Together, these tools can help design and position the coil properly and apply appropriate settings to achieve the best results with induction heating. Induction heating provides an efficient alternative to the typical approaches to rapid heating and cooling of injection molds. While it comes with its own set of design challenges, simulation software can help ensure the system is designed properly and will perform optimally. ensure a high-quality surface finish on the part. Temperature plots also can help molders evaluate final part warpage, the time required to heat the mold surface and the cooling time required to reach a safe ejection temperature.

Go to moldmakingtechnology.com/zones for a complete list. Potential drawbacks of heating induced through magnetic fields that are generated by alternating current are not self- evident. Additional evaluation tools are available that specifi- cally isolate and identify any issues that may occur with the electromagnetic heating process itself. Magnetic field plots identify the strength of the heating effect throughout the mold to ensure it is concentrated on the mold surfaces that are actu- ally forming the part (see Figure 6). Joule heating studies can identify which areas of the mold are heated and ensure there is OMP400—Optical transmission strain gauge probe.More details at renishaw.com/omp400 • Lower contact forces for less stylus bend and pre-travel • Excellent 3D performance • CMM-level accuracy • Excels in the harshest machine conditions Learn more: Renishaw.com/RMP600 Renishaw's strain gauge technology offers an unrivaled opportunity to control the variables of process control for small to medium-size machining centers.
