In the simplest terms, plastic molding involves a range of techniques that are used for making plastic parts. One of these techniques is known as rotational molding, or rotomolding. This is an extremely effective process for making hollow plastic parts, and there is little or no material wastage involved. Below are some of the aspects you need to know.
How does rotational molding work?
Well, the process of rotational molding is rather simple on paper. Powder or liquid plastic material is placed in a hollow mold, and the mold is then rotated bi-axially in an oven. This causes the material to melt and it coats the entire cavity of the mold’s surface. It is then cooled, and the plastic part is removed.
What are the benefits?
Rotational molding allows plenty of design flexibility, which is why it is often preferred over other techniques of plastic molding. The technique also reduces the number of labor hours required for the job, which helps in reducing the operational costs. Tooling costs are also much lesser than other methods, and the parts manufactured stand high in terms of durability and strength. The production process is much simpler, and you can get products with consistent wall thickness, which is often a requirement for certain plastic products. Rotomolding is also great for weight reduction of many plastic parts, which might be critical for engineering needs. You can learn more about rotational molding here.
Getting products made
There are companies that specialize in rotational molding, and you can expect all sorts of assistance as far as creating precision products are concerned. You can also check online to find a few of these companies. Tooling costs for rotomolded products usually differ based on configuration and size requirements. However, if you compare the costs with that of injection molding, you can save almost 70% or more, although a lot of things depends on other factors. If you know about your requirements, it is easy to get the work done, because most of the known manufacturers have their engineering staff, who can help and make your products compatible with the rotational molding process.
With the right approach, rotational molding can help in reducing the cost of producing plastic parts considerably. Find the right company online, and don’t forget to ask questions related to the production process. Also, it is a good idea to get an estimate in advance to understand the details better.
