Everything You Need To Know To Find The Best Graphite Heating Rod

There are few options.  Induction heating below 1kW is not useful, so I don't know of any real products.  There is a wand type device for automotive purposes

Your only other choice is to build it yourself, or buy one of those silly toy circuits.  Same thing, really, as a proper induction heater circuit needs frequency tracking, control and feedback, and protection circuits, and those take time.  Anything you'd throw together would be just a toy.  (So, hey, if you have the parts on hand, you might as well make something basic, instead of waiting for delivery.)

The other problem is frequency.  A few mm graphite rod probably won't heat very quickly for frequencies under 100kHz.  Most toys aren't intended to run that fast.  So you'll probably be building it yourself, but also having trouble dealing with stray inductance, burning transistors, etc... 

For power control, you'd probably just vary the supply voltage/current into one of these things, yeah.

Off the shelf?There are few options. Induction heating below 1kW is not useful, so I don't know of any real products. There is a wand type device for automotive purposes http://www.theinductor.com/ but it's above 1kW, and I think near or above $, too.Your only other choice is to build it yourself, or buy one of those silly toy circuits.

High density graphite is ideal for vacuum heating elements. The graphite elements are highly inert and the material actually increases in strength as it becomes hotter. Another feature of the material is that it has a low expansion coefficient and is resistant to degrading due to constant heat cycling therefore, it has a good lifespan in this respect and a relatively fast ramp rate.

The elements are made from blocks of high purity graphite and with the correct material selection the graphite can be machined into detailed forms for one off or low volume batches. If you can not find your requirement in the stock items below or in the gallery then please contact us to discuss you requirement further. The designs can be of a 3D nature to produce a tubular heater or flat as required. Alternatively, we can design elements or work from existing drawings.

Thermic Edge can provide Silicon Carbide coated elements or Titanium Carbide coating to further enhance these element in terms of purity and using graphite in air.
