摘要： Methods and apparatuses for lubricating and filling a die cavity in a powder operation, wherein a plug member is inserted into a die cavity, a lubricant composition is fed into a peripheral zone of the die cavity to form a lubricant layer on die wall surfaces of the die cavity; a powder mixture is fed into a closed central zone of the die cavity; and the plug member is then removed from the die cavity to release the powder mixture such that the powder mixture outspreads and contacts the lubricant layer. The steps of feeding of the lubricant composition and powder mixture may be performed fully or at least partly simultaneously to reduce or minimize a cycle time. The method and apparatuses may be configured to further compact the powder to form a green compact; and eject the green compact. The powder mixture may include metallurgical powder or ceramic powder.
摘要翻译：用于在粉末操作中润滑和填充模腔的方法和装置，其中将塞构件插入模腔中，将润滑剂组合物进料到模腔的周边区域中，以在模腔壁的表面上形成润滑剂层模腔; 将粉末混合物进料到模腔的封闭中心区域; 然后将塞子构件从模腔中取出以释放粉末混合物，使得粉末混合物膨胀并接触润滑剂层。润滑剂组合物和粉末混合物的进料步骤可以完全地或至少部分地同时进行以减少或最小化循环时间。该方法和装置可以被配置为进一步压实粉末以形成生坯; 并弹出绿色契约。粉末混合物可以包括冶金粉末或陶瓷粉末。

摘要： Lubricant composition and related methods and apparatus for manufacturing a green compact in a die cavity during a powder metallurgy operation wherein the lubricant composition includes a first component and a second component. The first component has a starting phase, an active phase, and a transition temperature at which at least part of the first component changes state from the starting phase to the active phase. Upon contact with wall surfaces of the die cavity, the first component transitions from the starting phase to the active phase, and the second component adheres to the active phase of the first component to form a lubrication layer coating the die wall surfaces. The component may be a first solid particulate component, such as polymeric particulate material or a sugar, or a first gaseous component, such as water vapor or palm oil vapor, respectively able to melt or condense upon contact with die cavity.
