JUST BEFORE CASTING, THEY HEAT
THE CYLINDER-BORE LINERS USING HIGH-FREQUENCY
ELECTRIC CURRENT. ALUMINUM WILL BOND BETTER
TO HOT METAL. THEY FILL THE MOLDS
FROM THE BOTTOM TO AVOID CONTAMINATING THE METAL
WITH ALUMINUM OXIDE. OXIDE FORMS WHEN MOLTEN ALUMINUM
COMES INTO CONTACT WITH THE AIR. POURING INTO THE TOP OF THE MOLD WOULD EXPOSE THE METAL
TO OXYGEN, AND THE POURING ACTION ITSELF
WOULD MIX IN THE OXIDE
