Chokulungira cha epuloni chimapangidwa kuti chiziteteza kusuntha kwa makina, monga lathe ya axis yambiri pamalo opapatiza kwambiri komanso mayendedwe osinthasintha amafunikira.

Ndi mitundu yosiyanasiyana ya zipangizo titha kupereka nsalu ya polymide yolimba kwambiri yokutidwa ndi NBR kapena polyurethane, mbiri ya aluminiyamu yokhala ndi hinge ya nsalu yokutidwa ndi NBR, mbiri ya aluminiyamu yokhala ndi hinge.

Kusinthasintha ndiye ubwino wofunikira kwambiri, ma apron roll-up amatha kukhazikika mu bokosi lachitsulo ndipo amatha kukhazikika mosavuta mu makina.
N'zothekanso kuyika chopukutira pa bokosi chomwe chingathandize kupukuta chip.
Epuloni yozungulira ingagwiritsidwenso ntchito ngati chitseko chozungulira kapena nsalu yotchingira.
