Wetin na Blow Molding?
Blow molding na plastic forming process we dɛn kin yuz fɔ mek olo pat. I min se dɛn fɔ ɔt wan plastic tin te i dɔn rɔtin, dɔn i fos am fɔ go insay wan mold kaviti ɛn inflayt am wit kɔmprɛsd ɛya. Dis prɔses de mek di plastic big ɛn tek di shep fɔ di mol, we de mek wan pat we gɛt ol.
Tri men kayn blow moldin de:
Ekstrushɔn blo moldin (EBM) .
Injekshɔn blo moldin (IBM) .
Injekshɔn strɛch blow moldin (ISBM) .
Ɛni kayn gɛt in yon spɛshal kwaliti ɛn bɛnifit dɛn.

Injekshɔn Blɔ Moldin .
Injɛkshɔn Blɔ Molding (IBM) na wan manufakchurin prɔses we de kam togɛda wit injɛkshɔn moldin ɛn blo moldin tɛknik. Dɛn kin yuz am fɔ mek hol plastic pat dɛn wit prɛsis dimɛnshɔn ɛn kɔmpleks shep dɛn.
Di prɔses involv sɔm impɔtant tin dɛn:
Injɛkshɔn moldin fɔ di prɛfɔm : Dɛn injɛkt molten plastic insay wan prɛfɔm mol, we de mek wan olo, tiub-layk shep wit wan finish nɛk ɛn trɛd eria.
Transfer of di preform : Di prɛfɔm de transfa pan wan kɔr rod to di blow moldin steshɔn. Dis de du we di prɛfɔm stil hot.
Infleshɔn ɛn kol : Na di blo moldin steshɔn, dɛn put di prɛfɔm insay wan blo mol. Dɔn dɛn kin yuz kɔmprɛsd ɛya fɔ mek di prɛfɔm bɔku, ɛn dis kin mek i bɔku ɛn tek di shep we di mold kaviti gɛt. Di pat kin kol te i strɔng.
