Recently, ultrasonic molding (USM) has emerged as a promising replication technique for low and medium volume production of miniature and micro-scale parts. In a relatively short time cycle, ultrasonic molding can process a wide variety of polymeric materials without any noticeable thermal degradation into cost-effective molded parts. This research work reviews recent breakthroughs of the ultrasonic injection molding and ultrasonic compression molding process regarding the equipment and tooling development, materials processing and potential applications in the medical industry. The discussion is centered on the challenges of industrializing this technology, pointing out the need for improvement of the current process's robustness and repeatability. Among the most important research areas that were identified are the processing of novel engineered and nanomaterials, the understanding and control of the ultrasonic plasticization process and the tooling and equipment development.
最近，超声成型（USM）已成为一种有前景的复制技术，用于中小规模生产微型和微尺度零件。在相对较短的时间周期内，超声成型可以加工各种聚合物材料，而不会出现明显的热降解，从而生产出具有成本效益的成型零件。本研究工作回顾了超声注射成型和超声压缩成型工艺在设备和模具开发、材料加工以及在医疗行业的潜在应用方面的最新突破。讨论集中在该技术产业化面临的挑战上，指出需要提高当前工艺的稳健性和可重复性。已确定的最重要研究领域包括新型工程材料和纳米材料的加工、超声塑化过程的理解和控制以及模具和设备开发。
