Rotational molding, or rotomolding, is a cost-effective way of making large, joint-free polymer containers. "Rotationally Molded Transit Cases: 8 Advantages" discussed what makes this process so useful. Here, we'll dive deeper into the details of the process. Cavity coating The principle behind rotomolding is pretty simple. A molten polymer is spread over the internal surfaces [...]The post Understanding Transit Case Rotomolding appeared first on Sierra Cases.
