© Copyright Quest Industries Ltd Costs for product conversions from one material to another are reduced because rotomolding permits the replacement of heavier, often more costly materials with lighter, less expensive materials and does not require extreme or expensive tooling changes to switch materials. This advantage makes rotomolding as cost effective for one-of-a-kind prototypes as it does for large production runs. Rotomolding also offers significant design advantages in comparison to injection molding and blow molding. With proper design and engineering, parts that are assembled from several injection or blow molded pieces can be molded as a single part, eliminating expensive fabrication costs and streamlining the manufacturing process. In addition, rotomolding has a number of inherent design strengths, such as consistent wall thickness and strong corners that are virtually stress free. If additional strength is required, reinforcing ribs can be designed and molded into the part. | | | | |
