I'm looking to develop a vehicle underbody component through the rotomolding process. Initially, I'm interested in producing a prototype to evaluate its performance and fit. If everything goes well, there's a potential for larger-scale production in the future. The approximate dimensions for the underbody are 3.3 m in length, 1.2 m in width, and 1 m in height. Could you provide insights on your capabilities for this project, including lead times, costs, and material options? Your input would be greatly appreciated as I move forward.
