Muchina unomonereka firimu imhando yekurongedza nzira inoputira zvinhu zvakasimba kuti zvitakurwe uye zvichengetedze pasi petembiricha yakajairwa nekushandisa deformation stress inogadzirwa nekumanikidza kutambanudza kwefirimu nemuchina wekutambanudza mudziyo kana ruoko.Iri fomu rakakurumbira rekurongedza munyika.Inotengeswa kunze resin uye advanced flow diffractive firimu extrusion process inogamuchirwa.Iyo ine hunhu hweiyo yakanaka tensile pfuma, kubvarura kuramba, yakasimba kupinda mukati, kujeka kwepamusoro, yakanaka yekuzvinamira chivakwa, yakakwirira yekudzosa chiyero, kurongedza kwakasimba uye pasina kusununguka.Inogona kushandiswa zvakanyanya kune imwe chete kana tireyi kurongedza uye kumwe kusungirira kurongedza kwemakemikari zvigadzirwa, makemikari mafetiraiza, chikafu, michina uye zvigadzirwa zvemagetsi, machira akareruka zvigadzirwa, nezvimwe.
