Zvigadzirwa zvepurasitiki zvinogadzirwa nemusanganiswa wesynthetic resin uye zvakasiyana-siyana zvekuwedzera semidziyo yakabikwa, uchishandisa jekiseni, extrusion, kudzvanya, kudira uye dzimwe nzira. Ipo zvigadzirwa zvepurasitiki zviri kuumbwa, ivo vanowanawo yekupedzisira kuita, saka kuumbwa kwepurasitiki ndiyo nzira yakakosha yekugadzira.
1. Injection molding inonziwo jekiseni molding. Inzira yekushandisa jekiseni muchina kukurumidza kubaya purasitiki yakanyungudutswa muforoma nekuisimbisa kuti iwane zvigadzirwa zvepurasitiki zvakasiyana.
2. Iyo extrusion molding method inzira inoshandisa screw rotation uye kumanikidzika kuti irambe ichibudisa plastiki yepurasitiki muhutu, uye kana ichipfuura nepakati peimwe chimiro chefa, purogiramu yepurasitiki yakakodzera chimiro chefa inowanikwa.
3. Compression molding, inozivikanwawo se compression molding, compression molding, compression molding, etc., ndeyekuwedzera mapellets akasimba kana zvidimbu zvakagara zvakagadzirirwa muforogo, uye kushandisa kupisa nekumanikidza kunyorovesa uye kunyunguduka, uye pasi pekumanikidzwa Nzira yekuzadza. iyo mold cavity kuwana zvikamu zvepurasitiki mushure mekurapa.
4. Blow molding (yechipiri chekugadzirisa mapurasitiki) inzira yekugadzira iyo mapurasitiki asina maburi anoputika uye akaremara nenzira yemhepo yakamanikidzwa, uye zvikamu zvepurasitiki zvinowanikwa mushure mekutonhora uye kuumbwa.
5. Kukandwa kwepurasitiki kwakafanana nekukandwa kwesimbi. Ndiko kuti, iyo polymer zvinhu kana monomer zvinhu mumhepo inoyerera inobayiwa mune chaiyo mold, uye pasi pemamwe mamiriro, inobatwa, yakasimbiswa, uye inoumbwa kuita nzira yekugadzirisa yezvikamu zvepurasitiki zvinoenderana negomba rekuumbwa.
6.Gas-assisted injection molding (inonzi gas-assisted molding) inzira itsva mumunda wekugadzirwa kwepurasitiki. Yakakamurwa kuita hollow forming, short shot, uye full shot.
