摘要 |
The present invention provides an improved process for molding thermotropic liquid crystalline polymer, and the apparatus for such process. The process comprises the steps of providing a molten stream of the polymer to be molded; injecting the molten stream into the cavity of the mold; continuously allowing a portion of the melt to flow out of the cavity during the entire filling of the cavity so as to substantially preserve the laminar flow pattern of the melt in the cavity; and solidifying the molten polymer into a molded article. The resulting articles have mechanical properties superior to conventionally molded articles.
