Rotational Molding Brings Innovation to Lighting Products

Rotational molding, also known as rotomolding, is a manufacturing process used to create a diverse range of plastic products that are commonly used in day-to-day life. In recent years, rotational molding has rapidly increased in popularity and become a cost effective in the production of lighting products with a combination of highly functionality and great aesthetic impact.

Rotational molding process details

Rotational molding begins with a quality mold that is placed on an arm of a rotating molding machine that has a loading and unloading area, a heating oven and a cooling station. Several molds may be placed on the machine at the same time. A pre-measured amount of plastic pellet resin is loaded into each mold. The molds move into the oven where they are slowly rotated on both the vertical and horizontal axis. As heat penetrates the mold, the resin melts and adheres to the mold's inner surface until it is completely fused – no pressure is involved. The simultaneous heating and rotation evenly distribute the material on the inner surface of the mold, maintaining a consistent wall thickness. The mold is then cooled by air or water spray or a combination of both while still rotating. This gradually lowers the temperature. Once the parts are cooled, the finished part or case is removed and the mold is ready for the next cycle.

Benefits of rotational molding for lighting products

Cost effectiveness

In comparison to blow molding and injection molding, the tooling cost is inexpensive. The product cost is low as little material is wasted during the production.

Waterproof design

One of the greatest benefits of rotational molding is that the product is engineered to be watertight with one-piece construction. Some lighting products can even float on water.

Great design freedom

The great customization potential offered by rotational molding allows designers the maximum possibility of bringing their creativity to life. For this reason, the design of the lighting products made with rotational molding is always distinctive. In fact, the great freedom of shapes and sizes offered by rotational molding produces an alternation of lights and shadows that make the atmosphere rich and inviting. Moreover, this technology has the ability to produce the lighting products with complex and intricate geometries.

Customized surface and texture

Beside great freedom in the design, rotational molding offers wide possibilities of customization of surfaces, with different finishes. This opportunity represents a valuable resource for companies and professionals who develop design articles for lighting. In fact, each surface processes such as polishing, satin, embossing, knurling, give a special character to the diffused light.

Use durable and recyclable material

The polyethylene used in rotational molding of lighting items, and all other objects made with this technology, is resistant to chemicals UV rays and shock due to the additive technology. For this, rotomolded lighting products can be used without special precautions both indoors and outdoors, even being exposed to sunlight. They are durable to last for years, and also recyclable.

Versatility

One of the distinctive features of the lighting fixtures made with rotational molding process is the possibility of incorporating different functions. For example, lighting furniture is the ideal way to give an exclusive touch to the space that it is not only becoming a popular choice for trendy bars and restaurants, but also for home decor, adding a modern and ambiance look to the patio, or outdoor space.
