Rotational molding is the most popular type of cavity wall construction and has been for decades. Most cavity wall construction uses rotational molding design guidelines for building cavity walls with rotational molding units. Rotational molding techniques include cold gas plastic injection, rotational rolling, direct metal roll molding (DML), and cavity-molded steel beam work. The process is also known as cavity-molded construction.
Rotational Molding Design
Rotational molding involves a hot air filled hollow cavity that is filled with either an injection or shot form of plastic. It’s then slowly rotating, creating the softened plastic substance to spread out and adhere to the walls of the cavity. This type of construction technique provides several advantages.
These advantages include a low minimum set up cost, long life, flexibility, high resistance to wear and tear, little mess after set up, excellent dimensional stability, little maintenance or set up required, easily available and affordable materials, easy cleanup, good spray coatings and other benefits such as anti-microbial protection.
The rotational molding technique was developed during the 1950s and has quickly become popular with builders and do it yourselfers rotational molding near me. One advantage of rotational molding is that it’s easy to make small models and get them into usable shapes. Another advantage of rotational molding is that it provides a precise and smooth mold for high-quality products that can be easily injected into molds.
There are several other benefits of rotational molding that can be incorporated into your design; such as the ability to create internal channels and airtight seams. Because the plastic injection molding process is very simple, and do it yourself can quickly and easily develop a number of different designs suitable for specific projects.
