Rotational molding offers design advantages over other molding processes. With proper design, parts assembled from several pieces can be molded as one part, eliminating high fabrication costs. The process also has inherent design strengths, such as consistent wall thickness and strong outside corners that are virtually stress-free.

For applications such as rotational molding, polyethylene has to be used in powder form, however, the useful particle size of such powders is below about 2 mm, preferably below about 1 mm. More particularly, such powders have a particle size in the order of about 0.5 mm, that is 0.3 mm to about 0.6 mm.
Rotational molding techniques, also referred to as rotomolding or rotational casting, can be used to make hollow items of any size and of any desired shape. The rotational molding process uses plastic powder to form a desired product. The mold is placed in an oven applying a biaxial rotation until melted plastic covers all parts of the mold to ...
Rotational molding systems, including both the basic molding machines and the auxiliary equipment, are significantly improved. GRINDING Attrition mills are a common type of equipment used to make rotational molding powders. Pellets are pulverized between two serrated or otherwise simple rough disks, which have a close toler-
The mold is heated externally and then cooled while being rotated. Included in polymers useful in rotational molding are a variety of polyolefins such as polyethylene including crosslinkable polyethylene. A general discussion of rotational molding is given in "Modern Plastics Encyclopedia 1979-1980", Vol. 56, No. 10A, beginning at page 381.

Rotational molding is a manufacturing process of hollow articles. Figure 14.18 shows a schematic diagram of the process. The process begins with the introduction of a preweighted quantity of polymer, in either powder or liquid form, into half of a cold mold.
Particle size reduction, or grinding, is a process to produce a polymer powder necessary for a particular industry or technology. This can be accomplished by starting with resin pellets or a powder that is ground to a finer powder. At Ancos, we can achieve a range of desired size distributions to meet specifications, from coarse to fine.
