Rotational Molding, also known as Roto Molding, is a plastic molding technology for making hollow parts. It is a casting technique that is used, unlike most other processes where there is no pressure involved.
If you’re producing fewer than 2,500 pieces of product annually, you might be better off using roto-molding due to tooling costs. But if your production volumes are higher annually, Blow Molding should always be considered due to lower piece prices and overall project costs.
Blow Molding allows for greater design flexibility than rotational molding. Blow molding can produce a wider range of shapes and sizes, including complex geometries and thin-walled parts. Blow molding can also produce parts with high precision, which is useful in applications where dimensional accuracy is important.
Blow Molding is typically more cost-effective than rotational molding for large production runs, as the initial tooling costs can be spread out over a larger number of products. Additionally, blow molding is faster than rotational molding which can lead to increased productivity and lower overall costs.
