Isici Somkhiqizo
Ukulahleka kwe-foam elahlekile (eyaziwa nangokuthi i-real mold casting) yenziwe nge-foam plastic (i-EPS, i-stmma noma i-epmma) i-polymer izinto ezibunjiweyo nosayizi ofanayo njengoba izingxenye ezizokhiqizwa futhi zihlanganiswe, futhi zihlanganisiwe Nge-Refractory Coating (eqinisiwe), ebushelelezi futhi ephefumula) futhi yomisiwe, ingcwatshwa esihlabathini esomile se-quartz futhi yabekwa ngaphansi kokuvota okuphefumulayo okunezinhlaka ezintathu. I-molten Metal ithululelwa ebhokisini lesihlabathi lokubumba ngaphansi kwengcindezi engemihle, ukuze imodeli yezinto ezibonakalayo ifudunyezwa futhi ihlungwa, bese ikhishwe. Indlela entsha yokuphonsa esebenzisa insimbi ewuketshezi ukuze isule inqubo yesikhathi sokuphonsa isikhathi esisodwa esakhiwe ngemuva kokupholisa nokuqina ukuze ikhiqize izinqubo. Ukuphosa okulahlekile kwe-foam kunezici ezilandelayo: 1. Izinkontileka zingekhwalithi enhle nezindleko eziphansi; 2. Izinto zokwakha azilinganiselwe futhi zilungele bonke osayizi; 3. Ukunemba okuphezulu, indawo ebushelelezi, ukuhlanzwa okuncane, kanye nemishini emincane; I-4. Izinkinga zangaphakathi zincishiswa kakhulu futhi ukwakheka kokuphonsa kwenziwa ngcono. Mnene; I-5. Ingabona ukukhiqizwa okukhulu nokukhiqizwa kwesisindo; 6. Ilungele ukukhiqizwa kokukhiqizwa kwabantu abaningi kakhulu; 7. Ilungele ukusebenza kwezandla kanye nokukhiqizwa komugqa okuzenzakalelayo komhlangano nokulawulwa kokusebenza; 8. Isimo sokukhiqizwa somugqa wokukhiqiza sihlangabezana nezidingo zamapharamitha okuvikela ezemvelo. ; 9. Ingayithuthukisa kakhulu imvelo yokusebenza kanye nemibandela yokukhiqiza yomugqa wokukhiqiza, ukunciphisa amandla abasebenzi, futhi unciphise ukusetshenziswa kwamandla.
Ukuchazwa Komkhiqizo
Ukulahlekelwa kwe-Foam elahlekile (kusukela ngonyaka we-2018) ukuhlanganisa futhi kuhlanganise amamodeli epulasitiki e-foam afana ngosayizi nokwakheka ku-castings kuma-model cluster. Ngemuva kokuxubha ngenhlanganisela yokuphikisa nokusoma, bangcwatshwa esihlabathini esomile se-quartz futhi bavikelekile. Ngaphansi kwemibandela ethile indlela yokuthela insimbi ewuketshezi, okwenza imodeli ibe yi-Vaporize futhi idle isikhundla semodeli, bese iqinisa futhi iphole futhi ipholile ukwenza ukusakazwa okufiselekayo. Izici ezibalulekile zenqubo yendlela elahlekile ye-foam casting indlela ukukhiqizwa kwezikhunta zepulasitiki ze-foam kanye nokusetshenziswa kwengubo yokuphikisa; ukudlidliza nokuqina kwesihlabathi ngemuva kokuthi isikhunta sepulasitiki se-foam sifakwe ebhokisini lesihlabathi; kanye nokugcinwa kwe-vacuum ebhokisini lesihlabathi ngesikhathi sokuthulula. .
Ukuphonswa kwe-Foam elahlekile kudunyiswa imboni etholwayo njenge "kubuchwepheshe obusha bokuphonsa ngekhulu lama-21" kanye "nephrojekthi eluhlaza ekusakazeni". Ukulahleka kwe-Foam elahlekile kuqala kuhlolwe ngempumelelo yi-HF Shroyer ngo-1956. USolwazi A. WITMOSER wabambisana ne-Hartman ukukala ukukala. Kusukela ngo-1960s kuya kuma-1970s, kwakhiwa indlela kazibuzi le-Magnetic Magring. Kusukela ngo-1980s, inqubo yokuqala ebonakala ngengcindezi engemihle ye-vacuum kanye nokubumba kwesihlabathi owomile. Isizukulwane sesithathu sasilahlekelwa amagwebu.
I-Lost Foam Casting uhlelo lokusebenza oluphelele lokuqondisa izigwegwe oluhlanganisa amapulasitiki, amakhemikhali, imishini kanye nokuphonsa. Ihlanganisa ukulahlekelwa igwebu elahlekile nezinye izinqubo ezintsha zokuphonsa ukudala izindlela ezintsha zenqubo eziyinhlanganisela ukuthuthukisa ikhwalithi ye-Foam elahlekile. kanye nokusebenza kahle kokukhiqizwa kuthuthukisiwe.
