I. "Xinning" bar-shaped forging mould adopts chilling forming technology. The surface of the product is smooth, slick and the grains on which are evenly distributed. Its rigidity is significantly improved and the core and surface are basically of the same rigidity, thus, enhancing the abrasion-resistant performance of forging ball.
II. "Xinning" bar-shaped forging mould is easy to be operated and has high melted iron use efficiency, high technological yield, few forging defects and long service life.
III. "Xinning" bar-shaped forging mould can help manufacturers reduce cost, and is most applicable to middle and low chromium forging product with a diameter of over φ20mm.
