由于粉末冶金工藝在材料生產(chǎn)過程中并不熔化材料，也就不怕混入由坩堝和脫氧劑等帶來的雜質(zhì)，而燒結(jié)一般在真空和還原氣氛中進(jìn)行，不怕氧化，也不會給材料任何污染，故有可能制取高純度的材料。 </p> <p> 很多新興金屬材料的制作研發(fā)與粉末冶金密切相關(guān)。粉末冶金是以金屬粉末為原料，經(jīng)過成型和固結(jié)，鎮(zhèn)海精密粉末冶金，制造金屬材料，鎮(zhèn)海精密粉末冶金、復(fù)合材料及制品的工藝過程。高性能金屬粉末的開發(fā)與生產(chǎn)，鎮(zhèn)海精密粉末冶金，對提高粉末冶金材料和制品性能、推動粉末冶金技術(shù)進(jìn)步起著至關(guān)重要的作用。

粉末冶金汽車零部件行業(yè)總產(chǎn)值在汽車工業(yè)總產(chǎn)值中占半壁江山，2015年為3.8萬億元。零部件行業(yè)平均利潤率為6%~8%，外資合資企業(yè)超過15%，自主整體偏低。2015年，國內(nèi)零部件研發(fā)投入占比*為2%，自主創(chuàng)新和技術(shù)研發(fā)嚴(yán)重不足。目前，國內(nèi)零部件企業(yè)大約有10萬家，規(guī)模以上（主營業(yè)務(wù)收入2000萬元）企業(yè)大概1.3萬家。盡管國內(nèi)整體零部件產(chǎn)品關(guān)鍵重要技術(shù)水平在這幾年有很大進(jìn)步，但是在高技術(shù)壁壘和重要部件，尤其是電力電子控制體系，以及高可靠性基礎(chǔ)部件方面仍然是外資企業(yè)在主導(dǎo)的，自主零部件企業(yè)較薄弱，外資零部件企業(yè)在國內(nèi)*為制造基地，并未進(jìn)行產(chǎn)品技術(shù)導(dǎo)入。 </p> <p> 作為中國粉末冶金零件行業(yè)的本土品牌，在激烈的市場競爭中，東睦股份逐漸形成了獨(dú)特的品牌，其商業(yè)價值和社會價值也得以體現(xiàn)。年報顯示，2016年東睦股份營業(yè)收入14. 67億元，同比增長7.22%：營業(yè)利潤2. 02億元，同比上升6. 73%。 </p><div style="width:100%;text-align:

雙向壓制雙向壓制一般分為陰模浮動式壓制和陰模拉下式壓制。粉末治金陰模浮動式壓制陰模浮動式壓制工作原理：陰模由彈簧支承，處于浮動狀態(tài)，下模沖固定不動，上模沖在凸輪帶動下向下進(jìn)入陰模型腔，對粉末施加向下壓力。開始加壓時，由于粉末與陰模型腔壁間摩擦力小于彈簧支承力，只有上模沖向下移動，隨著壓力增大，粉末對陰模型腔壁間的摩擦力大干彈簧支承力時，陰模型腔與上模沖一起向下運(yùn)動，與下模沖間產(chǎn)生相對移動，從而達(dá)到雙向壓制的效果。陰模浮動式壓制的一個循環(huán)有以下步驟。A裝料：手工或者由自動送粉器把粉末均勻裝入陰模型腔。B上沖下壓：粉末填充完畢后，陰模彈簧支撐，下模沖位置固定不變，上模沖在壓機(jī)凸輪帶動下，向下進(jìn)入陰模型腔，對陰模型腔中的粉末施加向下壓力。C陰模浮動：隨著上模沖施加的壓力不斷增大，粉末對陰模型腔壁間的摩擦力也不斷增大，當(dāng)此摩擦力大干陰模型腔的彈簧支撐力時，陰模型腔與上模沖一起向下運(yùn)動，直到坯件成型。
