Technical Field

[0001] The utility model relates to the technical field of injection molded shells, and particularly relates to a high-precision thin-walled injection molded shell. Background Art

[0002] An injection molded shell is a shell structure manufactured by an injection molding process. Injection molded shells usually have a certain wall thickness. When using a hydraulic injection molding machine, the basic wall thickness of most injection molded parts is between 0.8 - 3.2 mm. Usually, when the wall thickness is less than 1 mm, it is called thin-walled. Thin-walled injection molded shells have advantages such as being lightweight and saving materials in industrial applications, so they are widely used in many fields. Therefore, a high-precision thin-walled injection molded shell is used.

[0003] When the existing high-precision thin-walled injection molded shell is in use, it is not convenient to resist bending. Since it is a thin-walled shell, it is not convenient to resist external forces during use and is prone to deformation, resulting in a short service life. Summary of the Utility Model
