Everything You Need To Know About Rotational Molding

 

What is Rotational Molding?

Rotomolding or Rotational Molding is a process of manufacturing large hollow plastic articles. Machines involved in the rotational Molding are available in variant sizes. The whole process involves filling the mold with polymer, then heating, cooling, and unloading. 

Rotomolding process

Rotational Molding is a process in which plastic is molded to make hollow and one-piece products. This process involves four basic steps.

1. Filling the mold with a polymer which is in powdered form, into the mold.
2. Heating the mold in an oven while biaxially rotating it so that the polymer inside the mold melts down and sticks to the mold's surface. The matter of nitty-gritty is heating time. Heating the mold for too long will significantly reduce the mold's strength as it will start to degrade. Also, heating the mold for a short time will result in the formation of an incomplete product. 
3. Cooling, generally by a fan or spraying water while the mold still rotates, cools down gradually. Rapid cooling might result in shrinkage of the final product. 
4. Once the mold is cooled down, the molds are manually opened up by the operators. 

Advantages of Rotational Molding

• Pocket-friendly- Rotational Molding involves no pressure during the manufacturing process. This allows engineers to use elements like Aluminium, which are low in cost.  
• Environment-friendly- Rotational Molding is an environment-friendly technique. It involves no chemicals or harmful substances through-out the process. Minimal material wastage is promoted. 
• Lightweight products- A fantastic advantage of using these plastic rotomolded products is that they are light in weight compared to other materials, making them easy for transportation and installation.
• High strength- Rotational molding technique's base is to keep the product intact. No separate parts are added to it. Hence leaving no weak spots. It also has thicker walls to provide high strength.

In conclusion, we reckon you are impressed by the process since you have reached this article's end. Rotomolded products promise you durability and value for money. It is a package of advantages for you. Visit our website at the link given below. We would be happy to serve you.
