1. Gukubita Molding: Ikirahure gishongeshejwe gisukwa muburyo bwateganijwe, hanyuma umwuka ukawujyamo unyuze mu gihu kugirango ubanze ukore icupa ryikirahure. Iyi preform noneho ishyirwa mubicuruzwa byarangiye, hanyuma umwuka ukongera ugahuha, bigatuma ikirahure cyaguka buhoro buhoro kandi gihuza neza nurukuta rwimbere rwububiko. Ibyiza byo guhumeka ni ubushobozi bwayo bwo gukora amacupa yikirahure yuburyo butandukanye hamwe nuburinganire bwurukuta rumwe, bigatuma bikwiranye cyane nuducupa twinshi cyangwa tworoshye -.
2. Gucomeka kwa compression: Ikirahure cyashongeshejwe kibanza gusukwa mubibumbano, hanyuma hakoreshwa igitutu cyumukanishi kugirango uhate ikirahuri mubice byose byububiko kugeza byuzuye. Icupa noneho riraka - risukuye kugirango rishyireho imiterere. Gushushanya gushushanya bikwiriye gusa amacupa yikirahure afunguye.
Ubuvuzi bw'icupa ry'ikirahure:
1. Inzira yubukonje bukonje
Ubukonje bwa Shimi: Ubukonje bwa chimique bukoresha igisubizo cyihariye cya acide kugirango gikore neza hamwe nu icupa ryikirahure, byangirika igice cyibikoresho byo hejuru kugirango bigere ku bukonje. Iyi nzira yo kwangirika ituma igenzura neza urwego nuburinganire bwubukonje, bigaha icupa ryikirahure imiterere idasanzwe yubukonje.
Guturika kumubiri: Guturika kumubiri bifashisha indege ndende - umuvuduko wibice byangiza kugirango bigire ingaruka kumacupa yikirahure, bigakora micro - imiterere itaringaniye binyuze mubukanishi, bikavamo ingaruka zikonje.
Guturika irangi: Guturika irangi bikubiyemo gutera irangi ridasanzwe ryakonje hejuru y icupa ryikirahure, bikora igifuniko gifite ingaruka zikonje.
