Notes:
The production of automotive exterior body panels in the PUR-RRIM process is a comparatively new technology that provides a great potential for further improvements and makes it possible to produce plastic components for the automotive industry that, at relatively thin wall thicknesses, meet maximum requirements in regard to part geometrydimensional stabilitythe high industrial standards valid in the automotive industrysurface quality (avoidance of sink marks, pores, etc.)durable fastening For a better acceptance of RRIM moldings, cost reductions in the production process are necessary which, in turn, require noticeable progress in the material and process development. Due to the improvements made in the field of both raw materials and production units, the PUR-RRIM process has, in the last few years, become interesting also for high-volume production. A handicap in this connection is that the development of the RRIM process is, to a large extent, based on the practical experience of a few experts. For its use in high-volume production it is, however, inevitable to have at hand through scientific data on material, design, process and resulting correlations. It is the objective of the Institute for Polymer Testing and Polymer Science in Stuttgart to help establish these data and, through close contacts to the industry, make them usable in practice.
