Abstract

A system for production of a thermoplastic injection molding material granulate has at least one production unit for the production of a fiber reinforced plastic granulate from a thermoplastic granulate and natural fibers. to the system has at least one heat-treatment unit for the treatment of the fiber-reinforced plastic granulate providing heat such that an outer layer of each heated granulate grain of the fiber-reinforced plastic granulate is at least partially converted to a liquid physical state. The system has at least one applicator unit for applying a chemical foaming agent powder to at least some portions of each heated granulate grain, where the heat treatment unit is equipped to carry out the heat treatment such that a temperature of the molten outer layer of the respective granulate grain is below a reaction temperature of the foaming agent.
