The modern manufacturing industry is changing rapidly, brought about by innovations in material, production technologies and sustainability needs. With industries adopting more efficient processes that are smarter, technical education needs to follow suit and prepare the students with in-demand skills to match the current needs of industries. Rotational Molding is a very diverse process that has immense benefits in numerous industries and is therefore an aspect of the traditional manufacturing curriculum that should not be ignored.
CNC machining, injection molding and 3D printing form part of the disciplines that have been widely taught in technical programs worldwide. Although these are vital, an increasing number of people understand that there is a need to introduce a wider variety of manufacturing methods as part of courses in order to introduce the realities of the modern industrial environment to students. Rotational molding especially has become a major process that combines flexibility of design with durability and efficiency, but is often overlooked in many technical training curriculums.
Rotational molding (also known as rotomolding) is a process used to manufacture hollow plastic products. Rotationally molded products are manufactured by melting plastic material and by rotating a mold in a rotational molding machine until the interior surface of the mold is covered with an even layer of melted plastic. The end product is a smooth, strong but high strength product that finds utility even in high-end sector like automobile, aeronautics and consumer products. Industries such as Granger Plastics illustrate how rotational molding creates everything, including large storage tanks as well as custom-design components regardless of the required performance demands.
Addition of rotational molding in technical education is beneficial in a number of ways. First, it exposes students to real world production methods that go hand in hand with what industry demands, given the fact that manufacturers are also in need of a cost effective but durable means of production. The process also encourages the use of critical thinking in design, with products produced with rotational molding commonly needing creative solutions to the selection of the material, the design of the mold, and quality assurance.
Also, an increasing emphasis on sustainability is another reason why rotational molding is becoming even more applicable. The process results in little waste and facilitates easy usage of materials as well as the manufacture of durable and recyclable plastic goods. With industries around the world struggling to determine how to impact the environment the least, and industries learning the best way to manufacture in a responsible way, knowledge of such processes begins to play a vital role in responsible manufacturing education.
Rotational molding should be incorporated in technical curriculum, enabling students to have a better idea of the plastics manufacturing process as well as design opportunities. Graduates well versed with this approach will be in a better position to make contributions in the industries where strength, durability, and flexibility of the product is essential.
With the increasing need of innovative, sustainable production, schools can seize the chance to adapt. The integration of such processes as rotational molding will make students graduate with real-life experience to succeed in the modern manufacturing world.
