Ndi kuchuluka kwa ukalamba, magwiridwe antchito a polyurethane casters amataya ntchito pang'onopang'ono, zomwe zimadzetsa kulephera kwa zinthu. Pakugwiritsa ntchito, monga zida zosindikizira zomangira, zinthu zachikopa zopanga, mipando yamagalimoto ndi magawo ena, okalamba oponya ma polyurethane amatha kubweretsa ngozi zomwe zingachitike.

Chachitatu, kaya kukalamba kwa polyurethane kumapangitsa kuti zinthu zifewetse
Pambuyo pa ukalamba wa polyurethane caster, kuuma ndi kusungunuka kwa zinthuzo kudzachepa, zomwe zingayambitse kufewetsa kwa zinthu, koma iyi si njira yokhayo yosonyezera ukalamba. Mwachitsanzo, kuchepa kwa mphamvu zopondereza za polyurethane casters kungayambitse kusinthika kwa zinthu zomwe zikugwiritsidwa ntchito. Kumene, zizindikiro thupi ntchito monga kuuma ndi elasticity wa polyurethane casters kusintha pamaso ndi pambuyo ukalamba, amene ndi chimodzi mwa zizindikiro zofunika kwambiri za mlingo wa ukalamba chuma.
