Method of producing molding material

摘要

The additive is supplied using a dosing unit (3). This is located in a channel section of the conveying unit (4) and/or following it. The raw material melt flows through or around the channel section. The dosing unit includes at least one dosing component, arranged in a recess of the channel section. Additive enters via an annular channel connected to the dosing component. It flows through the dosing component into the channel filled with the raw material melt, and or enters the channel section with raw material flowing around it. Numbers of dosing components are each surrounded by basic material of the channel section, hence separating it from its adjacent components. In this way, additive introduction takes place through distributed, discrete dosing components distributed over the circumference of the channel section. In the channel section forming the dosing unit, and/or in at least one connected channel section, mixing of additive and raw material is effected using at least one mixing component. Plasticizing and/or conversion of raw material into a raw material melt, is effected through heat supply to it. The heat is supplied especially by a heater (15) in the outer wall of the cylinder (5) and/or by introducing thermal energy through the extruder. The molding mass produced is supplied to further equipment for batch- or continuous working. The further equipment optionally includes a machine for: injection molding, extrusion, blow-extrusion, extrusion blow molding, blown sheet extrusion, profile extrusion, sheet extrusion, pipe extrusion, panel extrusion, foam extrusion or liquid silicon rubber (LSR) manufacturing processes. Further details of application processes and of equipment used are included.
