Carbide drawing (concave, convex) mold with high hardness, good finish, wear resistance, impact resistance and other characteristics of the normal working conditions, can stretch up to 200 million pieces of stainless steel is about; stretch ordinary iron device about 250 million, compared with the Cr12 mold material, the service life is 5-10 times more than its price is only 2-3 times its high wear resistance, brightness is good, effective in reducing the product pull flower, greatly reducing the number of times for the mold, and indirectly enhance the production rate
