Metal Stamping Transformer Calculation

Anybody know how to calculate the complete transformer property (dimension, no. of turns, wire type selection) for a transformer rating at 240V,50Hz input and 25V,20A output.

Any books or website that 1 can refer u 2 which have a guideline for designing low frequency, high current metal stamping transformer?

You may try Ansoft Maxwell 3D, which is a excellent tool for transformer design. I do the similar simulation as you do.
