The production of numerous products uses plastic as a material. However, it is possible to manufacture plastic in different ways, including the rotomolding process, a system that is gaining more and more popularity due to its advantageous characteristics. Understand why rotomolded plastics are ideal for your production process.
Using this technique, it is possible to create plastic items in different sizes, such as small basins and large reservoirs.
In today’s article, check out the benefits that rotomolded plastic offers to industries and understand why rotomolding is superior to other methods available on the market.
What are rotomolded plastics?
It is the fastest growing type of plastic transformation in Brazil and the world. After all, this process makes it possible to create large items, such as plastic pallets, something that is generally difficult to obtain in other industrial processes.
Rotomolded plastic can serve different market sectors, such as:
- Logistics;
- Food;
- Agriculture;
- Civil construction;
- Environmental;
- Pharmaceutical;
- Chemical;
- Refrigerator;
- And many others.
The technique consists of introducing powdered resin into a hollow mold, which is heated and rotated at a low speed. This way, the resin spreads over the entire length. As it melts, the polymer fills the entire mold, acquiring its shape. When it cools down, the piece is ready.
What is injection molding?
Injection molding works by injecting molten thermoplastic into a mold, as this method is highly complex and needs to be produced in a detailed manner to manufacture high-quality parts.
Additionally, due to the high temperature and pressures involved, molds must be machined from metals. Those made from aluminum are softer and less expensive, however, they show higher wear.
Another point to highlight is that certain geometries significantly increase the cost. This is because the creation of new injection molds tends to take months to complete and the costs are very high.
What is extrusion molding?
In this method, the die pushes the plastic, creating the final shape of the part. Extrusion machines are cheap when compared to other industrial machinery. Because they are simple, the matrices also have a lower cost.
However, the shapes and contours produced by the extrusion process are limited to products with continuous profiles, such as T, I, L, or U cuts.
Benefits of rotomolded plastics
Rotomolded plastic products have exclusive advantages when compared to items produced using injection and extrusion processes. Check it out:
- Resistant and 100% recyclable;
- Allow the use of additives, such as antimicrobial and UV14 protection;
- These are monobloc pieces, without corners, light and with a smooth surface, which guarantees greater versatility and ease of cleaning;
- Long useful life, which can exceed, on average, 10 years;
- You can customize them in shape and color.
