Iyo bigeze kubibumbano, abantu bakunze guhuza ibishushanyo bipfainshinge, ariko mubyukuri itandukaniro riri hagati yabo riracyari ingirakamaro cyane. Nkuko gupfira guta ari inzira yo kuzuza umwobo wubatswe nicyuma cyamazi cyangwa igice cyamazi cyamazi ku kigero cyo hejuru cyane kandi ukagikomeraho igitutu kugirango ubone gupfa. Mubisanzwe bikoreshwa mubyuma, mugihe kubumba inshinge ari kubumba inshinge, uburyo nyamukuru bwo kubumba thermoplastique, thermoplastique ikozwe mumashanyarazi, ishobora gushyuha inshuro nyinshi kugirango yoroshe kandi ikonje kugirango ikomere, inzira yumubiri, ihindurwe, bivuze ko ishobora kuba ikoreshwa nka plastiki ikoreshwa neza.
Itandukaniro riri hagati yimpapuro zipfa nububiko bwa plastiki.
1.
2.Irembo ryibipapuro bipfa gutandukana nubwa inshinge zitera inshinge, bisaba umuvuduko mwinshi wo gukora cone ya diverion kugirango isenye ibintu.
3.Ibishishwa byo gupfundika ntibikeneye kuzimya intanga zipfa, kubera ko ubushyuhe buri imbere mu cyuho kibumba burenga dogere 700 iyo bipfuye, bityo buri mubumbe uhwanye no kuzimya rimwe, umwobo wububiko uzarushaho gukomera no gukomera, mugihe ibishushanyo rusange byinshinge bigomba kuzimya HRC52 cyangwa byinshi.
4.Gupfa gushushanya mubisanzwe muri cavit yo kuvura nitriding, kugirango wirinde akavuyo gakomeye.
5.Mu rupfu rusanzwe rushobora kwangirika, hejuru yinyuma ni ubuvuzi bwubururu.
6. Ugereranije nudukingirizo two gutera inshinge, ibipapuro bipfa gupfa bifite ibisobanuro binini kubice byimukanwa (nka slide core), kubera ko ubushyuhe bwinshi bwibikorwa byo gupfa bizatera kwaguka kwinshi. Niba gukuraho ari bito cyane bizatera ifata gufata.
7. Igice cyo gupfa gishobora gutandukana hamwe nibisabwa hejuru, kubera ko amavuta avanze aribyiza cyane kuruta plastiki, ubushyuhe bwinshi hamwe nibintu byumuvuduko mwinshi uturuka hejuru yo gutandukana bizaguruka cyane.
8. Inshinge zo gutera inshinge muri rusange zishingiye kumapine ya ejector, gutandukanya ibice, nibindi birashobora kunanirwa, ibipapuro bipfa gupfa bigomba gufungura ibinure byuzuye no gukusanya imifuka ya slag (gukusanya umutwe wibikoresho bikonje).
9. Kubumbabumbwa bidahuye, gupfa-guta umuvuduko wo gutera inshinge, igice cyumuvuduko watewe. Ububiko bwa plastiki busanzwe buterwa mubice byinshi, bifata igitutu.
10. Ibipapuro bipfa gupfundika kubisahani bibiri bimaze gufungurwa, ibumba rya plastiki imiterere yibicuruzwa bitandukanye ntabwo ari bimwe.
Byongeye kandi, ibishushanyo bya pulasitike hamwe n’ibipfa bipfa gukora mu gukora ibyuma biratandukanye; ibishushanyo bya pulasitike bikoreshwa muri rusange S136 718 NAK80, T8, T10 nibindi byuma, mugihe ibishishwa bipfa gukoreshwa cyane cyane 3Cr2, SKD61, H13 nkibyuma birwanya ubushyuhe.
