在粉末压制过程中,为减少摩擦,需加润滑剂。通常的作法是,在粉末中混入润滑剂。但是这样做,一方面降低了密度,另外还有污染环境等问题。有些润滑剂在烧结中不易除去,引起部件起皮,有些则沉积于炉壁上,降低炉子寿命。模壁外润滑可减少这些问题,但难于将润滑剂有效地保持在模壁上。美国锌公司经过多 In the powder pressing process, in order to reduce friction, need to add lubricant. It is common practice to mix lubricants in the powder. But doing so, on the one hand, reduces the density, in addition to environmental pollution and other issues. Some lubricants in the sintering is not easy to remove, causing parts from the skin, while others are deposited on the furnace wall, reducing furnace life. Mold wall lubrication can reduce these problems, but difficult to effectively maintain the lubricant in the mold wall. American zinc company after more
