Rotational Molding How The Process Works And What It Makes

Linen carts

Rotational molding: in many ways, this production method is the unsung hero of manufacturing. Many different products can be made through a plastic molding company. These include — but are not limited to — rolling laundry carts, bulk containers, linen carts, plastic lockers, and much more. Many times, there products are made through the rotational molding process. Yet at the same time, many businesspeople and entrepreneurs don’t understand how important this process is, or how it even works. In order to understand why this process is so necessary to manufacturing, you should understand something about how it works. Once you do, perhaps you will be able to make a more informed decision about your manufacturing needs — thus saving time and money, and having the most efficient manufacturing process possible. Let’s look into some of the reasons why rotational molding may be the right process for your product — whether it’s a rolling laundry cart, a plastic locker, or something else entirely!

Rotational Molding: What It Is, And How It Works

So, how does rotational molding work in the first place? And for that matter, what is it? It’s a very unique process, and specialized for its particular purpose. Using heat, resin is melted and fused in a closed mold. While most plastic molding processes use pressure, pressure is not used in this process at all. It’s done in four stages, including loading resin into the mold, heating and fusing the resin, cooling, and finally unloading the part from the mold. There are different types of rotational molds, including CNC molds. The most expensive type of rotational molds, CNC molds are usually made in 6 to 8 weeks, depending on how complex the design is. It start with a 3D model of tooling halves that are CNC machined, before being ready to be framed and finished. Usually, you can expect a certain wait time for different processes, and should plan accordingly. Depending on not only the complexity of design but the approval process, the usual development wait time is six to 12 weeks for a tool build, one to three weeks for inspected samples, and one to three weeks for a finished part evaluation. This ends up being a total of eight to 18 weeks. This can depend heavily, again, on what you are having made.

What Can You Make With Rotational Molding?

The options for what can made through the rotational molding process are varied and diverse. Usually, they do serve practical purposes, like rolling laundry carts. Though we’ve mentioned rolling laundry carts a few times, don’t feel as if you’re limited to those products! The rotational molding process can create storage tanks — things that can be fairly small, or remarkably large. They can also form road signs, a far cry from storage tanks indeed. They can also form planters, or even pet houses. But don’t think that the process is limited to just that. Toys, bins, doll parts, helmets, footballs, kayaks, and more can be made through rotational molding. Essentially, if what needs to be made is plastic, there is a good chance that it can be created through the rotational molding process. Sometimes, the process is even used to create very specialized products, such as holding containers used by the UN.

Why Should I Use The Rotational Molding Process?

You may be thinking that just because this process is used by many others doesn’t mean it’s for you. Rotational molding is something that can, as we’ve covered, be used for many different purposes. It’s also cost-efficient. With just one mold, it can make a vast number of products. If you’re looking for quantity and quality, rotational molding has those two things in one process. It creates uniformity, and those that use the process can be sure that their products will be identical to one another, and made in a timely manner.

With the use of rotational molding, you can get the products you need, in the manner that you want.
