Annealing of Brass Musical Instruments

Application: Annealing 

Industry: Manufacturing & Automation 

Application Objectives: In high-performance manufacturing, production consistency is critical. A leading connectivity solutions provider turned to UltraFlex’s advanced induction annealing system to solve a key challenge—annealing targeted zones without affecting structural hardness elsewhere. 

Equipment: Power Supply SBT-3 with HSB-3 heat station 

Key Parameters 

  • Heating cycle – below 1 sec. 

Process 

The engineering team conducted five tests using the SBT-3 power supply and HSB-3 heat station. Each test focused on rapidly heating targeted zones without affecting the opposite side of the part. Heat cycles ranged from 0.5 to 0.8 seconds, with power levels between 2.7 and 3 kW. The optimal result was achieved at 0.8 seconds and 90% power, providing consistent and controlled annealing as required. 

Results and Conclusions 

The tests confirmed that the SBT-3 unit, paired with a custom single-turn coil, delivered precise and consistent annealing. The setup met the application’s requirements for rapid, controlled heating. To prevent unintended heat transfer to the opposite side of the part, a targeted water-cooling solution was also recommended. This optimized configuration now offers the manufacturer improved quality control and higher production reliability.
