9月12日,我院金属材料教研室和大冶钢厂联合研制的高韧性易切削塑料模具钢(5NiSCa)通过国家鉴定。专家们认为:新钢种填补了我国复合系易切削塑料模具钢的空白,在国际上属独创,达到世界先进水平。 这种新钢种,已在全国三十多家厂矿企业的生产中试用,用于注塑模、胶木模、橡胶模、印刷线路板凹板及精密冷冲模等。生产试用表明,新钢种可锻性好,热处理简单,预硬后制模直接使用,提高了模具精度和光洁度,从而提高了塑料制品的表面质量,保证了制品精度,缩短了制模周期,减少了修模次数,提高了模具寿命,降低了成本,能代替进口模具。
On September 12, our high-toughness and easy-cutting plastic mold steel (5NiSCa), jointly developed by our institute’s metal materials department and Daye Steel, passed the national appraisal. Experts believe that: the new steel to fill the gap of China’s composite system free-cutting plastic mold steel, is internationally original, reaching the world advanced level. This new type of steel, has been in the country more than thirty factories and mines in the production trial, for injection mold, bakelite mold, rubber mold, printed circuit board concave and precision die and so on. Production trial shows that the new steel is malleable, heat treatment is simple, pre-hardened mold directly used to improve the mold accuracy and finish, thereby enhancing the surface quality of plastic products to ensure product accuracy and shorten the molding cycle, Reduce the number of mold repairs, improve die life, reduce costs, can replace imported molds.
