Specify the few dimensions that actually control assembly and explain their function. A single tolerance percentage for every rotomolded part is not a useful acceptance standard. Separate molded envelope dimensions from machined interfaces and hole positions. Agree when the part is measured, its support condition and the reference datums. Test the sample on the real mating equipment. A tool made accurately does not remove the influence of resin, pigment and cooling on the final part.

What to send for a useful review
- Critical interfaces, datums and tolerance
- Overall dimensions and installation space
- Resin grade, data sheet and batch traceability
- Test conditions and pass/fail limits
Agree acceptance before tooling
General guidance. Validate resin, geometry and assembly in actual operating conditions. This is not a product certification or production commitment.
Robot, AMR & AGV housings
Evaluate covers, bases and service enclosures for mobile robots. Large curved hollow forms may suit rotomolding. Mounting accuracy, cooling and sensor clearances need review. Precision frames, drives and safety systems require their own manufacturing routes.
