Once these elements are operating properly, all that’s required for ongoing production is a steady supply of the right resin, usually provided through a resin-distribution system.

Yet, it can be easy for an operator, working with multiple resin “source” hoses and dozens of identical manifold “destination” slots, to connect the wrong hose to a given destination. The only question then is, how much is this error going to cost? Will it cost a hopper cleanout? Will it cost a material purge through the machine screw? Will it cost the need to sort out and destroy molded parts? Will it cost a downstream part safety concern or even prompt a recall of potentially contaminated or weakened parts?
