An Overview Of Rotational Molding: Benefits, Process And More!

There are various techniques, called molding techniques, that are used for making plastic products. Rotational molding or rotomolding is one of them. Rotational molding is often considered for making large, hollow products, or for parts and plastic products that need stability, durability, and ideal wall thickness. Companies like Fibertech have been offering product parts and plastic goods that are made using this technique, and in this post, we are discussing some of the aspects that you need to know.

How does it work?

Rotational molding is a simplified process, where a hollow mold is filled with plastic resin. The mold is then rotated bi-axially in an oven, which causes the resin material to melt and cover the entire surface of the mold. The mold is then cooled down to harden the resin, and the final part is taken out. In this form of plastic molding, the focus is on high heat and lower pressure.

What are the benefits?

There are varied advantages of rotomolding. First and foremost, the cost of tooling is considerably lower, because molds can be made of cheaper metals, such as aluminum. With rotomolding, it is also possible to make products that have uniform wall thickness. Even complex hollow products can be made easily with this technique, and there is often no need of processing for the second time. Plastic parts that are made using rotomolding don’t require any additional techniques for joining, which adds considerable durability to the product. The risk of defects is minimized and products can be made with thicker corner for diverse applications. Finishes on the surfaces such as logos and other symbols can be easily incorporated as the tools and molds are made of softer metals.

Ordering for products using rotational molding

In general, rotational molding is used for making hollow plastic parts, such as tanks, storage containers, big recycling bins, pet homes and so on. Of course, to place an order, you have to find a company that specializes in rotational molding and can take both big and small orders. It is important to understand and decode the cost of using rotational molding over other techniques and evaluate if this is the right choice for your product requirements. Get an estimate in advance, and make sure that the manufacturer is a known one.
