Shrink firimuchinhu chinowanzo shandiswa chekurongedza icho chinofarirwa nekusiyana-siyana, kusimba uye kudhura-kushanda.Inowanzoshandiswa mumaindasitiri akasiyana siyana anosanganisira chikafu nechinwiwa, mishonga, zvemagetsi uye zvinhu zvevatengi.Shrink vagadziri vemafirimu vanoita basa rakakosha mukugadzira iyi yekurongedza zvinhu kuti isangane nezvinodiwa zvezvigadzirwa zvakasiyana.
Thekuderedza kugadzirwa kwemafirimumaitiro anosanganisira akawanda matanho anoda hunyanzvi uye nemazvo.Nhanho yekutanga mukugadzirisa kusarudzwa kwezvinhu zvakasvibiswa.Shrink firimuinowanzogadzirwa kubva ku polyethylene, thermoplastic polymer inogona kuumbwa zviri nyore nekupisa.Hunhu hwezvinhu zvakabikwa hwakakosha sezvo huchikanganisa zvakananga kuita kwechigadzirwa chekupedzisira.
Kana zvigadzirwa zvasarudzwa, zvinonyungudutswa uye zvakasanganiswa kuti zvigadzire polima yakanyungudutswa.Iyi polima inobva yadyiswa muextruder, muchina unoumba zvinhu zvacho kuita sefirimu.Iyo polima yakanyungudutswa inopfuura nepakati pekufa, ichigadzira firimu rakatsetseka.Ukobvu hwemufirimu hunogona kugadziriswa nekugadzirisa gap rekufa.
Mushure mokunge firimu yakaumbwa, inopinda maitiro ekutonhora kusimbisa uye kudzikamisa chimiro chayo.Izvi zvinowanzoitwa nekupfuudza firimu kuburikidza nerunyoro rwechilled rolls.Firimu rakatonhodzwa rinobva rakungurutswa mumapumburu makuru akagadzirira kuenderera mberi nekugadzirisa.
Nhanho inotevera inosanganisira kushandisa michina yakakosha kupa iyo firimu shrink zvivakwa.Iyo firimu inopfuura nepakati inopisa uye mhepo inopisa inoputirwa pafirimu.Kupisa kunoita kuti firimu ideredze uye ienderane zvakasimba kune chigadzirwa, ichigadzira purogiramu yakachengeteka uye inodzivirira.
Kamwe iyofirimu rinodererakune chimiro chaidiwa, chinoongororwa nokuda kwehutano.Vagadziri vanotarisa mabubbles, kuderera kusingaenderane, kana chero hurema hunogona kukanganisa kushanda kwefirimu.
Kurongedza uye kunyora iwo matanho ekupedzisira mukugadzira maitiro.Shrink firimu inochekwa uye yakavharwa zvichienderana nehumwe hukuru uye zvinodiwa.Inobva yaiswa mumidziyo yakakodzera, yakagadzirira kugoverwa kumaindasitiri nemabhizinesi akasiyana siyana.
Muchidimbu,shrink vagadziri vemafirimukuita basa rakakosha mukugadzira zvinhu zvekurongedza zvemhando yepamusoro zvinosangana nezvinodiwa zvakasiyana zvemaindasitiri akasiyana.Maitiro ekugadzira anosanganisira matanho chaiwo kubva pakusarudza zvigadzirwa kusvika pakuongorora chigadzirwa chekupedzisira.Nekushandisa hunyanzvi uye michina yepamusoro,shrink vagadziri vemafirimuchengetedza kugadzirwa kweakavimbika uye akasimba ekurongedza mhinduro kune dzakasiyana siyana dzezvigadzirwa.
