Operational Progress : Steel-choosing→Blanking →Forging Steel →Rough Processing →Heat treatment →Finishing→Testing Knives are available with polished side faces ,High cost performance ,Punctual delivery . Slitter knives are manufactured to a thickness tolerance of ±0.002mm-0.003mm(±0.00007 inch-±0.00012inch). Parallelism tolerances is within 0.003mm (0.00012 inch) These are all prerequisites for the best possible slitting results. Materials : 9CrSi ,6CrW2Si , H13 ,Cr12MoV ,G1 , G2 ,G3 and etc . Electro slag remelting The largest ingot can reach 3 tons in Goodklife company .The ingot obtained by this remelting/refining process is very homogeneous and free of internal defects . The segregation of the ingot (called macro-segregations ) are substantially eliminated and the segregations of crystals (called macro-segregations ) are significantly reduced . The ESR remelted material improve following mechanical characteristics :   Improved toughness due to increased homogeneity and isotropy   Improved creep resistance properties   Best fatigue strength and tenacity properties as well as outstanding tensile strength   Improved purity  Forging steel The largest electro-hydraulic hammer is 4.5 ton .And more than 6 skilled technicians work for us .After forging ,the inside microstructure becomes much closer and the metal grain size becomes much smaller . It can evevate the characteristics and quality of the knife ensuring a longer life .  Rough processing No less than 40sets of processing equipment in the rough processing workshop of Goodklife company , including lathe ,milling machine , planer , drill machine etc. Skilled workers are employed in its rough processing workshop .
