The Injection Molding Machine (IMM) is designed to Melt Polymer and Distribute the Melted Polymer into a Mold with the objective to Produce Perfect Plastic Parts. In order to mold perfect plastic parts a knowledge and skill in a number of disciplines is required such as; Material, Part Design, Tool/Mold Design and Processing.
The Plastics Industry has been using pressure-force and position sensing feedback from the IMM for controlling the mold filling phase of the injection process without a direct readout of the melt state, melt temperature and viscosity of the polymer.
An analysis of a unique Temp-Tek TM Inductive Electromagnetic Melt Temperature Sensor in the Injection Molding process is presented. Placement within the barrel/nozzle yields important data relative to melt state, melt temperature, viscosity and equipment condition, revealing the ability of the Plasticating Screw and Screw Tip to prepare a quality Melt Pool with the correct Viscosity for distribution. Placement within the mold cavity(s) reveals filling and shrinkage dynamics. Advanced math models help in determining good/bad part manufacturing. The Temp-Tek TM Sensor’s output will be recognized as the most important variable to monitor and control when attempting to make quality injection molded parts and the machine variables will become a means for duplicating the Melt Rheology generated by the System. The Temp-TekTM System bridges the Gap between the Injection Molding Machine and the Polymer.
