Pawiri khoma kutentha shrink chubu amapangidwa ndi apamwamba polima (akunja wosanjikiza) ndi otentha kusungunula zomatira (mkati wosanjikiza) .Kutentha shrink tubing amateteza ku chinyezi ndi zowononga chilengedwe, pamene kupereka kusungunula magetsi ndi chitetezo makina. Poikapo, zomatira zamafakitale m'machubu ang'onoang'ono amasungunuka ndikugawidwa m'dera lonselo ndikupanga chotchinga choteteza, chosagwira madzi. Ikazizira pansi, wosanjikiza wamkati umapanga kusanjikiza pakati pa chubu ndi chigawocho kapena waya. Amapereka chisindikizo chopanda madzi komanso chitetezo kwa zolumikizira kapena mawaya.Kutentha kosalekeza kogwira ntchito ndikoyenera Minus 55°C mpaka 125°C. Palinso giredi yanthawi zonse yankhondo yokhala ndi kutentha kwambiri kwa 135 ° C. Onse 3:1 ndi 4:1 shrink ratio ndi zabwino.
