I've done a little bit of research on this myself. It seems that Ap uses a method called investment casting, which is quite fascinating. In essence, it involves creating a wax model of the casing, then encasing it in a ceramic shell before melting away the wax and pouring in the molten stainless steel. It's a specific procedure that guarantees a high level of depth and grade.
