Production technique for metamerism roller

The invention relates to the making of metamerism roller. It pours fluid metal into centrifugal machine driven rotary mold to allow the stuffing of the mold and the solidification of materials. Through repetitive testing, it turns the forging bar into required product once for all, without blanking, drilling, hole expanding, with material texture fine, mechanical and physical features greatly improved, with strong force of the product and abrasion resistant feature, low in forging material cost, reduced in machining cost, improved in product benefit, reducing energy over thirty percent, with the strength and abrasion resistant feature and using efficiency improved over thirty percent with reduced cost.
