Note: Heating aluminium susceptor for powder expansion

Objective:

Expand powder into solid form for use in crash helmets

End Product:

Crash helmets

Equipment:

Ambrell 5 kW induction heating system, equipped with a remote workhead containing four 2.6μF capacitors for a total of 2.6μF
Two pancake coils 110 mm (4.3 in) dia. with 45 mm (1.8 in) gap, in a headphone configuration designed and developed specifically for this application.

Materials:

Microspheric powder
Aluminium chamber 110mm (4.3 in.) diameter x 35mm (1.3 in.) deep used to hold powder

Temperature:

150 °C (302 °F)

Frequency:

104.5 kHz

Testing:

The bottom of the susceptor chamber is sprayed with a release agent and microspheric powder is added to the chamber. The chamber is heated for 120 seconds to reach 150Âş C (302Âş F) changing the powder into solid form. It is then allowed to air cool to 70Âş C (158Âş F) and removed from the chamber. 

Benefits:

  • reduces cycle time for increased production

  • energy efficient - only heating the part allowing small production runs

  • is very flexible allowing a variety of molds to be used
