Art\u0131lar\u0131 ve Eksileri<\/h2>\n\n\n\nOrtak avantajlar<\/h2>\n\n\n\n\n- \u00d6n i\u015flem, s\u0131cakl\u0131k ve son i\u015flem so\u011fuk d\u00f6vmenin ucuz maliyetine katk\u0131da bulunur. Di\u011fer metal \u015fekillendirme y\u00f6ntemleri, i\u015f par\u00e7as\u0131n\u0131n \u0131s\u0131t\u0131lmas\u0131 gibi bir t\u00fcr \u00f6n i\u015flem gerektirir.<\/li>\n\n\n\n

- Metalle \u00e7al\u0131\u015fmak bir dizi soruna yol a\u00e7abilir.

Dezavantajlar<\/h2>\n\n\n\n\n- So\u011fuk d\u00f6vme kusursuz de\u011fildir.

- So\u011fuk d\u00f6vme yap\u0131labilecek metal t\u00fcrlerinde bir k\u0131s\u0131tlama vard\u0131r. Esnekliklerini kaybedecekleri ve \u00e7ekme gerilimi alt\u0131nda k\u0131r\u0131lacaklar\u0131 i\u00e7in sertle\u015ftirmek i\u00e7in zay\u0131f plastikli\u011fe ve gerilmeye duyarl\u0131 olanlar\u0131 se\u00e7memelisiniz. Sadece Rockwell \u00f6l\u00e7e\u011finde HRC 44 sertli\u011fine sahip metaller kullan\u0131labilir.<\/li>\n\n\n\n
