Co to jest?

At it core, high- speed compression molding is a forming process where a preheated charge of material - typically a termoplastic or termoset composite - is placed into an open mold cavity. The mold then closes rapidly undeid high pressure, forcing thee material two flow and fill every detail of thee cavity. Heat and pressore are maintained until the part coures or solidifies, after thee mold opend and the part iejected.
