壓鑄與電鍍一般發生的問題有以下幾點: The issues that frequently occur described as follow:
水紋 : 大都集中位置為鑄件腔內脫氣或壓鑄溫度不足造成 Water Mark: Cause of the deoxidization of the mold cavity or the temperature was not proper. 針孔 集中位置為壓鑄局部過熱現象。 Pin Hole: Centering on the hottest part of the cast. 鑄孔 為壓鑄吸進冷料,以目前前端加料會有未完全融解 之料吸入, 射出成型、冷熱料相接之處易於形成鑄孔。 Casting Hole: Since it absorbed the cold liquid. The point that the cold and the hot liquid mixed together will become the casting hole. 縮孔 由於補充溫降所造成的收縮,以致最後冷卻的鑄件位置極易形成表面低陷的縮孔,類似冒口的縮孔。 Shrinkage: Cause of the low temperature from a supplement so that the surface of the cast that being cooled will be shrunk. Just like the shrinkage of the raiser. 凸點 澆道設計不良,射料時混入空氣,在未冷固前開模空氣遇熱膨漲,接近表面的氣泡會頂起鑄件表面而形成凸點。 Raised Speck: The design of the gate was not good enough. The gas entered into it while injecting the liquid, and the mould was opened while the cast was not firm so that the gas will expend when met the heat. Therefore the bubble will push the surface of the cast from the inside then it becomes a raised speck. 變形 未完全固化前或脫模不良,造成鑄件變形 Deformed: The mould has been taken off while the cast was still soft.
碰傷 鑄件掉落碰傷 Bumped: The cast was hurt cause of a fall. 刮傷 手工粗糙鑄件受他物刮傷表面 Scrap: The cast scraped by the other things. 裂紋 鑄件未適度冷卻前,脫模不良導致裂 Crack: Before the cast had not been cooled moderately, the mould had been taken off already. 模痕 模具表面傷痕附印在鑄件上 Mould mark: The mark of the mould prints a mark on the cast. 骯髒 鑄件沾到油泥、粉塵或污染物 Dirty: The cast was contacted with the waste oil, dust and waste things. 凹點 凹痕 壓鑄(壓力不足) (過熱) Dent: The pressure is not proper and too hot. 毛邊 模具表面合模不良,融料溢出。 Burr: Mould closing is not good enough.
