Monga pulasitiki yauinjiniya yotentha yokhala ndi zida zolimba m'zaka zaposachedwa, bolodi ya POM imagwiritsidwa ntchito kwambiri pantchito yomanga ndi kupanga. Anthu ena amaganiza kuti bolodi la POM lingalowe m'malo mwa chitsulo, zinki, mkuwa ndi aluminiyamu. Popeza POM board ndi pulasitiki yaukadaulo ya thermoplastic yokhala ndi malo osungunuka kwambiri komanso kuwala kwambiri, imayenera kusinthidwa ndikusinthidwa ikagwiritsidwa ntchito pazinthu zosiyanasiyana.
POM zakuthupi ali ndi makhalidwe a kuuma mkulu, kuvala kukana, kukana chinyezi, kukana mankhwala, etc. Iwo ali amphamvu mafuta kukana, kutopa kukana, mkulu zimakhudza mphamvu, mkulu kulimba, mkulu amakwawa kukana, wabwino dimensional bata, kudzikonda lubricating, Iwo ali mkulu digiri ya kapangidwe ufulu ndipo angagwiritsidwe ntchito kwa nthawi yaitali pa -40 mpaka 100 °C. Komabe, chifukwa cha kachulukidwe kakang'ono kachibale, mphamvu yamphamvu yotsika ndi yochepa, kukana kwa kutentha kumakhala kosauka, sikuli koyenera kuwongolera moto, sikuli koyenera kusindikiza, komanso kutsika kwapang'onopang'ono ndi kwakukulu, kotero kusintha kwa POM ndi chisankho chosapeŵeka. POM ndiyosavuta kuyimitsa panthawi yopanga ndikupanga ma spherulites akulu. Zinthu zikakhudzidwa, ma spherulite akuluwa amatha kupanga malo olimbikitsira ndikuwononga zinthu.
POM ili ndi kukhudzika kwapamwamba kwambiri, mphamvu yotsika ya notch, komanso kutsika kwakukulu kwapang'onopang'ono. Chogulitsacho chimakonda kupanikizika mkati ndipo ndizovuta kupanga mwamphamvu. Izi zimachepetsa kwambiri kugwiritsa ntchito POM ndipo sizingakwaniritse zofunikira zamakampani pazinthu zina. Chifukwa chake, kuti muthane bwino ndi malo ogwirira ntchito movutikira monga kuthamanga kwambiri, kuthamanga kwambiri, kutentha kwambiri, ndi katundu wambiri, ndikuwonjezera kuchuluka kwa ntchito ya POM, ndikofunikira kupititsa patsogolo kulimba kwamphamvu, kukana kutentha ndi kukana kukangana kwa POM.
Chinsinsi cha kusinthidwa kwa POM ndi kugwirizana pakati pa magawo a dongosolo lophatikizika, ndipo chitukuko ndi kafukufuku wa multifunctional compatibilizers ziyenera kuwonjezeka. Makina opangidwa kumene a gel osakaniza ndi in-situ polymerized ionomer toughening amapangitsa kuti gulu lophatikizidwe likhale lokhazikika lolumikizana, lomwe ndi njira yatsopano yofufuzira kuti athetse kuyanjana kwapakati. Chinsinsi cha kusintha kwa mankhwala chiri pakuyambitsa magulu amitundu yambiri mu unyolo wa maselo posankha ma comonomers panthawi ya kaphatikizidwe kuti apereke mikhalidwe yowonjezereka; kusintha kuchuluka kwa ma comonomers, kukhathamiritsa kapangidwe kake ka maselo, ndi kaphatikizidwe ka serialization ndi magwiridwe antchito komanso magwiridwe antchito apamwamba a POM.
