The Sweetness of Rotational Molding

Rotomoulding

One of the best processes to create bulk plastics is rotational molding. Because roto moulders keep the plastic resin within it in nearly constant motion, the plastic takes shape evenly. Of course the benefit of evenly shaped plastic pieces is that you do not have to worry about the product coming out of the mold malformed, which faviconin turn saves both time and money. The other money saving element of using roto moulders is that you can meld various parts together very easily; roto moulders are capable of creating seamless products, so combining pieces is not difficult.

For the most part, rotational moulding is used to shape plastics made from polyethylene, polypropylene, polycarbonate, and nylon, though rotational moulding is also employed by those who wish to make products from metals like aluminum. But one of the more amazing uses for roto moulders, in my opinion, is their use in the candy industry. Rotational molding is used to make chocolates; specifically, it is used to make those little hollow chocolates we all know and love. Well, I love them, at least.

Similar to the process that is used to make plastics, roto moulders geared toward chocolate making are in part responsible for supplying children with their inevitable sugar highs during many holidays. The hollow chocolate bunny, ever-popular during the Easter holiday, is made with a roto moulder. The process is quite simple: you open the mold, pour in the chocolate, heat the mold, and make sure the mold stays in constant rotation to ensure that the chocolate coats the wall of the mold entirely. When you open the mold up after it has had time to cool, you have before you a perfect, hollow chocolate bunny. Bunnies are not the only hollow chocolates out on the market, of course, but they do seem to be some of the most popular chocolates you can make with a rotational moulder.
