Ninggalake pesenCasting mati sing digawe ing proses iki bisa beda-beda kanthi ukuran lan bobote saka sawetara ons nganti 100 kilogram. Salah sawijining aplikasi sing umum saka bagean cast tali yaiku jarum - kurungan tembok tembok tembok, asring mbutuhake iga lan bos ing njero interior. Sikil logam kanggo macem-macem peralatan lan peralatan asring mati. Sawetara komponen mobil uga diprodhuksi nggunakake casting mati, kalebu piston, sirah silinder, lan blok mesin. Bagéan diisi mati liyane kalebu propeller, gears, bushings, pompa, lan katup.
Mati casting minangka proses manufaktur sing bisa ngasilake bagean logam sing kompleks kanthi nggunakake cetakan sing bisa digunakake maneh, sing diarani mati. Proses casting die melu nggunakake tungku, logam, mesin casting mati, lan mati. Logam kasebut, biasane minangka aloi sing ora ferrous kayata aluminium utawa seng, dilebur ing tungku banjur disuntik menyang mati ing mesin tiwas mati. Ana rong jinis utama mesin mesin casting - mesin kamar panas (digunakake kanggo wesi kanthi suhu lebur sing kurang, kayata zinc) lan mesin rempah sing adhem (digunakake kanggo aloium). Bedane antara mesin kasebut bakal rinci babagan bagean ing peralatan lan alat. Nanging, ing loro mesin, sawise logam molten disuntik menyang mati, kanthi cepet adhem lan solidifes menyang bagean akhir, diarani casting. Langkah-langkah ing proses iki diterangake kanthi rinci ing bagean sabanjure.
Sebagian mati cast bisa beda-beda kanthi ukuran lan mulane mbutuhake langkah-langkah kasebut kanggo nutupi macem-macem. Akibaté, mesin casting die dirancang kanggo saben macem-macem nilai spektrum sing luwih gedhe. Conto spesifikasi kanggo sawetara ruangan panas lan kamar kadhemen mati mesin casting diwenehi ing ngisor iki.

Pilihan materi kanggo casting mati adhedhasar pirang-pirang faktor kalebu kapadhetan, titik lebur, kekuatan, resistensi karat, lan biaya. Bahan kasebut uga bisa mengaruhi desain bagean. Contone, panggunaan seng, yaiku logam mulus sing dhuwur, bisa ngidini tembok tembok tipis lan permukaan sing luwih apik tinimbang akeh wesi liyane. Bahan kasebut ora mung nemtokake sifat-sifat saka pemutus pungkasan, nanging uga mengaruhi mesin lan alat kasebut. Bahan kanthi suhu sing lebur, kayata wesi seng, bisa mati cast ing mesin ruangan panas. Nanging, bahan kanthi suhu lebur sing luwih dhuwur, kayata alloys aluminium lan tembaga, mbutuhake panggunaan mesin cold chamber. Suhu lebur uga mengaruhi alat kasebut, amarga suhu sing luwih dhuwur bakal duwe pengaruh gedhe ing urip mati.
