Plastic molding has been around since 1800s, and there are a number of techniques that are in use, such as injection molding, compression molding, blow molding, and rotational molding. Each of these techniques have diverse applications and a few pros and cons. In this post, we will focus on rotational molding and its practical use for making different plastic products.

What’s rotational molding?

For the uninitiated, rotational molding involves placing liquid resin or plastic material in a mold, which is then placed in an oven and rotated at an even speed. This creates centrifugal force that creates even walls, and the material covers the entire inner surface of the mold. As a result, the products created with rotational molding are durable and strong. Typically, rotational molding is used for making large and hollow plastic parts, and it works exceedingly well for creating big containers, traffic cones and other large products.

A look at applications and advantages

Today, rotational molding is the preferred choice for manufacturers like fibertechinc.net that make durable and large plastic items. In contrast to comparable molding methods, this technique is cost effective, because the tooling costs are much lesser. The products created with rotational molding have even walls, and it is possible to make double-wall products easily. As mentioned earlier, rotational molding is highly useful for industrial and commercial plastic manufacturing needs, simply because the products created are much more durable and have thick corners. The process is such that additional textures and logos can be added easily to the final item.

Understanding the limitations

Like any other technique of plastic molding, rotational molding does have a few things on the flip side. For example, only selected materials can be used for making products with this technique, and the raw materials can be expensive, which means the cost per product can also increase. As far as production time is concerned, rotational molding needs more time, as compared to injection molding.

Great for industrial needs

Experts agree that rotational molding will remain the preferred technique for producing commercial and industrial plastic products that are often abused on a regular basis. A good example of that would be traffic cones or dumpster cans, and the possibilities with this technique are endless. If you want to place an order, make sure that you select a manufacturer who deals in rotational molding in particular and can offer an estimate in advance.
