Injection molded articles and methods of making injection molded articles. The methods include the use of a first plasticizing unit and a second plasticizing unit on a common frame feeding a first mold and a second mold on the common frame. Separating the production of each part of a two-part article into separate plasticizers and molds allows for the tuning of production parameters on a per-part basis, improving part flatness and part-to-part weight variance.

Method of producing injection molded articles

Methods of making polymer compositions containing volatile functional agents are provided, along with compositions and articles made from such methods. The methods include mixing one or more volatile functional agents into one or more polymers in a first extruder to form a masterbatch, further mixing the masterbatch in a second extruder having a volume that is larger than a volume of the first extruder, maintaining the mixing temperatures of both the first and second extruders below the volatilization temperature of the one or more volatile functional agents during the first and second mixing steps, and forming the mixture of the one or more volatile functional agents and the one or more polymers into pellets having a substantially uniform distribution of the one or more volatile functional agents in the one or more polymers.
