Heat Treat Today conducted a survey with those companies that perform in-house heat treating as well as commercial heat treaters who use induction heating equipment. The results represent approximately 450 induction units, and we received very interesting and beneficial information from the questions posed. Below is a sampling of the questions and responses.
When asked the number of induction coils owned, 27% have over 100 coils, 16% own 50 to 100, and 13.5% have ownership of between 16 to 30 coils. Interestingly, 50% of respondents design and make the vast majority of their induction coils.
There were eight different power supply and transformer selections noted in the results. 62.5% use IGBT generators, while 33.3% use vacuum tube generators, and tied for third with 25% of respondents using thyristor or MOSFET generators.
Surveys. Polls. While well-designed ones can require time to complete authentically, the effort is worth the data received because it helps many make informed decisions. Heat Treat Today believes that people make better decisions when they are well-informed, and so, with that thought in mind, if you’re interested in seeing the full report of this induction survey, please email me at Karen@heattreattoday.com.
