Abstract: As an important part of the hand generator, this main case is suitable to be produced through highefficient die casting with the center gate feeding method to produce high density castings. The main case casting that has working allowance at the secondary bearing housing and the rabbet along with an irregular contour can meet the precision requirements between the left housing and the internal and external rabbets of the right chassis, as well as between the bearing and the bearing housing after turning.
