Is it scientific research experiment or large-scale production?1., you do not have the economic strength, or do not do, impeller production to do wood type, core box, drying. Casting processing, but also to do dynamic balancing, impeller casting rate is very low, you have to repeat the experiment many times in order to have a prototype,
You have the impeller, but also pump on the machine test, the scale of the factory will not cooperate with your experiment, and that the scale factory has a complete production process.
In doing research, popularizing knowledge, we should also invest fundsI don't know what kind of thinking you are
