Sprue ingori chiteshi chinotungamira epurasitiki yakanyungudutswa kubva pamuromo wejekiseni rekugadzira muchina kusvika panopindwa nejekiseni rose mold tool.. Icho chikamu chakasiyana kubva kune mold tool pachayo. Mumhanyi (runner) igadziriro yematanho anosangana nesprue, kazhinji mukati kana sechikamu chemudziyo wekuumbwa, iyo inotungamira purasitiki yakanyungudutswa muchikamu chemakomba mukati memudziyo wekuumbwa.

Kune mapoka makuru maviri evamhanyi (kupisa uye kutonhora) zvaunogona kuverenga nezvazvo pano. Pakupedzisira, gedhi ndiyo chikamu chegwara mushure memumhanyi anotungamira akananga muchikamu chegomba. Mushure mekuita jekiseni mold kutenderera (kazhinji masekonzi chete kureba) iyo yese yepurasitiki yakanyungudutswa inotonhorera ichisiya purasitiki yakasimba musprue, vamhanyi, magedhi, part cavities pachavo, pamwe chete nediki diki rekufashukira zvingangoita pamicheto yezvikamu (kana chisimbiso chisipo 100% rudyi).

Thermoset zvinhu, senge epoxy resin inorapa yakambofumurwa kumhepo, chinhu chinorapa uye chinopisa mushure mekurapa kana imwe chete kuedza kuchinyungudutsa. Thermoplastic zvinhu nekusiyanisa, chinhu chepurasitiki chinogona kunyungudutswa, tonhorera uye simbisa, zvozonyungudutswazve pasina kupiswa. Ne thermoplastic zvinhu izvo zvinhu zvinogona kushandiswa zvakare kushandiswa zvakare. Dzimwe nguva izvi zvinoitika pauriri hwefekitari. Vanokuya sprues / vanomhanya uye chero zvikamu zvinoramba.

Vanobva vawedzera izvo zvinhu kudzoka mune mbishi zvinhu zvinopinda mujekiseni rekuumba muchina. Nyaya iyi inodaidzwa kuti “kugayazve”. Kazhinji, madhipatimendi ekudzora mhando anozodzikamisa huwandu hweregrind inotenderwa kudzoserwa mupepanhau. (Zvimwe zvekushanda zvepurasitiki zvinogona kushatisa sezvo ichiumbwa nguva nenguva). Kana kuti, kana vane zvakawanda, fekitari inogona kutengesa iyi kugaya zvakare kune imwe fekitori inogona kuishandisa. Kazhinji regrind zvinhu zvinoshandiswa kune yakaderera-mhando zvikamu izvo zvisingade yakakwirira kuita zvivakwa.

  • Jekiseni Molding inodzokororwa zvakanyanya. Ndizvozvo, chikamu chechipiri chaunogadzira chinenge chakafanana nechokutanga nezvimwe. Ichi hunhu hunoshamisa kana uchiedza kuburitsa brand kuenderana uye chikamu chekuvimbika mukugadzirwa kwehuwandu hwepamusoro.
