You may be familiar with the different processes involved in the rotational molding. Based on the features and requirements of your product, you should work on a suitable type of molding machine. There will be several types of rotomolding machines with slight modifications in the features. Industries will use larger armed molds, while small-scale producers employ a lower-end version of the machine. Although they are all different machines, the basic concept will remain the same. In this article, let us discuss some of the types of rotational molding machines that are trending in the market.
Vital types of rotational molding machines
Rock and Roll machine
Rock and Roll molding machines are suitable for producing long parts that cannot be made with the help of low-end machines. It will eat a lot of space and is best suited for industrial purposes. You can witness two large sinning arms aligned at 45 degrees to each other. Every arm will be rotating around a particular axis, and each one’s end will be triggering the other arm to rotate in the other direction. There will be a complete 360-degree rotation. Some new machines will use hot air circulation to heat the molds.
Clamshell mold machine
Clamshell molding machine has the simplest design among all rotational molding machines., You can witness a single rotating arm that is supported by metallic supports at both ends. The machine contains both the cooling and heating chamber, and no mobility of the arms is required. Since the size of the machine is less, and there is an ease of operation, you can find the use of this molding machine in schools and labs for prototyping purposes. Also, some small-scale production can employ a clamshell mold machine.
It will come under the same small-size category of Clamshell molds. But here will be two rotating arms. Each arm will be moving in a to-and-fro motion passing the mold material between the hot and cold chambers. There will be no physical contact between the two arms, and they will be independently rotating on their axes helping the mold to coat and solidify on the mold. One of the applications of this type of mold machine may be the use in schools for lectures on the processes or prototyping.
You would be familiar with bi-axial molding processes and machines. They are the widely used molders, and Carousel is the most used one for industrial and private purposes. There will be rotation along two different axes, and more inner movement of the polymer material is possible, along with an excellent finish to the product. You can find two varieties of a Carousel machine as a fixed arm and an independent arm. The difference between the two is that in a fixed arm, the three arms will move together but in different chambers like heating, cooling, and loading (fixed to each other). But in an independent type, there will not be any connection between the three arms, and they can move freely.
