一段關於射出成型原文文章的翻譯(10點)

Injection molding is similar to hot-chamber die casting.The pellets or granules are fed into the heated cylinder,and the melt is forcedunto the mold either by a hydraulic or by the rotating screw system of an extruder.

As in plastic extrusion, the barrel is heated externally to promot melting of the polymer.In injection-molding machines,however,a a far

greater portion of the heat transferred to the polymer is due to frictional heating.

    第二行 forcedunto 有沒有打錯?

    您是RD嗎?您打的英文部分有打錯的地方我改過了,不知對不對,你看一下。不過我想意思上不會有什麼影響。

    然而在注塑機台裡,傳遞到聚合物身上的熱量極大部分是來自於摩擦熱。

    是,改成這樣才是正確的。

    參考資料: 和射出成型現場合作過,也現場看過熱室壓鑄運作的實況
