A hot runner process controller configured to monitor the status and operation of a hot runner system to autonomously generate information to improve the quality of injection molding process of a hot runner system having an inlet nozzle, one or more manifolds and one or more nozzles with actuator or without actuator, and one or more heating elements, the hot runner process controller is self-operating, and independent from the injection molding machine, includes: one or more sensors located on, in or at the hot runner system to detect the status and/or the operation of the hot runner system, and a processing unit and a memory. The processing unit is connected to the one or more sensors, wherein the memory stores data and program codes. The processing unit is configured to load and execute the program code to compare sensor information with the stored data and to determine if the hot runner system is in an operable status, and in case the hot runner system is in an operable status, configured to generate status information to activate the one or more heating elements and/or the one or more actuators enabling a production operation of the injection molding machine. In case the hot runner system is not in an operable status, configured to generate status information to deactivate the one or more heating elements and/or close or deactivate the one or more actuators disabling a production operation of the injection molding machine.

Physical foaming a footwear component with a single-phase solution of a polymeric composition and a supercritical fluid is provided. The method include temperature conditioning a mold and then engaging the mold with a robot that conveys the mold to a press. At the press a gas counter pressure is applied to a cavity of the mold before injecting a single-phase solution of a polymeric composition and a supercritical fluid into the cavity of the mold. The process continues with releasing the gas counter pressure from the cavity of the mold and then removing the footwear component from the cavity of the mold. The parameters of the method are configured for the formation of the footwear component in an automated manner.

A method of forming a urinary catheter is disclosed that includes injecting a polymer melt through a primary melt channel and into an elongated recess around an outer surface of a core; and controlling a first pressure of the polymer melt in a first secondary melt channel separately and individually from a second pressure of the polymer melt in a second secondary melt channel and reducing stress of the polymer melt along the elongated recess. Opening the mould and removing the core provides a moulded intermittent urinary catheter having an open distal end and a closed proximal tip.
