Abstract: A below grade trench drain system and a method for making the trench drain system is disclosed which does not rely on the contractor's prowess to dig a trench with a proper slope. The trench drain system, in accordance with the present invention, includes a plurality of modular trench sections formed with a uniform exterior height and an interior fluid channel formed with a pre-sloped floor. As such, the trench drain system, in accordance with the present invention, can be installed in a level trench, which greatly simplifies installation by the contractor and ensures that the trench drain will be installed with the proper slope. The modular trench sections can be coupled together forming a trench drain with a continuous slope or alternatively coupled with modular trench sections with no slope to form a stepped slope.

Abstract: 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.
