Advantages of Rotational Molding
The underlying requirement for innovation is an understanding of the existing technical means for problem solving.
This section highlights some of the solutions made possible by ROTOMOLDING of thermoplastic and thermosetting resins. Rotational molding is a plastics processing technique that is ideally suited to producing relatively large, hollow, seamless parts which are partially or totally enclosed. Multi-Plastics Company utilizes the latest generation of rotational molding machines from industry leader Ferry Industries. Our state of the art equipment allows us to produce world class quality products in an efficient, cost effective manner.
In achieving the desired product characteristics material selection is a critical factor. A detailed engineering understanding of the impact of utilizing different rotational molding materials is an essential element in achieving design goals.
The nominal wall of the part is its basic frame that defines its shape. Once the basic shape has been established, other details can be added to provide other features in the finished part. Defining the parameters of the nominal wall is an essential element in the design.
Rotational molding provides the designing engineer with the unique capability to increase or decrease the wall thickness of a part after the mold has been built and sampled. The final wall thickness of the part can, therefore, be established after the actual in-use testing of the part. Few other plastics processing techniques offer the designer this advantage.
Advanced techniques have been developed for producing foamed parts with solid unfoamed skins on the outside or both inside and outside surfaces. Special molding procedures can produce composite parts that have two layers of the same material, different colors, or two layers of different materials. These additives and special molding techniques can be combined to produce very sophisticated parts.
Another recent innovation is the molder's ability to mold in single or multi color graphics during the molding process. These molded-in graphics are virtually indestructible and relatively inexpensive.
