Nyanzvi mugadziri wemichina ye thermoforming.
Thermoforming inzira yekugadzira iyo pepa repurasitiki rinopisa kuita a flexible shape, iyo inobva yaumbwa kana kuumbwa uchishandisa mold, uye ipapo yakachekwa kuita chikamu chekupedzisira kana chigadzirwa. Zvese zviri zviviri vacuum kugadzira uye kuumba pressure mhando dzakasiyana dze thermoforming process. The Musiyano mukuru pakati pekumanikidza kugadzira uye vacuum kugadzira ndiko nhamba yezviumbwa zvinoshandiswa.
Vacuum kugadzira ndiyo yakareruka mhando yeplastiki thermoforming uye anoshandisa mold uye vacuum kudzvanywa kuti uwane inodiwa chikamu geometry. Yakanakira zvikamu zvinongoda kunyatsoumbwa kune rimwe divi, senge contoured packaging yezvokudya kana zvemagetsi.
Ikoko imhando mbiri dzakakosha dzezviumbwa—chirume kana chakanaka (izvo zviri convex) uye munhukadzi kana kuti asina kunaka, ayo ari concave. Kune zviumbwa zvevarume, pepa repurasitiki inoiswa pachiumbwa kuti iite rondedzero yezvimiro zvemukati zve chikamu chepurasitiki. Kune zviumbwa zvevakadzi, mapepa e thermoplastic anoiswa mukati me mold kunyatsogadzira zviyero zvekunze zvechikamu.
Mukugadzira kumanikidza, a pepa repurasitiki rinopisa rinotsikirirwa pakati pezviumbwa zviviri (saka zita), pane kudhonzwa pachiumbwa chimwe chete nekukweva. Pressure kuumba kwakanakira kugadzira zvikamu zvepurasitiki kana zvidimbu zvinoda kuve yakanyatso kuumbwa pamativi ese uye/kana inoda kudhirowa kwakadzama (vanofanira kuwedzera kure/kudzika kuita mold), senge mudziyo macasings anoda kutarisa aesthetically kufadza kunze uye pinda panzvimbo kana kukwana saizi chaiyo padivi remukati.
