Development of Barrel Heating via Induction in Injection Molding Machine

Abstract:

A barrel heating system will be developed by using induction heating instead of current resistance heating. The experiment results showed the induction heating system can change successfully the current resistance heating system in heated the barrel of injection molding machine. A working coil coupled with magnetic concentrator bars was also considered. Finally, the uniformity of temperature distribution is compared between two barrel heating systems.
