Cholumikizira, chomwe chimadziwikanso kuti mutu kapena wafer, ndi cholumikizira chomwe chimakhala pa bolodi losindikizidwa ndipo chimayenera kugulitsidwa pamapini ozungulira.
Zopatsira mapini wamba ndi: palibe maziko ophimba (mwachitsanzo: kapangidwe ka singano), chivundikiro choyambira (mtundu wawafer), mtundu wa loko ya mikangano.
Chogwirizira cholumikizira ndi cha pulasitiki yapadera ya chilengedwe cha kutentha kwambiri, ndipo chimayenera kukhala ndi kukana kutentha kwambiri.Mwachitsanzo, chotengera singano chomwe chimagwiritsidwa ntchito powotcherera pamwamba pa phiri chidzawotchedwa ndi zida zowotcherera, ndipo kutentha kumafika pafupifupi 265 °;China ndi chakuti mtundu wa pini umafunika kuwotcherera ndi zida zowotchera, ndipo kukana kutentha kuyenera kufika pafupifupi 230 °.Ngati kutentha pulasitiki sangathe kufika ndondomeko kuwotcherera zingakhudze ntchito yachibadwa mapindikidwe structural.
Cholumikizira zikhomo ntchito pulasitiki zopangira: nayiloni, poliyesitala, nayiloni, kutentha - PBT, poliyesitala - PCT, PPS, LCP, ndi zina zotero, liquidity osiyana ndondomeko akamaumba, pulasitiki chuma otaya kutalika, shrinkage, imbibition madzi, kukula liniya. coefficient ndi osiyana, mu pulasitiki nkhungu chitukuko ali zambiri kuchita ndi zipangizo ntchito ndi kuwerengera molondola.
