Lisebelisoa tsa Mold ea Shell

Ho hlahisa likhetla ho sebelisa ho lahla lehlabathe la resin e koahetsoeng esale pele ho etsa liforomo. E amohela ho chesoa ha khetla e chesang (mokhoa oa ho baka) 'me e koahetsoe ke mokokotlo pele litšepe tse qhibilihisitsoeng li tšela ka har'a hlobo e lokiselitsoeng. Ntho e ka sehloohong ea ho bōptjoa ke lehlabathe la phenolic resin le koahetsoeng esale pele, le theko e boima ho feta lehlabathe le letala le lehlabathe la resin la furan. Ho feta moo, lehlabathe lena le ke ke la sebelisoa hape. Ka hona, likhetla tsa ho bopa li na le litšenyehelo tse phahameng ho feta ho lahla lehlabathe. Leha ho le joalo, ha ho bapisoa le ho lahla lehlabathe le letala, likhetla tsa ho bopa li na le melemo e mengata e kang mamello e phahameng ea dimensional, boleng bo botle ba holim'a metsi le liphoso tse fokolang tsa ho lahla. Mokhoa oa ho lahla likhetla o loketse ka ho khetheha bakeng sa ho hlahisa libopeho tse thata, likepe tsa khatello, boima ba 'mele le li-castings tse hlokang ho qeta holimo holimo.
