Problems solved by technology

[0002] At present, in the production of fan blades such as CPUs, the injection molding method is commonly used, and the production efficiency is fast. If the molds usually used are in mass production, their structures are more complicated. When the structure is more complicated, it will bring many problems in the design, such as : 1. The uniformity of heating; 2. The distribution of vent holes; 3. The distribution of feed ports. If the above problems are not handled properly, the qualified rate of the product will be reduced.
