1. A method for producing a grinding liquid mixing tank, comprising the following steps:
providing a tank body made of polypropylene (PP) or polyvinylidene difluoride (PVDF), a bottom of the tank body having a conical arc-shaped wall, and the arc-shaped wall having at least one wall hole;
providing a rotor case made of polypropylene (PP) or polyvinylidene difluoride (PVDF), the rotor case including a bottom case wall, a side wall surrounding the bottom case wall, and a connecting wall connected to a top edge of the side wall, wherein the side wall has a thickness smaller than a thickness of the bottom case wall and a thickness of the connecting wall;
heating to soften the rotor case, and placing the rotor case into the at least one wall hole;
providing a jig to contact the rotor case, such that the connecting wall is deformed to be coupled to the at least one wall hole; and
welding a joint between the connecting wall and the at least one wall hole with a solder.
