Plastic hollow part and method for the manufacture thereof

摘要

The invention relates to a plastic hollow part (1) and to a method for the manufacture of a plastic hollow part, wherein plastic material is introduced into a molding tool by means of a blowing or injection molding process, forming a hollow connection contour (10) and the plastic is formed into a hollow part (1), wherein a support ring (4) is molded into the area of the connection contour (10).

主权项

1. A method of producing a plastic hollow part, comprising:
providing an injection mold suitable for a blow-molding or injection molding process; inserting an annular support ring into said mold; inserting said hollow part into said mold in an interior of said annular support ring, with formation of a cavity between a connecting contour of said plastic hollow part and said support; securing positionally said support ring in said mold relative to said plastic hollow part in said mold; introducing a plastic filler material into said cavity by means of said blow-molding or said injection molding process to fill out said cavity; embedding said annular support ring into said connecting contour proximate to an end face of said hollow part by at least partially surrounding said annular support ring with said plastic filler material; wherein said securing positionally step includes the step of securing said support ring onto an outer surface of a split component; wherein before said introducing step the method further includes the step of moving said split component with said support ring into and against an interior of said plastic hollow part.
