But the process has not been especially advanced. More modernized machines, molds, and controls, and a growing range of suitable materials are expanding rotomolding's application potential.
Rotational molding presents color manufacturers with numerous difficulties.
Yet, the market is demanding increasingly high color standards for finished products. The authors describe the rotomolding process and explain the factors affecting color production for this industry. Considering the Options 29 M. Kontopoulou, E. Takacs, C.T. Bellehumeur, and J. Vlachopoulos Although, theoretically, every thermoplastic with a suitable viscosity should be processable by rotational molding, commercial scale rotomolding of many such materials has not been possible. The authors present the results of mechanical property tests and sintering experiments in order to compare the characteristics of a variety of resins that are candidates for this emerging market. Having survived its growing pains, the rotational molding industry is poised for its third major expansion.
