Rotocasting Parts

We manufacture a diverse range of shapes and sizes for plastic rotomolding and rotocasting parts. Rotational molding is widely utilized across various industries to produce plastic products, including containers, crates, pallets, floats, water tanks, and more. Unlike most other plastic fabrication methods, rotocasting involves no pressure, making it ideal for creating large, complex shapes and capturing undercuts. This technique excels in producing durable, high-quality components with intricate geometries.

Rotational Molding Technology

For low-volume production runs and prototyping of large hollow parts, rotational molding technology employs a heated mold, typically made of aluminum or steel. The mold is closed and rotated slowly on two axes while being heated in an oven. The plastic rotomolding polymer material, in powder form, is placed inside the mold, where it gradually melts and adheres to the mold's interior surfaces. Once the polymer has fully melted, the mold is transferred to a cooling station, where it is cooled with air or occasionally a fine mist of water. As the mold cools, the polymer solidifies. When the material has sufficiently cooled to release from the mold surface, the process concludes, and the finished product is demolded.
