Microwave and radio-frequency (electromagnetic wave energy) heating utilize magnetron systems with on/off time-proportioning control or amplitude modulation. Meet safety standards and FCC regulations.
In amplitude modulation, current power is adjusted to control instantaneous magnetron output. Remote sensors measure material temperature within microwave chamber or RF electrode arrangement and modulate magnetron power output to maintain temperature control.
For materials with minimal direct microwave and RF heating response, "susceptor" additives convert EMW energy to heat within the body of the material. RF energy and special susceptor additives can be used to yield advantages over microwave.

DALTON ELECTRIC HEATING CO., INC.
Watt-Flex split-sheath cartridge heaters with continuous coil reportedly give uniform temperature profile, often eliminating need for distributed wattage. Because unit has no coil segments and cold spots of conventional heaters, it is suitable for package and bag sealing bars. Hot-tip feature, accomplished by passing the coil across the tip of the heater, improves performance of sheet extrusion die or hotrunner gate probe by putting more responsive heat in the lip of the die or tip of the probe. Independent, bilateral expansion of the two legs effects contact of both sides of the sheath to a bore, providing better heat transfer and consequently a cooler-running coil. As heater is de-energized, it contracts, making heater removal easier and eliminating bore seizure. Grooved heaters externally accommodate needle-type thermocouples, which monitor process temperature, not internal coil temperature. Design allows independent replacement of thermocouple or heater.

Noren Thermal Pin heat conductors (similar to heat pipes) transfer heat quickly and uniformly from one part of a mold to another. Commonly used to extract heat for mold cooling, but also to transfer heat into hard-to-reach mold areas in thermoset molding. Units cool cores and molds faster than water to reduce cycle time and draw heat from the plastic, transferring it to water channels or to the mold base. Uniform heat transfer eliminates hot spots pulling. Only one water line is required. Thermal Pins eliminate scale and plugging of small-diameter water channels going into the core, reducing maintenance, and can isolate old or damaged mold components from the coolant when seepage or leak problems occur. In blow molding, the hollow unit uniformly cools the end of the blow pin and evenly cools necks of blow molded bottles. More than 350 sizes stocked. (See data sheet p. 245.)
