The rotational velocity in rotational molding is rather low (4 to 20 rpm). As a result, in the first stages of the heating cycle, the charged material remains as a powder layer at the bottom of the mold. The most convenient way of changing the cycle is by applying PU sheets in hot rolled forms. ... Crawford, R, Kearns, M, Practical Guide to ...
The DNA of Rotomolding by Roy Crawford, University of Waikato, New Zealand The early years of the rotational molding industry were dogged by a low technology image.
It distinguishes itself from other books on the subject by being a seamless story of the advanced aspects of the rotational molding process. There are seven chapters within the book. The US market for rotational molding products was one billion pounds in the year 2000. The growth of the rotational molding industry has grown at 10 to 15% per year.
