Abstract
Systems () and methods for making different plastic products () in a single melting process are provided. A method includes melting a plastic resin in a first extruder () to form a melt () and transferring at least a portion of the melt to a second extruder (). Any portion of the melt () that is not transferred to the second extruder () is formed into a first plastic product (). Additives () are blended with the melt in the second extruder to form a second melt (), and a second plastic product () is formed from the second melt ().
