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 for measured 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 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.

A method for melting meltable plastic material, comprising:

• supplying a meltable material in a free-flowing state to a first storage section of a melting device;
• melting the material in the first storage section of the melting device;
• storing the molten material in a liquid state in a second storage section of the melting device;
• discharging the molten material in the liquid state;
• and
• separating the first storage section and the second storage section such that the material in its non-molten or free-flowing state remains in the first storage section and, in a molten or liquid state, is capable to flow from the first storage section into the second storage section.

A method for mixing reactive plastic components, comprising:

• supplying a measured quantity of the reactive plastic components in a free-flowing state to respective melting devices;
• melting the reactive plastic components in the respective melting devices;
• supplying a measured quantity of the molten plastic components to a mixing chamber;
• mixing the molten plastic components with one another into a reactive mixture in the mixing chamber;
• and
• coordinating the supply of the reactive plastic components to the respective melting devices and the supply of the molten plastic components to the mixing chamber such that only prescribed quantities of the reactive plastic components are melted in the respective melting devices in correspondence to an immediate demand for the plastic components.
