Wall thickness refers to the distance between two parallel surfaces of an injection molded part. It's a crucial design parameter affecting the part's structural integrity, appearance, and manufacturability. Proper wall thickness design is vital for successful injection molding.
Non-uniform wall thickness in injection molding can lead to a range of issues affecting both product quality and manufacturing efficiency. These variations can cause defects, cooling imbalances, and difficulties during the molding process. One of the most common problems resulting from non-uniform wall thickness is cosmetic defects.
The flow ratio (L/T) represents the relationship between flow path length (L) and wall thickness (T) in injection molding. It indicates how far molten plastic can travel within a given wall thickness. L/T ratio plays a crucial role in:
Considering the fact that LIB is prone to be short-circuited, shell material with lower strength is recommend to select such as material #1 and #2. It is indicated that the high strength materials are not suitable for all batteries, and the selection of the shell material should be matched with the safety of the battery. Table 3.
Traditionally, high strength is the priority concern to select battery shell material; however, it is discovered that short-circuit is easier to trigger covered by shell with higher strength. Thus, for battery safety reason, it is not always wise to choose high strength material as shell.
