An LWRT plus fabric injection overmolding process for the direct injection molding of thermoplastic features onto the B-side of a formed, finished Light Weight Reinforced Thermoplastic panel. The panel having an A-side finish cloth, non-woven, TPO, Vinyl or similar material placed into the injection molding press and injection molding tool, and then the features are injection molded onto the panel without damaging the A-side finish.

A molding condition setting device acquires data showing a state of an injection molding machine, calculates a feature showing the state of the injection molding machine on a basis of the acquired data, and calculates a feature fluctuation rate obtained by normalizing the feature on a basis of a reference value selected from among the features according to a prescribed condition. Meanwhile, the molding condition setting device acquires information relating to a change of the value of the operation command item and stores history of the change, and generates and stores history information in which the calculated feature fluctuation rate and the information relating to the change of the value of the operation command item are associated with each other.

A coinjection molded multi-layer container includes an inner layer, an outer layer, and a barrier layer. The inner layer includes a first polymeric material and forms an inside surface of the container. The outer layer includes the first polymeric material and forms an outside surface of the container. The barrier layer is located between the inner layer and the outer layer and includes a second polymeric material less permeable to gas than the first polymeric material. The barrier layer is biased toward the inside surface or the outside surface such that the inner layer and the outer layer have different thicknesses.
