Definition of Rotomolding. Rotational Molding is the process of making durable and resistant plastic parts on a large and small scale, a thermoplastic process. With this process, plastic components and parts can be manufactured for any industry, and many advantages make it stand out above other similar processes. Understanding rotomodeling involves understanding each of its manufacturing stages following this step by step.
It is not a new technology; on the contrary, its beginnings date back to the sixties. In this decade, the first advances were made in a process that continues to be useful to the most diverse plastic industries. Many other technologies have been developed since then, but none has been able to beat Rotational Molding in many ways.
To learn more about the process, you have to go to its uses and functionalities, as well as the differences with other similar processes. These other processes are plastic injection molding, blow molding, and thermoforming, among other industrial processes. It is known that each of these processes can somehow be replaced by the Rotomolding Process but never the opposite.
Process description
The entire rotomolding process begins with the design; the prototypes or parts must be created using certain predefined criteria. The design process involves not only designing the part to be built but also the mold in which it will be made. Once the design is defined, the manufacturing stage begins, which in turn consists of about four stages:
- Loading Stage: the material with which it is going to be made is emptied into the mold, sealed and rotated to spread it evenly.
- Heating stage: the mold is brought to the heating chamber where the resin is rotated, distributed, and fused.
- Pre-cooling and cooling stage: the mold is cooled with water or air injection to gradually lower the temperature.
- Unloading stage: in this Stage, the finished product is removed from the mold, and it is cleaned to continue production.
Advantages of rotomodeling
Many manufacturers prefer Custom Rotomolding over other processes due to the resistance and strength of products made with this technique. Much of the manufacturing process is done so that the products are hollow and can be filled with foam. They also allow designs to have curves and rounded contours for a more aesthetic and pleasing appearance.
But undoubtedly, the primary factor remains the strength of the model thanks to the manufacturing, Molding, and design process. Manufacturers of all kinds of plastic parts invest in Rotomolding Design because they know that they will be able to make the most of it. The advantages of working with this technology are innumerable, and more and more industries are adding to the trend of rotomodeling.
To whom to turn
To produce and manufacture plastic parts with rotomodeling, you must go to specialized manufacturers with experience and experience. Not all manufacturers have the ability to produce from a small part to a large structure in small or large quantities. Finding the one with the highest production capacity is the smartest decision to make sure you get what you need.
Consult the experts before deciding who you will work within your designs and manufacturing of parts and components for your industry. Only the best will offer you the best service and the best care.
