Kuyenda Molunjika pa Pultrusion
Kuyenda Molunjika kwa Pultrusion kumachokera ku kapangidwe ka silane kolimbikitsidwa ndi kukula kwake. Ili ndi umphumphu wabwino,
Kunyowa mwachangu, kukana kukwawa bwino, kusakhala ndi fuzz yokwanira; kusagwirizana bwino ndi polyurethane resin, kumapereka mawonekedwe abwino kwambiri a makina kapena chinthu chomalizidwa.

Kuyenda Molunjika pa Pultrusion
Kuyenda Molunjika kwa pultrusion kumagwirizana kwambiri ndi ma polyester osakhuta, vinyl ndi phenolic resin systems. Zinthu zoyenda zimagwiritsidwa ntchito kwambiri m'mafakitale omanga, olumikizirana, komanso oteteza kutentha.
Zozungulira, mphasa zimakokedwa kudzera mu bafa yothira utomoni, die yotentha, chipangizo chokoka mosalekeza, pansi pa kutentha kwambiri komanso kupanikizika kwakukulu, kenako zinthu zomaliza zimapangidwa pambuyo pa kudula.
njira yopukutira
Pultrusion ndi njira yopangira yomwe imapanga mawonekedwe a polima olimbikitsidwa okhala ndi gawo lokhazikika. Njirayi imaphatikizapo kugwiritsa ntchito chisakanizo cha utomoni wamadzimadzi, chomwe chimaphatikizapo utomoni, zodzaza, ndi zowonjezera zapadera, pamodzi ndi ulusi wolimbitsa nsalu. M'malo mokakamiza zipangizozo, monga momwe zimachitikira potulutsa, njira yopukutira imaphatikizapo kuzikoka kudzera mu chotenthetsera chachitsulo chotentha pogwiritsa ntchito chipangizo chokoka chopitilira.
Zipangizo zolimbikitsira zomwe zimagwiritsidwa ntchito zimakhala zopitilira, monga mipukutu ya fiberglass mat ndi ma doffs a fiberglass roving. Zipangizozi zimanyowa mu utomoni wosakaniza mu resin bath kenako n’kuzikoka kudzera mu die. Kutentha kuchokera ku die kumayambitsa njira yolumikizira utomoni kapena kuumitsa, zomwe zimapangitsa kuti utomoniwo ukhale wolimba komanso wokhazikika womwe umagwirizana ndi mawonekedwe a die.
Kapangidwe ka makina opukutira zinthu (pultrusion machines) kamasiyana malinga ndi mawonekedwe a chinthu chomwe mukufuna. Komabe, lingaliro loyambira la njira yopukutira zinthu (pultrusion process) likuwonetsedwa mu chithunzi chomwe chili pansipa.
