Stiall Práis
Réamhrá Táirge
Bileog Práis bunaithe ar chopar leictrealaíoch, since agus riandúile mar amhábhar, trí phróiseáil le tinne, rolladh te, rolladh fuar, cóireáil teasa, glanadh dromchla, gearradh, críochnú, agus ansin pacáil. Feidhmíocht phróisis ábhair, plaisteacht, airíonna meicniúla, friotaíocht creimeadh, feidhmíocht agus stáin mhaith. Úsáidtear go forleathan é i dtionscail leictreacha, feithicleach, cumarsáide, crua-earraí, maisiúcháin agus eile.
