脉动压制是成形粉末制品和烧结件处理的新方法之一。这个方法是一种创举,它通过应用脉动力极方便地取代复杂的机械装置。振动是一个组成部份。脉动压制工艺比传统工艺效率更高。粉末压制分四个阶段(图1)。在d阶段,自由沉落的粉末准确地填入料腔。较小的粒 Pulsating press is one of the new methods for the processing of powdered products and sintered parts. This approach is a pioneering move that easily replaces complex mechanical devices by applying pulsating force. Vibration is an integral part. Pulsating press process is more efficient than traditional process. Powder compaction in four stages (Figure 1). In stage d, the free-falling powder fills the pocket accurately. Smaller grains
