金属丝和金属纤维历来用机械的方法进行生产。目前市场上出售的金属丝或金属丝制品几手全部都是用轧制、拉拔、锤锻、挤压和机械加工的方法制得的。但是,应当看到,金属丝及其制品的直接铸造法已经出现——有的在试验研究阶段,有的已经投入生产。毫无疑问,铸造制品的组织和性能往往与机械法生产的制品迥然不同;这种差别往往有很大的优点。金属纤维的直接铸造不是一种新工艺。涉及这种工艺的专利至少可以追溯到1882年。 Wire and metal fibers have traditionally been produced mechanically. The few wires or wire products currently on the market are all made by rolling, drawing, hammering, extruding and machining. However, it should be noted that direct casting of wire and its products has occurred - some in the pilot phase and some already in production. There is no doubt that the organization and properties of foundry products are often quite different from those produced by mechanical methods; such differences often have great advantages. Direct casting of metal fibers is not a new process. The patents relating to this process date back to at least 1882.
