Note: Heating steel for insertion into polypropylene

Objective:

Heating magnetic steel to 300 °F (149 °C) for insertion into a polypropylene board

End Product:

Pallets

Equipment:

Ambrell EKOHEAT 40 kW, 50-150 kHz induction heating system with a workhead and coil specifically designed for this application

Materials:

Hollow steel beam with two rails 3 in (76.2 mm) apart with steel barbs 0.25 in (6.35 mm) long and 0.04 in (1.02 mm) thick
polypropylene sandwich-ribbed reinforced board .50” (12.7 mm) thick

Temperature:

300 °F (149 °C)

Frequency:

108 kHz

Testing:

A single turn channel coil was used to heat the steel beam. The rail reached 300 °F (149 °C) in 20 seconds. The polypropylene board was pushed down on the steel beam to join the metal-to-plastic bond.

Benefits:

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

  • Faster production time

  • Even distribution of heating

  • “Greener” manufacturing of pallets using reusable, recyclable materials
