Flame Treating has supplied induction heat treating services since 1956.  Traditionally a skilled operator set up the job.  He ran the first piece based on his visual interpretation of the temperature.  Inspection followed.  If it met the print, run the parts.

 Then things began to change.  More stainless, air hardening and high speed steel opportunities started to show up.  Quality requirements became more complex.  New opportunities for processing auto components grew significantly.  Automation was necessitated.  Induction tempering cycles became critical and longer.  And of course the PLC became the standard for controlling the process.

 To meet these challenges FTECO adopted the use of optical pyrometry, automated indexing, lift and rotating tooling, location sensing of parts, correct part sensing.  All of course made possible by use of PLC’s to control the process.  And then a program presented to us to induction harden about 165,000 shafts a month for an auto application lead us to combining scanning with the above improvements.

 Today we commonly use these techniques to insure the product quality and integrity.
