1	Development of a Particle Flow Test for Rotational Molding Whatcott, Russell B. 30 June 2008 (has links) (PDF) One of the current testing method (the Dry Flow test) to qualify resin for use in production in the rotomolding process has been shown to have many flaws in both equipment and procedure. Research was done here to investigate a possible alternative that could eliminate some of these testing deficiencies. By reducing equipment and operator errors, the testing of materials becomes more valuable of an exercise. The Angular Flow test developed in this research can increase repeatability. By coming to understand the rotational molding process better, an evaluation that can give more valid information was devised. dry flow test rotational molding quality testing material powder flow resin angle of repose funnel ASTM D 1895-96 rotomolding plastics hollow control Brent Strong quality assurance improved flow test flow test method Construction Engineering and Management Manufacturing
