Question

In dielectric core baker, several metallic plates are used for supporting the cores in the system.

(a) True

(b) False

I have been asked this question by my school principal while I was bunking the class.

The above asked question is from Dielectric Core Bakers topic in division Core and Core Making of Casting-Forming-Welding I

Answer 1

Right choice is (b) False

Explanation: Dielectric core bakers are basically based on dielectric heating. The core supporting metallic plates cannot be used in this type of baker because they interrupt the potential distribution in the electrostatic field. To avoid this interruption or interference, cement bonded asbestos plates can be used for supporting the cores instead of metallic plates.
