Abstract: A method of molding an interior part for a vehicle includes determining a 3D graphic sample model. A shape of the sample model has concave portions having curvatures determined through 3D modeling and gradients of an inner surface of each concave portion. A molded sample having the same general shape as the sample model is injection molded. Information related to scratch occurrence positions is acquired from the molded sample. Information of curvatures and gradients of the concave portions of the sample model are acquired and collected at positions on the sample model corresponding to the scratch occurrence positions. A limit angle and limit angle are determined by using the collected information and preset curvatures for the concave portion of a design of the interior part. The interior part having the concave portion with a shape based on the determined draft angle and the preset curvatures can then be injection molded.

Abstract: The present invention provides a process for fluid assisted injection molding comprising the step of providing an injection molding apparatus having a mold body that defines a mold cavity. The process further comprises the steps of supplying a quantity of fluent plastic to the mold cavity, following by injecting a fluid into the mold cavity. A reservoir is selectively connectable to a plastic injection runner, and can be opened to the runner to receive molten plastic ejected by the introduction of the fluid to the mold cavity. When the reservoir is thusly connected, the pressure of the fluid forces the plastic through a supply passage, in a direction substantially opposite to its initial injection direction.

Abstract: A method and system for multiple-cavity gas-assisted plastic injection molding. Each of the mold cavities are oriented in the vertical direction with the valve gates for the plastic material being positioned at the lower vertical ends of the mold cavities. With four mold cavities, an “X”-shaped runner pattern is utilized, although an “H”-shaped pattern could also be utilized. The centerline of the manifold is offset from the centerline of the mold. Gas is injected through in-article gas pins positioned in the mold cavities. The direction of the melt front advance is vertical from the bottom of the mold cavities to the top of the cavities. The gas pin location is also at the gate end of the part, either at or forward of the gate or resin entry point.
