All About Producing Plastic Products With Rotational Molding

Plastic molding techniques and processes have evolved over the years. Even a couple of decades back, injection molding was quite popular, while compression molding is still used extensively for producing plastic parts that are supposed to replace the sturdy metal ones. Rotational Molding, also known to many as rotomolding, is one such plastic molding process that’s highly effective for producing hollow plastic products. It is considered to be one of the cost-effective choices, especially for companies and brands that need large orders with specific requirements. Below are some of the aspects worth knowing.

How does rotational molding work?

As compared traditional plastic molding, rotational molding works much better, especially for making hollow plastic products. The production process starts by making molds, which are customized for each order. Once the molds are done, ready, and approved, a liquid polymer material or powder is placed in the hollow mold, and the mold is then rotated in an oven bi-axially. This allows the resin to melt and cover/coat the entire inner surface of the mold. The mold is then cooled down, much like other plastic molding techniques, and the final product is taken out. Rotational Molding is a four-step process, but it allows extreme precision in the job, which is why it is one of the preferred methods of plastic molding.

Working with manufacturers

Many brands already have a mold for their products. In such cases, they contact the manufacturer and start the production process immediately after the prices and other terms and conditions have been discussed. You can also contact companies like www.fibertechinc.net, which have their own engineering teams to create molds according to requirements. This may come handy if you have a previous wooden prototype or need to improve on existing products. Of course, getting an estimate is a must. Some manufacturers also have the required expertise and resources to produce molds out of wooden or existing metal products. Basically, you need to be sure of your needs, and if the manufacturer knows what you need, getting the order ready shouldn’t take a lot of time. However, it is best to ask for a delivery date in advance.

Rotomolding is highly useful because there is minimal product wastage, as compared to other traditional methods of plastic molding. At the same time, you can produce a wide variety of materials, which is quite handy. Check online now to know more on rotomolding, and talk to a few manufacturers to get an estimate.
