              MIM工藝的關鍵

              time:2024-01-05Views:160 Author:Best Seiko

              (1)專業喂料:大約90%的金屬粉末與10%的粘結劑混合成均質的喂料。相比于傳統粉末冶金,金屬粉末(微米級)的粒徑和極低的雜質含量確保了MIM燒結密度到達理論密度的98%;而特殊配制的粘結劑能提供注射時的良好活動性也能保證高效的脫脂才能。


              (2)精細注射成形:應用注射機將MIM喂料加熱并平均填充到模具型腔,冷卻后得到MIM注射坯。契合MIM特性的模具與合理的工藝匹配是此工序的關鍵。


              (3)脫脂:采用專業脫脂爐逐漸高效去除注射坯中的主體粘結劑,殘留的骨架粘結劑維持產品外形以便脫脂件移入燒階段。


              (4)燒結成形:在MIM的真空爐或氛圍爐中,脫除骨架粘結劑,并在接近熔點的溫度下使金屬粉末致密化成完好的金屬體,經冷卻得到近乎廢品外形的燒結件。


              (5)后制程工序:對外觀件在產品停止相應的外表處置或機加工處置,如噴砂。拋光、清洗、PVD鍍膜、攻絲、CNC等工序。
