摘要

A mold assembly for injection molding an article includes a first mold part having a first inner surface of the mold having a configuration corresponding to the configuration of the first surface of the article. A first array of first pins extends from the first inner surface through the mold cavity when the mold assembly is closed. A second mold part has a second inner surface of the mold having a configuration corresponding to the configuration of the second surface of the article. The second mold part has a second array of second pins extending from the second inner surface and only partially into the mold cavity. The article is preferably molded with a low viscosity, high temperature material, such as a liquid crystal polymer.
