Rotomolding cost depends on part size, mold complexity, surface finish requirements, frame design, and expected production volume. For water tank tooling, the mold investment is influenced by engineering time, casting requirements, machining, and finishing. A well-built aluminum mold can improve cycle efficiency, part consistency, and tool life, which helps lower long-term production costs over repeated runs.
