Mechini ea ho betsa libotlolo tsa letoto la FG ea PET e tlatsa likheo tšimong ea mochini oa ho betsa o lebelo le phahameng oa lapeng. Hona joale, lebelo la China la hlobo e le 'ngoe le ntse le le haufi le 1200BPH, ha lebelo la machaba la hlobo e le 'ngoe le fihla ho 1800BPH. Mechini ea ho betsa e lebelo le phahameng e itšetlehile ka thepa e tsoang kantle ho naha. Ka lebaka la boemo bona, Faygo Union Machinery e ntlafalitse mochini oa pele oa ho betsa o lebelo le phahameng oa Chaena: mochini oa ho betsa libotlolo oa letoto la FG, oo lebelo la oona la hlobo e le 'ngoe le ka fihlang ho 1800 ~ 2000BPH. Mochini oa ho betsa libotlolo oa letoto la FG o kenyelletsa mehlala e meraro hona joale: FG4 (4-cavity), FG6 (6-cavity), FG8 (8-cavity), 'me lebelo le phahameng le ka ba 13000BPH. E ntlafalitsoe ka boikemelo ka botlalo, e na le litokelo tsa rona tsa thepa ea kelello, 'me e fumane litokelo tsa molao tse fetang 8 tsa naha.

Mochini ona o na le sistimi ea ho kenya le ho jarolla ka boiketsetso libotlolong. E sebetsa bakeng sa mefuta eohle ea libotlolo tsa metsi a nooang, libotlolo tse nang le khabone le libotlolo tse tlatsang ka ho chesa. FG4 e entsoe ka limojule tse tharo: ho tloha ho lifti, ho etsa unscrambler le mochini oa moamoheli.

Mochini oa ho phunya libotlolo oa letoto la FG ke moloko o mocha ka ho feletseng oa mochini oa ho phunya o otlolohileng, o khetholloang ka lebelo la oona le phahameng, matla a tlase le tšebeliso e tlase ea moea o hatelletsoeng, o nang le moralo o motle oa sebopeho, sebaka se senyenyane, lerata le fokolang le botsitso bo phahameng, ha ka nako e ts'oanang o latela maemo a naha a bohloeki ba lino. Mochini ona o tšoantšetsa boemo bo holimo ka ho fetisisa ba mechini ea ho phunya e otlolohileng ea naha. Ke lisebelisoa tse loketseng tsa ho etsa libotlolo bakeng sa likhoebo tse mahareng le tse kholo.
