How is Rotational Molding Different than Injection Molding Process?

What is Rotational Molding?

When it comes to rotational molding, always consider layers. When you make a poly based product with the help of rotational molding process, the material and powered substances are added to the mold. Then the mold is bolted tight, put in an oven and rotated at an even speed. This is how the plastic has thin layers of even thickness, no matter if the mold has corners and curves. After the material is done baked, the plastic is cooled down inside the mold guaranteeing its even hardness and then is eventually extracted.

How is injection molding different from Rotational Molding?

When it comes to creating the injection mold products, the material is melted and forced slowly into the stationary mold in the high pressure. Then this process makes the use of pressure to evenly distribute the material in the entire mold making sure the coverage of the entire shape of the mold. When accomplished, both the molds are pulled apart and then the plastic is removed and cooled down. When it comes to Rotational Molding, Fibertech is the best choice amongst all.

Which is better of the two?

This process also has many advantages when considering commercial and industrial applications. There are many companies that make plastic dumpsters and carts for the waste industry. Besides, they are also exposed to extreme temperatures. As rotational molding processes give a more even application of the plastic material, the product you obtain is more flexible and durable in nature. In other words, it has very fewer odds of breaking or cracking up in extreme temperatures or when undergone by beating by waste handlers on their runs. Know that it is impossible to gain even wall thickness in injection molding process. These plastic injection mold products are always thinner in the corners and they cannot give the same amount of flexibility in the materials. In other words, they are not merciful when it comes to daily abuse in extreme temperature conditions.

Why is injection molding considered beneficial sometimes?

The process of injection molding has serious drawbacks but it has some benefits too. This manufacturing process can be compatible with more complicated mold designs and on the broader range of materials as well. The manufacturers can also make more items in the production line with the help of this very process which helps them in bringing down their production costs as well.
