MOLD HALF WITH METAL-MATRIX COMPOSITE AT FEATURE AREAS, AND ITS METHOD OF PRODUCTION |
摘要 |
A mold half, especially for blow molding of thermoplastic articles, has a mold body defined at least in part by a single piece of aluminum or aluminum alloy mold material having a cavity and a pinch-off or other feature area and further having a metal-matrix composite (MMC) layer formed integrally in the mold body at the pinch-off or other feature area. A mold is fabricated from two mated mold halves. A process of producing a mold half involves machining a single piece of mold material to provide a mold body having a cavity and a pinch-off or other feature area, the pinch-off or other feature area being of smaller dimension than required for the mold half, integrally forming a metal-matrix composite layer in the pinch-off or other feature area to build up the pinch-off or other feature area to at least a dimension required for the mold half. The metal-matrix composite comprises an aluminum-nickel alloy matrix (e.g. AI-12Si alloy alloyed with Ni) having WC particles embedded therein or a aluminum matrix (e.g. AI-12Si alloy) having TiC particles embedded therein and has greater wear resistance, greater strength, greater toughness or any combination thereof than the mold material. |
