We use a variety of ceramic injection molding materials such as 99.8% alumina oxide, 96% alumina oxide, Zirconia Oxide and Silicon Nitride. Ortech refinement of alumina to 99.8% purity provides for more dense, harder, more abrasion resistant parts than those made by other processes, which speeds up the manufacturing process, and substantially reduces manufacturing cost! The resulting ceramic injection molding parts are superior in quality, and lower in cost.
Injection molding of Alumina Oxide(Al2O3) has superb material characteristics such as high electrical insulation, high mechanical strength, high wear and chemical resistance.
Injection molding of Zirconia Oxide (ZrO2) has the highest strength and toughness at room temperature of all the advanced ceramic materials. The fine grain size allows for extremely smooth surfaces and sharp edges. Applications include scissors, knifes, slitters, pump shafts, metal-forming tools, fixtures, tweezers, wire drawing rings, bearing sleeves and valves
Injection molding of Silicon nitride (Si3N4) features an excellent combination of material properties such as low density and chemical resistance. The microstructure causes high fracture toughness and makes silicon nitride resistant to mechanical impact. In addition, its low thermal expansion coefficient causes a very good thermal shock resistance.
