IBM

Ndondomeko ya jekeseni kuwomba kukuumba (IBM) imagwiritsidwa ntchito popanga galasi lopanda pake ndi pulasitiki zinthu zambiri. Mukuchita IBM, polima ndi jakisoni wopakidwa pini yayikulu; ndiye kuti pini yapakati imasinthidwa kupita kumalo owumba ndikuumba kuti ipangitsidwe ndikuthira. Awa ndi omwe amagwiritsidwa ntchito pang'ono pazowumba zitatu izi, ndipo amagwiritsidwa ntchito kupanga mabotolo ang'ono azachipatala. Njirayi imagawidwa m'magawo atatu: jakisoni, kuwomba ndi kudzimitsa.

Makina opukusira jakisoni ali pa batala wa extruder ndi screw msonkhano womwe umasungunula polima. Ma polymer osungunula amadzidulira mu mawonekedwe othamanga omwe amawotchera pomwe amapakidwa kudzera mu nozzles mumkati wamkati ndi pini yapamwamba. Bokosi lamkati limapanga mawonekedwe akunja ndipo limamangidwa mozungulira pakati pa ndodo yomwe imapanga mkati mwa preform. Kapangidwe kake kamakhala ndi botolo / khosi lomwe limapangidwa bwino lomwe ndi chubu chokulirapo cha polymer, lomwe limapanga thupi. chofananira ndi chubu choyesedwa ndi khosi.

Kuumba kwa preform kumatseguka ndipo ndodo yoyambilira imazunguliridwa ndikugundana. Kutha kwa ndodo yoyambira kumatsegulira ndikulola mpweya wothinikizidwa ku preform, womwe umapangitsa kuti ukhale wofunikira kumaliza mawonekedwe.

Pakatha nthawi yozizira fumbi lachiwombo limatseguka ndipo ndodo yoyambilira imazungulira kuti ipangike. Cholemba chomalizidwa chimachotsedwa pakati pa ndodo ndipo ngati chosankha chitha kuyesedwa musananyamula. Chikombole cha kuwongolera ndi kuwombera chimatha kukhala ndi zingwe zambiri, makamaka zitatu mpaka khumi ndi zisanu ndi chimodzi kutengera kutalika kwa nkhaniyo ndi zomwe zikufunika. Pali magawo atatu a ndodo, omwe amalola kubayira jekeseni imodzi, kuwumba ndikuumba.

Ubwino: Imatulutsa jekeseni woumbidwa khosi kuti akhale wolondola.

Zoyipa: imangogwirizira mabotolo ang'onoang'ono okhala ndi mphamvu chifukwa zimakhala zovuta kuwongolera malo oyambira mukamawombera. Palibe kuwonjezeka kwa mphamvu yotchinga chifukwa zinthu sizitambasulidwa biaxially. Zogwirizira sizingaphatikizidwe.
