Note: Heating a pin to cut holes (rubberized material)

Objective:

Heating a pin assembly to cut holes in a rubberized material

End Product:

Rubberized material

Equipment:

Ambrell 4.2 kW induction heating system, equipped with a remote workhead containing one 1.0 μF capacitor.
An induction heating coil designed and developed specifically for this application. 

Materials:

Metal disc 3.75 in OD (95.25 mm) with 72 pins .375 in (9.5 mm) long, .09735” (2.47 mm) OD 

Temperature:

518 °F (270 °C)

Frequency:

195 kHz

Testing:

A single-turn channel coil is used to heat the disc. Power is applied and the disc rotates at 14 rpm to maintain a constant temperature of 518 °F (270 °C). 

Customer is currently cutting holes in the rubberized material without heat and is having a problem with the pins sticking. By adding heat to the process the sticking is
eliminated.  

Benefits:

  • Precise and consistent application of heat

  • Consistent and repeatable results

  • Hands-free heating that involves no operator skill for manufacturing
