Abstract: The invention provides an article, a method and an apparatus of forming expanded plastic materials in a steam chest mold having out of die draw features. This is achieved by means of a cavity pull system. The cavity pull system allows for the provision of molded features outside the die draw and is designed to operate on a cam type system using two stainless steel rods running at a right angle to one another. A gear mechanism allows molded features, e.g. holes, to be formed at any angle on any part design where enough part geometry exists to accommodate the forming features and in the tool for mechanism components. The invention is advantageously employed in the formation of holes outside the die draw in vertically stacked injection tools for energy absorbers used in vehicle bumper fascias. The provision of out of die draw molded features is useful for fascia component locating or attachment.

Abstract: Methods for combining conductive filled low surface energy substrates, such as but not limited to polyolefins, and flame applied nitrogen based coupling agents are described. The methods include adding a conductive material to a surface and or matrix of the thermoplastic substrate so as to form a conductive thermoplastic substrate and a flame applied nitrogen-based coupling agent to form functional groups on the conductive thermoplastic substrate. The methods provide improved paint transfer efficiency, paint coverage, and adhesion durability characteristics. The methods are especially suitable for paintable automotive components, such as but not limited to exterior body panels, fascias, and the like.
