Melting device and method for melting meltable plastic material, method for mixing reactive plastic components

A mixing arrangement, comprising:

• a mixing chamber capable of mixing reactive plastic components into a reactive mixture;
• a first melting device comprising a container capable of melting one of the plastic components supplied in a free-flowing state and storing the one of the plastic components in a liquid state, said container comprising a first storage section for storing the one of the plastic components in the free-flowing state, a second storage section for storing the one of the plastic components in the liquid state, and a dividing section provided between the first storage section and the second storage section and configured to hold back the one of the plastic components, when the one of the plastic components is in a non-molten or free-flowing state and to allow passage of the one of the plastic components from the first storage section into the second storage section, when the one of the plastic components is in a molten or liquid state;
• a first supply and dispensing section including a first vacuum conveyor for measured, continuous supply of the one of the plastic components in the free-flowing state to the first storage section;
• and
• a second supply and dispensing section for measured, discontinuous discharge of the one of the plastic components from the second storage section to the mixing chamber,
• wherein the first and second supply and dispensing sections are synchronised with one another so that only a prescribed quantity of the one of the plastic components is melted in the melting device, which quantity corresponds to an immediate demand for the one of the plastic components,
• wherein the first storage section and the second storage section are formed as one piece.
