Plastic molding has come a long way in the last century. Today, anything, right from manholes to specific parts for machines, can be made using one form of molding or the other. While there are varied forms of molding, rotational molding is one of the new ones on the block. Typically, rotational molding is used for making hollow plastic products of all sizes with uniform walls. The use of rotomolding, as it is also called, is particularly popular for effective use of material, with little or no wastage whatsoever. From pet houses and recycle bins to containers, tanks and even slides, the technique can be used for producing varied kinds of goods – All you need is a reliable and known rotational molding manufacturer.
Decoding the process of rotational molding
The concept of rotational molding is rather easy on paper. The process also requires molds, which are first filled with a plastic resin material in powder form. The mold is then rotated and heated in an oven, which causes the plastic material to melt, and it would cover the entire inner walls of the mold uniformly. The mold is eventually cooled, which helps in solidifying the plastic, and the final product is taken out. Molds used for rotational molding are designed from softer and cheaper metals, such as aluminum, so it is easier to get additional logos and other brand-related information embossed on the end product.
One of the many advantages of rotational molding is the low tooling cost, especially if compared to molds that are made for injection molding. It is also possible to produce anywhere from 25 to 10,000 products in one go.
How to choose a company for rotational molding?
There are many companies that specialize in rotational molding, but to select one, you have to check what range of products they sell and their production capacity. Find more on their clientele and experience, and you can get an estimate for the order. When it comes to rotational molding, a company should be capable of handling orders and requests as required, and must work around a schedule to deliver on time. Ask in detail about the range or precision goods that they can produce, and don’t shy away from seeking client references.
With rotational molding, it is easier to get big hollow plastic parts without spending a fortune. Check online now for options and talk to a few manufacturers to understand their services better.
