Tecast铸造尼龙有多种等级,具有良好的机械性能、优异的轴承和磨损特性以及铸造工艺的大尺寸能力。它的抗疲劳性、噪音阻尼能力、耐腐蚀性和重量轻,使Tecast成为轴承、齿轮、滑轮和链轮等金属更换应用的理想选择。与铁、铝、黄铜和青铜等金属相比,Tecast的重量只有青铜的八分之一,更易于操作和维护,在工业磨损应用中,它通常会取代这些金属。由于其优越的性能,Tecast通常替代的其他材料是层压酚醛塑料、弹性体和木材。Tecast具有优异的耐磨性,延长了部件寿命,降低了维护成本。它的配方很容易在杆、板和管中获得。非标准形状,如环、盘和块,可以小批量经济生产,交货期短。定制零件可以用相对便宜的工具铸造成尺寸或接近净形状。其独特的强度、耐磨性、韧性、可加工性和耐腐蚀性组合使Tecast铸造尼龙成为轴承、止推垫圈、衬套、耐磨垫、带轮、滚子、齿轮、链轮和车轮的理想选择。Tecast通常用于建筑设备、材料处理系统、游乐场游乐设施、纸浆和纸张处理设备、钢厂和工业设备。一种石墨粉末填充铸造6型尼龙,性能类似于6PAM,但更适合于潮湿环境。 TECAST™ cast nylon, available in a variety of grades, offers a combination of good mechanical properties, excellent bearing and wear characteristics, and the large-size capabilities of the casting process. Its fatigue resistance, noise damping ability, corrosion resistance, and light weight make TECAST™ ideal for metal replacement applications, such as bearings, gears, sheaves, and sprockets. At one-eighth the weight of bronze, TECAST™ is easier to handle and maintain than metals such as iron, aluminum, brass, and bronze, which it typically replaces in industrial wear applications. Other materials that TECAST™ commonly replaces because of its superior performance are laminated phenolics, elastomers, and wood. TECAST™ has excellent wear and abrasion resistance, resulting in extended component life and lower maintenance cost. Its formulations are readily available in rod, plate, and tube. Nonstandard shapes, such as rings, discs, and blocks can be economically produced in small quantities with short lead times. Custom parts can be cast-to-size or near-net-shape with relatively inexpensive tooling. Its unique combination of strength, wear resistance, toughness, machinability, and corrosion resistance make TECAST™ cast nylon ideal for bearings, thrust washers, bushings, wear pads, sheaves, rollers, gears, sprockets, and wheels. TECAST™ is commonly used in construction equipment, material handling systems, amusement park rides, pulp and paper processing equipment, steel mills and industrial equipment. A graphite powder-filled cast type 6 nylon with properties similar to 6PAM but better suited to wet applications. TECAST™ T Natural A cast type 6 nylon used in applications requiring cast nylon advantages without fillers. TECAST™ T BLACK A black cast type 6 nylon that is more UV resistant than natural. TECAST™ T BLUE A blue cast type 6 nylon with properties similar to TECAST T. Heat stable but with improved heat resistance properties. TECAST™ T MO A molybdenum disulfide- filled cast type 6 nylon used for general bearings and wear applications because of its superior strength and hardness. TECAST™ 6PAG A graphite powder-filled cast type 6 nylon with properties similar to TECAST T MO but better suited to wet applications. TECAST™ 6XAU A high heat (up to 260°F continuous), weather resistant cast type 6 nylon with superior fatigue-resistance and bearing properties. TECAST™ L An oil-filled cast type 6 nylon used in applications requiring excellent bearing and wear properties where external lubrication is difficult or impractical. |
