    • Low cost water based binder system was developed for shaping ferrous, nonferrous metals and/or ceramics parts by injection molding processes. The process comprises the steps of preparing a mixture containing a gel-forming powder comprising carrageenan, metal and/or ceramic powders, de-ionized water and a gel-strengthening additive. The mixture is injection molded to produce self-supporting articles. The present invention provides a direct compounding and molding of metal and/or ceramic feedstock. Additionally, a coating composition comprising gelatine, water and a metal and/or ceramic powder is used to form coating layers on selected materials.
    • 开发了低成本的水基粘合剂系统,用于通过注射成型工艺成型有色金属,有色金属和/或陶瓷部件。 该方法包括制备含有包含角叉菜胶,金属和/或陶瓷粉末,去离子水和凝胶强化添加剂的凝胶形成粉末的混合物的步骤。 将混合物注射成型以产生自支撑制品。 本发明提供金属和/或陶瓷原料的直接配混和模塑。 此外,使用包含明胶,水和金属和/或陶瓷粉末的涂料组合物在所选择的材料上形成涂层。
