粉末微注射成型技术(μPIM)是一种新型的技术,采用传统的粉末注射成型的方法来制备整体尺寸为毫米级,局部结构的尺寸达到微米级,精度达到微米级的制品,有着极其光明的前景。由于钛合金难以加工的特性,采用μPIM制备微型的钛合金零件能实现低成本、大批量的生产,目前在医疗器械领域、高端音响制备以及微型传感器制备领域已经用到μPIM技术来制备微型钛合金零件。
Powder microinjection molding technology (μPIM) is a new type of technology that uses conventional powder injection molding methods to make products with millimeter-scale overall dimensions, micrometer-scale local structures, and micrometer-scale accuracies, with extremely bright prospect. Due to the difficult processing characteristics of titanium alloys, the use of μPIM to prepare miniature titanium alloy parts can achieve low-cost and high-volume production. At present, μPIM technology has been used in the field of medical devices, high-end audio production and micro-sensor manufacturing to prepare miniature titanium alloys Components.
