鍛造(Forging),是金屬壓力加工方法之一。指利用壓力改變金屬原料形狀,以獲得具有一定機械性能、一定形狀和尺寸的鍛件的一種加工工學。 鍛造是一種利用局部壓縮力對金屬進行成型的製造加工。
機械式鍛造,高速精密溫、熱模鍛機一使用精密模具開發及複動化鍛造製程技術,可以一次鍛造成型達到淨成型鍛造,使銅鍛件成形後,僅需少量加工或不再加工,並具有精確的外形、高的尺寸精度、形位精度和好的表面粗糙度的高優質鍛件。達到高效率、縮短開發時程及省料省成本之目標。
鍛造通常根據其進行的溫度進行分類:冷鍛造(一種冷加工)或熱鍛造(一種熱加工)。對於後兩者,金屬被加熱,通常是在鍛造中。鍛造零件的重量可以從不到一公斤到數百公噸不等。鍛造已經由鐵匠完成了幾千年;傳統產品有廚具、五金、手工工具、邊緣武器、銅鼓和珠寶。自工業革命以來,鍛造部件被廣泛用於需要高強度的機械;這類鍛件通常需要進一步加工來實現成品。如今,鍛造是一個重要的世界性產業。也是鍛造其中之一
根據加工時工件的温度,可將鍛造分為:熱鍛(再結晶(recrystallization)溫度以上);溫鍛(再結晶溫度~再結晶溫度的30%[註 1]);冷鍛(再結晶溫度的30%以下,一般是室温)。常把坯料加熱後,用手錘、鍛錘或壓力機等錘擊或加壓,使它發生塑性變形,成為一定形狀和尺寸的工件,所得的工件稱為鍛件,鍛造能改變金屬組織、提高其機械性能,因此在機械製造中常用來製造承受較大動載荷的零件。
鍛造成型達到淨成型鍛造,使銅鍛件成形後,僅需少量加工或不再加工,並具有精確的外形、高的尺寸精度、形位精度和好的表面粗糙度的高優質鍛件。達到高效率、縮短開發時程及省料省成本之目標。

Type of gate in a Shinto shrine Rōmon at Hannya-ji, a National Treasure. Note the absence of stairs to the second story. The rōmon (楼門, lit. tower gate) is one of two types of two-storied gates used in Japan (the other one being the nijūmon, see photo in the gallery below).[1] Even though it was originally developed by Buddhist architecture, it is now used at both Buddhist temples and Shinto shrines. Its otherwise normal upper story is inaccessible and therefore offers no usable s…
