3, but a feature of energy saving work is just need to calculate pup, amassing, if not carefully, just to hope that by a few big technology to achieve the goal of energy saving is very unrealistic, thus completes the energy conservation work of the pressure is on to act immediately.First touch base, the establishment of system, clear objectives, only in this way can really completes the energy conservation work.Hexing precision casting factory is one of the main characteristics of many varieties and small batch production, in the same weight of qualified castings, exactly how much energy consumed, can not be directly obtained by calculation, but also to use and by improving the process parameters and process scheme, we can not improve the condition of existing hardware conditions greatly save energy consumption, such as increasing product rate of castings can also be used to improve yield and reduce the repair rate, optimizing production processes.
