3、nd propose measures to improve the structure of parts or the prevention of defective。Secondly, According to structural characteristics of parts, technical requirements, production requirements, production volume, production conditions I choose methods of casting and modeling. According to the struct
4、ural characteristics of components, I develop a variety of pouring and parting programmes, analyse comprehensively and comparatively, choose the best pouring position and parting plan and develop a detailed programme of casting process. Again,according to the programme and structural characteristics of parts, I select the appropriate technical parameters , design feeding system and pouring system.of the casting ,map out the casting process plans. Finally, I design the casting process equipmen
