Isilayidi somngundo weplastiki ngokubanzi sinokwenziwa ngentsimbi ye-45 #, ecinywayo kwaye inomsindo ukunyusa ukuxhathisa ukunxiba.Isikhundla sesithuba sesikhokelo esithambekele singaba ngaphambili okanye ngasemva, esinokumiselwa ngokuguquguqukayo ngokobukhulu besikhunta.Nangona kunjalo, i-angle kunye nobude bekholamu yesikhokelo se-oblique kufuneka inqunywe ngokomgama ohambayo we-slider;ngokubanzi, i-angle yekholamu yesikhokelo se-oblique yi-20 ° okanye i-25 °.Ukumisela i-angle esisigxina kunokuncedisa ukuveliswa kwentsimbi ye-oblique pad, ukwenzela ukuba ugweme isidingo sexesha ngalinye.Ukwenza iimpondo ezithambekileyo zee-engile ezahlukeneyo.Sebenzisa umthetho we-cosine wemisebenzi ye-trigonometric ukubala ubude besithuba sesikhokelo se-oblique.

Kukho iintlobo ezininzi zonyango lwe-surface ye-mold, eziqhelekileyo ziyi-surface egudileyo kunye ne-pockmarked surface, ezo ziyimiphumo engaphezulu ekufuneka yenziwe ngokokhetho lomthengi.
Naliphi na inqanaba lokugqitywa komphezulu kwifektri yethu lingasetyenziswa.

Isiseko sokubumba esiqhelekileyo sithetha ukuba isiseko sokubumba senziwe ngezinto zeP20, kwaye isikhunta senziwe ngeteknoloji yesakhelo sesibuko.Ngokuqhelekileyo isetyenziselwa ukungunda kwamanye amazwe.Inzuzo yolu setyenziso kukuba ukuba kukho ingxaki kwi-mold, inokulungiswa ngokulula ngokutshintsha iindawo, ezingcono.
