Zeziphi iimpawu zokubumba umbhobho ongenanto?

Inkqubo yokubumba i-hollow blowing ineempawu zokubumba okulula, ukusebenza kakuhle kwemveliso, ixabiso eliphantsi lemveliso, kunye nokusebenza okulula.Izikhongozeli zokupakisha zinokuveliswa ngokubunjwa ngokuvuthela kwiibhotile zamehlo ezinomthamo weemililitha ezininzi zokugcina kunye nezikhongozeli zothutho ezinomthamo wamawaka eelitha aliqela.Iiplastiki ezisetyenziselwa ukubumba umbhobho ongenanto ziquka: i-polyethylene, i-polyvinyl chloride, i-polypropylene, i-polystyrene, i-polyester ye-thermoplastic, i-polyamide, i-cellulose acetate, njl., phakathi kwayo i-polyethylene isetyenziswa ngokubanzi.
