Why Rotationally Molded Plastics Matter
Plastic Rotational Molding
The plastics industry is perhaps the most important industry we deal with, however indirectly, on a day-to-day basis. Take a moment and think about all of the things you use every day that are made of plastic; it is a staggering thought. What is even more overwhelming is to imagine our world without plastics. One of the best processes the plastics industry employs to provide us with the products we rely upon so heavily is rotational molding.
Rotationally molded plastics are everywhere, from our vehicles to our potted plant holders. They make our lives easier. But why is rotational molding such a great way to create plastic products? One reason rotationally molded plastics are so popular is that molding them is relatively easy, when you compare how plastics are molded rotationally to other methods of molding. One of the most significant advantages of the rotational molding process is that it can reduce the number of steps required to make a molded piece. For example, if other molding processes require numerous steps to mold various pieces together, the rotational molder can fuse many pieces together at once. This of course cuts down on production time and possible waste of materials.
Because rotationally molded plastics are created in a process that saves both time and money, these products are usually less expensive for the consumer. This is perhaps one reason we love plastics so much. In addition, rotationally molded plastics are durable, as the molding process that produces them allows for more uniformity in the density of the plastic itself which translates into a stronger product overall. Other molding processes may heat and shape the plastic unevenly, resulting in weaker or thinner spots in the plastic; this, of course, can lead to problems for the consumer down the line. For ease of creation, benefit to the consumer, and cost effectiveness for the producer, rotationally molded plastics, I’m sure, will be in vogue for years to come.
