimed elastomer material with narrow particle size distribution. Further, compositions comprising reclaimed elastomer materials with broad particle size distribution perform comparably to those comprising reclaimed elastomer materials with narrow particle size distribution. In other embodiments, the compositions comprise both vulcanized and devulcanized elastomer materials. Advantageously, by using a combination of vulcanized and devulcanized material, it is possible to incorporate a greater percentage by weight of reclaimed material in to an elastomer composition, thus providing additional cost savings while maintaining high levels of mechanical properties. Further, the use of the reclaimed material reduces landfill waste resulting in a more environmentally friendly product.

METHOD FOR MANUFACTURING IMITATION WOOD

Номер: US20170036405A1

Автор: TSAI TZU-LIANG

Принадлежит: YEA DER LIH ENTERPISE CO., LTD.

The present invention provides a method for manufacturing an imitation wood and is featured by adjusting the temperature of a discharge outlet before or during conveyance of thermoplastic elastomers in a helical section of a screw extruder to be lower than the temperature of a tail end of the helical section, such that the viscosity of the thermoplastic elastomers in the discharge outlet increases and the flow velocity reduces at the outlet during the discharge process at the discharge outlet. Thus, the thermoplastic elastomers flow in a direction opposite to the discharge direction and rub, resulting in marks of back-flow and rubbing. During the process of back-flow and rubbing, the plastics will be pulled and break along the rubber elastomers and become filament-like, thereby generating filaments similar to wood. Then, the foaming blank material is squeezed out of the discharge outlet and is forced into a molding machine to proceed with planarity trimming, and the output material is cooled with a preset cold-bath tank of the molding machine, providing adjustment of different densities of imitation wood, such that the imitation wood produced by the present invention has high simulation of wood. 1. A method for manufacturing imitation wood , characterized by including at least the following steps of:(1) providing a screw extruder including a feeding hopper and an extrusion head respectively at two ends thereof, with the extrusion head connected to a discharge outlet, and with a helical section located between the feeding hopper and the extrusion head;(2) feeding thermoplastic elastomers into the helical section through the feeding hopper, and conveying the thermoplastic elastomers in the helical section;(3) adjusting the temperature of the discharge outlet before or during conveyance to be lower than the temperature of a tail end of the helical section, wherein the viscosity of the thermoplastic elastomers increases and the flow velocity reduces at the outlet during ...

In a method of manufacturing a seal assembly, strips of material are extruded to form first and second bodies, and ends of the bodies are positioned into a mold cavity of a molding apparatus. An elastomeric material is injected into the mold cavity to form a locator device having a foot portion and a tab portion with the tab portion defining a first reference point. A thermoplastic elastomeric material is injected into the mold cavity to form a corner mold covering the body ends and the foot portion of the locator device with the corner mold defining a second reference point. The corner mold bonds the first body end, the second body end, and the locator device together to fix the locator device to the first body end at a locator position such that a predetermined distance between the reference points is maintained during injecting of the thermoplastic elastomeric material.
