[0002] Molds are various molds and tools used in industrial production to obtain the desired products through methods such as injection molding, blow molding, extrusion, die casting or forging, smelting, and stamping. In short, molds are tools used to make molded objects and are known as the "mother of industry."

[0003] The encapsulation process is to soften the encapsulation material into soft glue and cover it on other products to be encapsulated. That is, the products to be encapsulated are fixed on the encapsulation mold, and then the molten glue is injection molded onto the products to be encapsulated at a suitable temperature, and the products are obtained after cooling. However, since the products to be encapsulated are easy to move during the placement process, it is impossible to accurately place them in the corresponding position, resulting in difficulty in encapsulating the products or the encapsulation is off-center, and the quality of the products is unstable.
