The materials selection and Heat Treatment of Plastic Cup Mold
Abstract With the plastics industry is increasingly wide range of applications in everyday life,plastic mold steels are more and more demanded in plastic molds industry ,plastic mold material for the processing and use of mold performance and service life have a great impact in molds ,it is requirement higher on the quality and service life of molds. As a result of the actual plastic mold has a large variety plex use, how to die according to different working conditions, the scientific effort to find ways to improve die life, has e an important tool technology research. Practice shows that the plastic mold material with a reasonable selection of plastic mold heat treatment is to improve scientific and effective way of life. Introduced how to choice plastic mold steel and usual used mold steel and using situation in mold factory were stated in detail, the theoretical basis for working out the heat treatment processes of these steels and for selecting steel grades are also provided in this paper .Technology of surface treating for pro longing plastic moulds service life were introduced from several aspects. It is pointed out that techno logy of surface treating is an important way for prolonging plastic moulds service life when being used properly.
Key words: Plastic mold materials, Invalidation, Materials selection, Heat treatment, Surface treating
