    I have not more info on the KPS band manufacture.
    The FES bands were made of mixture of "granulated" and "mechanical" (mechanicaly manufactured) iron powder. The powder mixture is pressed with 2,4-3,0 tons per square centimeter. The resulting ring is then cooked at 970-1050 degrees Celsia for about 2 hours. The bands cool down in the owen to prevent rust. Then they are impregnated with parafine by inserting them to liquid parafine (70-80°C) for 20 to 30 minutes. Then the bands are packaged and sent of to be pressed onto the body. The temperature must not exceed 50°C during pressing and other manufacture proceses.
    The bands are protected from rust by coating.
