Existuj\u00ed dva druhy formovac\u00edho p\u00edsku: p\u0159\u00edrodn\u00ed v\u00e1zan\u00fd (b\u0159ehov\u00fd p\u00edsek) a syntetick\u00fd (jezern\u00ed p\u00edsek), kter\u00fd je obecn\u011b up\u0159ednost\u0148ov\u00e1n d\u00edky sv\u00e9mu konzistentn\u011bj\u0161\u00edmu slo\u017een\u00ed.<\/p>\n P\u0159i obou metod\u00e1ch se p\u00edskov\u00e1 sm\u011bs nap\u011bchuje kolem hlavn\u00edho \"vzoru\", kter\u00fd tvo\u0159\u00ed dutinu formy.

Pot\u00e9 se do dutiny formy nalije lic\u00ed kapalina (obvykle roztaven\u00fd kov). Po ztuhnut\u00ed a ochlazen\u00ed kovu se odlitek odd\u011bl\u00ed od p\u00edskov\u00e9 formy.

Vzduchem s\u00e1zen\u00e9 formy mohou vytv\u00e1\u0159et odlitky s mnohem hlad\u0161\u00edm povrchem.
