摘要： The invention relates to processes for the production of a composite component via multicomponent injection molding, where the composite component comprises a main body composed of a thermoplastic and an external layer composed of a foamed thermoplastic. The main body is produced via injection molding and subsequent hardening of the thermoplastic. A mixture of the foamed thermoplastic and a chemical blowing agent is injected onto the main body, subsequently hardened in the same injection mold, and foamed by heating. The composite component is solidified via cooling. The foamed thermoplastic is at least one polyamide whose modulus of elasticity is from 1 MPa to 250 MPa in the entire temperature range from 70° C. to 180° C. The chemical blowing agent is in non-polymerized form.

摘要： A pelletizing die for a pelletizer comprises a base body with holes for melt to pass through; the holes are disposed in rows. Allocated to the holes are wearing-protection inserts, having holes which are in alignment with the holes in the base body. The inserts which are disposed to adjoin each other in a row have a chordal surface where they are turned toward an adjoining insert and are provided with at least one surface of an arcuate segment of a cylinder laterally of the chordal surface.
