Maphakathi no-1940s, kwakukhona imishini embalwa engenisiwe evulekile yamanje, kubandakanya: Umshini weCzech Polak 600 (Czech Force 76 (Chenging Force 76 t) kanye neChongQing) kanye neClongQing) ne-Consontal CHAMBER DISTING CASTING Machine ( I-USA .
Ngawo-1950s, izwe lami lenzelwe futhi lenza i-hydraulic 50- uhlobo uhlobo oluvundlile lwe-Chear-carsen chersic of 500 kn futhi 1 .} Ukucaciswa, amandla aphezulu wokuqubuka kwawo kwakungu 2 200 kn, amagumbi avundlile amnyama afa ama-casping emishini ye-Soviet Union, aguqule ukukhiqiza imishini emincane yama-soviet, okungukuthi imodeli engu-900 (amandla okubopha Uchungechunge lwemishini yokuphonsa eyakhiwe yangaphambilini eyenzelwe kanye nokukhiqizwa kwecala uJ 1125, J 1140 no-J1163 Full Hydraulic Cold Chamber Chamber Chamber Chamber Chamber Chamber Chamber Chamber Chamber Chamber Mashic; yakhelwe futhi yakha i-hydraulic evundlile evundlile Chamber Canber Chamber DEAD CHAMBER DID Machine enamandla ahlanganayo we- 4 000 kn (i-shanghai ekhombisa ithuluzi lomshini lokusebenza Ngawo-1980s futhi ekuqaleni kweminyaka yama-1990s, amayunithi afanele aqhubeka nokuqedela ukuthuthukiswa kochungechunge lwemishini ebandayo ebandayo ebandayo yokufa - amabutho ama-clamping cherce ngaphansi kwe-16,000 kn; Imishini e-vertical ebandayo yokufa okufayo yokufa nokufa nayo yakha imikhiqizo yochungechunge lweClamp Force Force olungezansi 2 500 kn; Ngo-1986, iyunithi yokuqala yasekhaya e-j1163 iyunithi ethengisa ngokuzenzakalelayo yakhiqizwa icala; Uphiko lokuqala oluguqukayo lwasekhaya oluguqukayo lwakhiwa ngo-1990, ngamandla okuqhuma kwe- 4 000 kn; Ngokuya ngomsebenzi wokuklama umshini wokufa, ngo-1980s, ukusebenza komjovo owenziwe ngomshini wokudla okufa wawuseduze kwalezi zikhathi zakwamanye amazwe ngaleso sikhathi; Eminyakeni elandelayo, idivaysi ezayo kanye nedivaysi yokuthola ipharamitha yaqondaniswa futhi yaphothulwa futhi umkhiqizo wasungulwa . Ngaleso sikhathi, i-Hot Chamber Mechanical Design Machine futhi yabeka uchungechunge lwemikhiqizo enomdlandla ongaphansi I-1,500 kn, futhi umshini ogcwele wokudambisa okugcwele mpo ubuye waba nochungechunge lwemikhiqizo enamandla okuqhuma kwe- 3 150 kn .
Ukuze uqhubekele phambili ukukhuthaza ukukhiqizwa komshini wokuphonsa kwengcindezi ephezulu, okujwayelekile kwepharamitha yokufa kwaqalwa ku-1990, kanti ukunemba komshini wokufa okufayo kwakhiwa futhi kwamukelwa ukunemba komshini wezobuchwepheshe Isisekelo .
