In the 1920s, R.J. Powell pioneered the use of rotational molding to shape plaster of Paris, a soft blend of lime, sand or cement, and water. This material, named after the gypsum deposits found in Montmartre, Paris, marked the early days of the technique. By the 1940s and early 1950s, plastic rotational molding experienced another transformation with the advent of plastic molding. This method became popular for producing hollow plastic toys, particularly doll heads. The molding machines of this period were assembled from rear axles and other automobile parts, powered by electric motors, and heated by gas burners. Manufacturers used molds made of copper and nickel, which were cooled in water baths, predominantly working with PVC plastic.

Injection molding is a versatile process employed for shaping both plastic and metal. It utilizes a ram, hopper, heated barrel, nozzle, and mold. Here’s how it works: molten material is pushed by the ram through the heated barrel and nozzle into a cool mold. Once inside, the material conforms to the mold’s shape under pressure and rapidly solidifies. This method is notably quicker than rotational molding, particularly effective for producing intricate details like sharp threads.

Rock and roll rotomolders are specialized for creating elongated products. These machines are equipped with compact heating chambers and excel in high-volume production, ensuring efficiency. Depending on the specific needs, they may be outfitted with either a single or dual arm configuration. The primary arm rotates the mold 360 degrees around one axis and tilts it 45 degrees along another axis. Machines featuring two arms are referred to as shuttle type machines.

Note: Manufacturers have the option to procure raw materials from external sources or to handle poly processing on-site.

Engineers and manufacturers today employ advanced control and monitoring systems for cooling, initially pioneered in the 1980s at Queen’s University Belfast. They persistently innovate, exploring new materials and reimagining the rotomolding process, continually pushing the limits of what can be achieved.

There are five main types of rotational molding machines: carousel types, clamshell types, rock and roll types, vertical types and shuttle types.

Carousel rotomolders represent the predominant variety of bi-axial rotomolding machines. These machines typically feature either four or six stations.

Blow molding, akin to rotomolding, crafts hollow plastic components. In this method, melted plastic is shaped into a tube-like form with a hole at one end, known as a parison. Manufacturers then clamp the parison into a mold and introduce air through the hole. As the air enters, the parison expands until it conforms to the inner walls of the mold. Once cooled and solidified, the mold is opened, and the part is ejected. Primarily, blow molding is employed for manufacturing plastic bottles.

In 1976, delegates from multiple nations convened in Chicago, founding the Association of Rotational Molders (ARM), a global trade organization. Since then, ARM has grown to encompass members from 58 countries, fostering collaborative rotomolding efforts worldwide. Following ARM’s inception, engineers introduced innovative raw materials to its members, such as polycarbonate and nylon. These materials revolutionized industrial mold, water tank, and fuel tank production, enabling manufacturers to achieve significant advancements.

Rotationally molded plastics are thermoplastic products fabricated through the rotational molding process, or rotomolding. A thermoplastic is a plastic material that will soften when repeatedly heated and cooled. The rotomolding process is simple and inexpensive, involving only a revolving mold and high heat. Rotationally molded plastics are hollow, with the high tensile strength and uniform wall thickness due to single piece construction. Read More…

Rotomolding, while slower than other thermoplastic molding techniques, is generally used for shorter production runs. Despite its slower pace, rotational molding provides unique benefits not found in other processes. Firstly, it allows for simultaneous production of various products of similar sizes. Secondly, this method economizes on energy, tooling, and equipment expenses by eliminating the requirement for high-pressure molds. Thirdly, it facilitates quick transitions between different colored plastics without requiring extensive cleaning of production lines. Furthermore, seamless rotationally molded plastics exhibit enhanced durability against higher pressures without risk of fracturing.

When crafting a rotationally molded plastic part, manufacturers carefully weigh various application specifications. These include essential product traits such as strength, thermal durability, and flexibility. Additionally, considerations extend to desired product color, shape, size, and compliance with industry standards. Determined by these specifics, decisions are made on material selection—encompassing diverse plastic resins and additives—as well as the type of rotomolder and process employed.
