Size:                                Thickness 150-800mm, Width610-2000mm, Length2000-6000mm
Main uses:
            1.It is easy to process mould directly in hardness in advance condition.

            2. It can meet the Plastic module with opacities or the ordinary surface gloss. Such as ;TV,washer, the Large and medium-sized mold shell
            3. Thickness 700mm of mold is forged ,the heat treatment is not necessary to open the box, increasing the production capacity.
Main property:
             1.Vacuum degassing for steelmaking, It is lower contents for impurities and gas ,

             2. Compact structure, uniform hardness
             3. The size is stabilize, the precision is persistent for mould products
