Abstract:
1. A method of providing a multi-layer molding system for molding a molded article, comprising the steps of: providing a modular molding system having an initial-build configuration for producing a molded article of a first molding composition, wherein the initial-build configuration includes i) a molding structure of a purpose-built mono-layer molding system; and ii) a first subset of a molding structure of a purpose-built multi-layer molding system; providing the modular molding system having the initial-build configuration includes the steps of providing: an injection unit having a base upon which is arranged an ‘A’ injection unit; a clamp unit; a stationary platen of the clamp unit having an ‘A’ passageway for accommodating a nozzle of the ‘A’ injection unit; the stationary platen having a ‘B’ passageway for accommodating a nozzle of a ‘B’ injection unit; a mount connected to the base, the mount connectable with a ‘B’ injection unit support; a main control module including a controller linked with a control device for the ‘A’ injection unit, a control device for the ‘B’ injection unit, and a control interface that is configured for linking the control device of the ‘B’ injection unit that are arranged in an auxiliary control module; a power manifold connected to the base, the power manifold being configured to be connectable with a ‘B’ injection unit; and a cover plate for the ‘B’ passageway; wherein the modular molding system is field upgradable with providing a module having a remainder subset of the molding structure of the purpose-built multi-layer molding system to an upgraded configuration for producing the molded article including a combination of the first molding composition and a second molding composition.
