Ukucutshungulwa kwe-extrusion yensimbi kuyindlela ebalulekile yokucubungula ingcindezi ngokususelwa kumgomo wensimbi eyenziwe ngeplastiki.I-Metal extruder iyithuluzi elibaluleke kakhulu lokukhishwa kwensimbi.

I-Extrusion ingenye yezindlela eziyinhloko zokukhiqiza izinsimbi ezingafakwanga insimbi nezinto zensimbi nezensimbi nokwakhiwa kwezingxenye. Futhi kuyindlela ebalulekile yokulungiswa nokucutshungulwa kwezinto ezahlukahlukene ezithuthukile njengezinto ezihlanganiswayo nezinto zokwenziwa kwempuphu.

Kusuka ekushiseni okushisayo kwe-ingot yensimbi enkulu, ukukhishwa okushisayo kwamaphrofayli amakhulu we-tubular bar, ukukhishwa okubandayo kwezingxenye ezincane zokunemba, ukuqiniswa okuqondile nokubunjwa kwezinto ezihlanganisiwe nge-powder nezinto zezinhlayiya njengezinto zokusetshenziswa, ukwenza izinto ezinzima zokucubungula njengamakhemikhali e-intermetallic nezinto zokwenziwa kwe-superconducting, ubuchwepheshe besimanje be-extrusion busetshenziswe kabanzi.

Izindlela zokucubungula i-extrusion ikakhulukazi i-extrusion enhle, i-reverse extrusion, i-lateral extrusion, ingilazi i-lubrication extrusion, i-extrusion ye-hydrostatic, i-extrusion eqhubekayo.Ukucutshungulwa kwe-extrusion kubonakala ngokuxineka okuqinile okunezindlela ezintathu, okulungele ukuthuthukisa amandla we-plastic deformation wensimbi, ukuthuthukisa ikhwalithi yomkhiqizo, ukwenza ngcono ukwakheka kwangaphakathi nokusebenza komkhiqizo.

Ngaphezu kwalokho, ukucutshungulwa kwe-extrusion nakho kunezicelo ezahlukahlukene, ukuguquguquka kokukhiqiza, inqubo elula kanye nokutshalwa kwemali okuncane.

Ama-alloys angenayo i-alloys anephuzu eliphansi lokuncibilika, njenge-aluminium ne-aluminium alloys, yizinto ezisetshenziswa kakhulu ukucubungula kwe-extrusion.
