Stráice Práis
Réamhrá Táirge
Bileog Práis bunaithe ar chopar leictrealaíoch, since agus riandúile mar amhábhar, trí phróiseáil ag tinne, rollta te, rollta fuar, cóireáil teasa, glanadh dromchla, gearradh, críochnú, agus ansin pacáil. Feidhmíocht próisis ábhar, plaisteacht, airíonna meicniúla, friotaíocht creimeadh, feidhmíocht agus stáin mhaith. Úsáidtear go forleathan é i dtionscail leictreacha, feithicleacha, cumarsáide, crua-earraí, maisiúcháin agus tionscail eile
