A runner system for a multi-cavity injection molding system, the runner system having runners of reduced size.

A hot-runner molding apparatus includes a hot-runner nozzle, a hot-runner molding die and a runner unit. The positions of outflow hole portions are arranged rotationally-symmetrical with respect to the positions of the runner groove portions in such a manner that the molten resin is equally distributed from a gate hole portion to the runner groove portions.

A spacer (1) is injection molded by using an injection molding die having resin flow channels that are designed such that a plurality of gates (6) are arranged along the longitudinal direction at a position corresponding to the outer peripheral surface of a side wall part (4) in which a plurality of arc-like peripheral surface parts (2) are connected through a waist part (3). After opening the mold and ejecting the spacer, the spacer is cooled with a runner (7) being connected to the gate (6), and thereafter, the runner (7) is cut off. As a result, when producing a water jacket spacer that is assembled to the inside of the water jacket and controls the flow of cooling water by injection molding, while producing with a high productivity without being affected by design constraints caused by draft angle, deformation in the post-molding cooling step is prevented.

Articles of manufacture, systems, and methods for arranging and securing a plurality of components used to assemble a product are provided. A component tree may include a plurality of components. The plurality of components may include an interlocking tee, a top cap, an adjustable foot, a foot adjuster and a wall bracket. A plurality of connecting means configured to couple each component of the plurality of components to an adjacent component of the plurality of components may be included. The plurality of components may be sequentially positioned along a length of the component tree in a predetermined order.
