Abstract
An arrangement for melting at least one solid precursor product for polymer production includes a housing for receiving the solid precursor product by way of an opening, and a melting device arranged in the housing. The melting device is disposed so that the solid precursor product can be fed thereto to be melted. A preferably switchable discharge device is connected to an opening of the housing and can be connected to an injection unit.
Claims22
A polymer molding apparatus comprising:
- a first polymer melting arrangement configured to melt a first solid precursor product for polymer production, said first polymer melting arrangement including:
- a first housing having an inlet opening for receiving the first solid precursor product;
- a first feed unit for feeding the first solid precursor product into said inlet opening of said first housing;
- a first melting device arranged in said first housing and configured to melt the first solid precursor product to produce a first melt material;
- and
- a first discharge device connected to an outlet opening of said first housing for controlling a flow of the first melt material from said first housing;
- a second polymer melting arrangement configured to melt a second solid precursor product for polymer production, the second solid precursor product being a different material than the first solid precursor product, said second polymer melting arrangement including:
- a second housing having an inlet opening for receiving the second solid precursor product;
- a second feed unit for feeding the second solid precursor product into said inlet opening of said first housing;
- a second melting device arranged in said second housing and configured to melt the second solid precursor product to produce a second melt material;
- and
- a second discharge device connected to an outlet opening of said second housing for controlling a flow of the second melt material from said second housing;
- and
- a molding tool connected to said first discharge device and said second discharge device by a conduit so as to receive both the first melt material and the second melt material from said first polymer melting arrangement and said second polymer melting arrangement, respectively;
- wherein each of said first melting device and said second melting device has a conical or pyramid shape oriented in a vertical direction and tapering toward said inlet opening of said first housing and said inlet opening of said second housing, respectively.
