Uburyo bwo gushushanya rotational, buzwi kandi nka rotational molding, rotational molding, rotary molding, nibindi, ni uburyo bwo gushushanya thermoplastic hollow hollow. Ubu buryo ni ukubanza kongeramo ibikoresho fatizo bya pulasitiki muri foromo, hanyuma igikoresho gikomeza kuzunguruka ku migozi ibiri ihagaze hanyuma kigashyuha, hanyuma ibikoresho fatizo bya pulasitiki biri muri foromo bigapfukwa buhoro buhoro kandi bikanashonga neza bigafatana n'umwobo w'ibumba bitewe n'imbaraga z'uburemere n'ubushyuhe. Ku buso bwose, bukorwa mu ishusho wifuza, hanyuma bugakonjeshwa kugira ngo bukore umusaruro.

(1) Bikwiriye gushushanya ibice binini n'ibinini cyane. Kubera ko uburyo bwo gushushanya buzenguruka busaba imbaraga z'urubaho kugira ngo bushyigikire uburemere bw'ibikoresho, ibumba, n'urubaho ubwarwo, ndetse n'imbaraga zo gufunga kugira ngo hirindwe ko ibikoresho bivamo amazi, nubwo byaba bitunganywa ibice binini n'ibinini cyane bya pulasitiki, nta mpamvu yo gukoresha ibikoresho biremereye cyane n'ibumba. Kubwibyo, mu buryo bw'imitekerereze, nta ruhare ntarengwa ku bunini bw'ibicuruzwa bikorwa n'uburyo bwo gushushanya buzenguruka.

(2) Ikwiriye gukorwamo ibikoresho bya pulasitiki by’ubwoko bwinshi n’ibito- bitewe n’imiterere yoroshye n’igiciro gito cy’ibumba ryo gushushanya rizenguruka, biroroshye cyane guhindura ibicuruzwa.

(3) Ikwiriye gutunganywa mu gutunganya ibicuruzwa binini bifite imiterere igoye, bitagereranywa n'izindi nzira zo gushushanya;

(4) Biroroshye guhindura ibara ry'ibicuruzwa bya pulasitiki. Iyo ibara ry'ibicuruzwa rikeneye guhindurwa, ni ngombwa gusa gusukura icyuma cyo gushushanya.

(5) Ingaruka mbi z'ingenzi zo gushushanya ku buryo buzunguruka ni: gukoresha ingufu nyinshi, kuko muri buri gihe cyo gushushanya, ibumba n'ishingiro ry'ibumba bigomba gushyushya no gukonjesha kenshi; igihe cyo gushushanya ni kirekire, kuko ubushyuhe bukorwa ahanini na pulasitiki idahinduka. , bityo igihe cyo gushyushya ku buryo buzunguruka ni kirekire; imbaraga z'umurimo ni nyinshi, kandi ubwiza bw'ibicuruzwa ni bubi.
