Plastic materials are used for creating a number of different products for diverse industries. Plastic objects are created by molding these materials, for which unique techniques are used. Rotational molding, which is also called rotational casting, is one of the advanced molding techniques, which offers various advantages over plastic injection molding. In this post, we will talk about pros, cons, and other aspects in detail, but before anything else, let’s start with the process.

The process of rotational molding

Also called rotomolding, rotational molding is a relatively simple process on paper. The method is mainly used for creating large and hollow plastic parts. The primary material, which is either liquid resin or powder, is placed in a metal mold, which is then rotated in an oven. This allows the resin to coat evenly inside the mold, forming products with smooth walls. Once the rotation process is completed, the mold is then cooled down, and the hardened plastic product is taken out.

Benefits at a glance

Rotational molding is among the most cost-effective ways of molding plastic products. For plastic products, the cost of creating the initial mold is often high, which isn’t the case with rotomolding. The prices of the mold are much lower as compared to other techniques. Some of the other benefits include:

  1. Most of the available plastic molding techniques are suited for long run production requirements. However, with rotational molding, you can minimize a lot of your upfront costs, and thereby, this is a great option for short runs.
  2. Thanks to rotational molding, producing large and small parts is not hard at all. More than one kind of cavity mold can be used in each production run, which is a significant advantage. From creating smaller parts for specific industries to making large products like barrels, rotational molding offers a much better range.
  3. As mentioned earlier, this technique provides the best solution for making hollow products, including tanks, containers, covers, and much more. Manufacturers have ample flexibility to make products according to requirements, without losing on flexibility.
  4. With most plastic production techniques, material waste is a serious concern, but this isn’t the case with rotational molding. Contrary to what people believe, this process offers the scope to create almost any product, without losing plastic material, and that surely makes it a more eco-friendly production technique.

On the flip side, production runs can take a lot more time than other processes meant for plastic molding. With rotomolding, the choices for plastic materials are also limited.

Nevertheless, manufacturers don’t need to worry much about post production work, which is an added benefit, as the plastic products created are as specified. This is also one of the best options when it comes to getting custom products at lower prices. There are companies like FiberTech that can handle all kinds of production requirements, and you can be assured of getting quality products without additional expenses. The tooling costs are also typically lower, which only further reduces the costs. Check online to find manufacturers right now.
