Ni ubuhe buryo bwihariye bwo gutekerezaho bwo gukoresha plungers zikoreshwa na mandrels murwego rwo hejuru rwo kwishyiriraho impeta?

Kubyakozwe cyane, kwishyiriraho intoki kugumana impeta ntigikora neza kandi bishobora guteza impungenge impeta. Kwiyubaka byikora ikoresha mandel yafashwe na pusher (plunger). Ikariso ya mandel ntigomba kurenza $ 10 $ dogere kugirango habeho inzibacyuho neza. Impera yimbere ya mandel igomba kuba ntoya kurenza diameter ya shaft, kandi impande zikurikira zigomba guhuza neza neza. Gusunika bigomba gukoresha imbaraga za axial kumuzenguruko wimpeta kugirango wirinde 'kuzunguruka' cyangwa kugoreka, bishobora kuganisha kumubiri uhoraho. Ku mpeta y'imbere, amaboko yafashwe akoreshwa mu guhagarika impeta. Ikintu gikomeye ni 'gusunika imbaraga,' bigomba gukurikiranwa; igicucu gikurikizwa cyerekana kudahuza bishobora gutobora igiti cyangwa inzu.
