Alumina（Al2O3）96%-99%
Zirconia (ZrO2)
Alumina of 96 % to 99.9 % is processed with different properties of material, designs of structure and colours. Injection molding of Alumina Oxide(Al2O3) has superb material characteristics such as high electrical insulation, high mechanical strength, high wear and chemical resistance.
Zirconia has a high edge strength and is thermally insulating. 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
The CIM material provides additional durability and strength in your products.
