China OEM e entsoeng ka tšepe e sa hloekang castings e hlahisoang ke mokhoa oa ho lahla hlobo ea lehlabathe le machining a CNC.
Ho lahla lehlabathe ho sebelisa lehlabathe le letala (lehlabathe le mongobo) kapa lehlabathe le omeletseng ho etsa mekhoa ea ho bopa. Theho lahla lehlabathe le letalake mokhoa oa khale ka ho fetisisa o kileng oa sebelisoa historing. Ha ho etsoa hlobo, lipaterone tse entsoeng ka lehong kapa tšepe li lokela ho hlahisoa e le ho etsa sekoti se sekoti. Ka mor'a moo, tšepe e qhibilihisitsoeng e tšela ka mokoting ho etsa li-castings ka mor'a ho pholile le ho tiisa. Ho lahla lehlabathe ho theko e tlase ho feta lits'ebetso tse ling bakeng sa nts'etsopele ea hlobo le karolo ea ho lahlela yuniti. Ho lahla lehlabathe, kamehla ho bolela ho lahla lehlabathe le letala (haeba ho se na tlhaloso e khethehileng). Leha ho le joalo, matsatsing ana, mekhoa e meng ea ho lahla le eona e sebelisa lehlabathe ho etsa hlobo. Ba na le mabitso a bona, joalo kaho lahla hlobo, furan resin e koahetsoeng ka lehlabathe (ha ho mofuta oa ho baka),foam e lahlehilengle vacuum casting.
Re na le mefuta e fapaneng ea ho latsoa bakeng sa khetho ea hau. Karolo ea boikhethelo bakeng sa projeke ea hau e tla ba khetho ea mokhoa oa ho lahla o tla sebeletsa litlhoko tsa hau hantle. Sebopeho se tummeng ka ho fetisisa ke sa lehlabathe se kenyelletsang ho etsa setšoantšo sa sengoathoana se phethiloeng (kapa mohlala) se hatelitsoeng ka lehlabathe le li-add adtives ho etsa setšoantšo sa ho qetela. Mohlala o tlosoa ka mor'a hore hlobo kapa maikutlo a thehoe, 'me tšepe e hlahisoa ka mokhoa oa ho matha ho tlatsa sekoti. Lehlabathe le tšepe lia aroloa 'me samente ea hloekisoa le ho phethoa bakeng sa ho romelloa ho moreki.
Mamello ea ho lahla e arotsoe ka Dimensional Casting Tolerances (DCT) le Geometrical Casting Tolerances (GCT). Setsi sa rona se ka thabela ho bua le uena haeba u na le kopo e khethehileng mabapi le mamello e hlokahalang. Mona ho tse latelang ke boemo ba ho mamellana ka kakaretso boo re ka bo fihlelang ka ho lahla lehlabathe le letala, ho lahla hlobo ea likhetla le lehlabathe le sa bakeng la furan resin:
✔ DCT Kereiti ka Green Sand Casting: CTG10 ~ CTG13
✔ DCT Kereiti ka Shell Mold Casting kapa Furan Resin Sand Casting: CTG8 ~ CTG12
✔ Kereiti ea GCT ka Green Sand Casting: CTG6 ~ CTG8
✔ Kereiti ea GCT ka Shell Mold Casting kapa Furan Resin Sand Casting: CTG4 ~ CTG7
Melemo ea Mokhoa oa ho Lahlela Lehlabathe
1- Theko e tlase ka lebaka la thepa ea eona ea hlobo e theko e tlaase le e ka sebelisoang hape le lisebelisoa tse bonolo tsa tlhahiso.
2- Mefuta e mengata ea boima ba yuniti ho tloha ho 0.10 kg ho isa ho 500 kgs kapa ho feta ho feta.
3- Sebopeho se fapaneng ho tloha ho mofuta o bonolo ho isa ho o rarahaneng.
4- E loketse litlhoko tsa tlhahiso ea bongata bo fapaneng.
