1. A method for manufacturing a storage container with an injection molding process, the method comprising steps of:
providing a mold having a top wall, a bottom wall, and a plurality of side surfaces, the plurality of side surfaces includes a first side surface, a second side surface, a third side surface, and a fourth side surface, the mold includes two sections, wherein when the mold is in a closed position, a cavity is formed between the two sections, the mold further includes a plurality of injectors directed into the cavity when the mold is in the closed position, the plurality of injectors including at least one bottom injector disposed through the bottom wall and a plurality of side injectors disposed through at least one of the plurality of side surfaces, the plurality of side injectors including a first pair of side injectors disposed through the first side surface and a second pair of side injectors disposed through the second side surface;
providing a molten material;
positioning the at least one bottom injector along the bottom wall and the plurality of side injectors along at least one of the plurality of side surfaces at a desired height and a desired lateral position to achieve a balanced fill of the cavity;
injecting the molten material through the plurality of injectors disposed through each of the bottom wall and the at least one of the plurality of side surfaces of the mold into the cavity; and
removing the storage container manufactured with the injection molding process from the mold.
