Two-component water assisted injection moulding

Abstract

Two-component water assisted injection moulding (2K-WIT) is a new processing technology, fulfilling the high requirements of the automotive industry on media ducts on the one hand and offering a wide processing window and lower overall material costs on the other hand. The fundamental idea behind this technology is to split the requirements: mechanical strength, heat resistance, media resistance and channel surface quality into two groups. Each requirement group is then handled by a material which is tailored to fulfil these kinds of requirements. Schulamid 66 GF 30 2K WIT is used as the external skin material to achieve mechanical strength and temperature resistance. The inner wall surface is made out of polypropylene Polyfort FPP FX 2020 E, which offers perfect channel surface quality and ideal media resistance.
