Rotational Molding Technology
by R.L. Crawford
and J.L. Throne
Features
- Clarifies and quantifies many of the technical interactions in the rotational molding process.
- Seamless story of the advanced aspects of the process.
The growth of the rotational molding industry has grown at 10 to 15% per year since the year 2000. With this growth has come an increasing need for details on the complex, technical aspects of the process.
Rotational Molding Technology clarifies and quantifies many of the technical interactions in the process. It distinguishes itself from other books on the subject by being a seamless story of the advanced aspects of the rotational molding process.
Contents
- Introduction to Rotational Molding
- A brief overview of the process and a comparison of rotational molding versus blow molding and twin-sheet thermoforming.
- Rotational Molding Polymers
- Describes the characteristics of polyolefins, which are the major class of polymers used in the process. It includes descriptions of vinyls, nylons, PVC plastisols, silicones, and thermosetting polymers.
- Pulverizing, Grinding and Attrition
- Focuses on particle size of solid polymer powders, particle size distribution, particle analysis techniques, and optimum particle shape. It also details pigments and property enhancers.
- Rotational Molding Machines
- An overview of the myriad types of commercial rotational molding machines.
- Molds
- Compares materials such as steel, aluminum, and electroformed nickel in terms of their characteristic strength and thermal efficiencies. It also discusses mold design aspects and various mold releases.
- Processing
- Covers powder flow behavior, particle-to-particle adhesion, and densification as well as bubble removal, oven cycle time, and other mechanisms.
- Part Design
- Provides an overview of the technical aspects that influence part design, including powder flow into and out of acute angles, and the effect of processing on properties and polymer characteristics
