Method of Manufacturing Metal Basket

A method of manufacturing a metal basket comprising:

• a step of preparing materials, wherein multiple first metal bars, multiple second metal bars, and at least two peripheral bars are provided;
• a step of initial welding, wherein the multiple first metal bars and the multiple second metal bars are stacked crisscross and are welded together so as to produce a grid frame which has a base and multiple surrounding sheets connecting with a rim of the base, and when the multiple first metal bars and the multiple second metal bars are stacked crisscross and are welded together, the at least two peripheral bars are welded with the multiple surrounding sheets respectively, wherein each of the at least two peripheral bars has two bending extensions extending from two ends of said each peripheral bar and over two ends of each of the multiple surrounding sheets respectively;
• in a step of bending, wherein the grid frame and the multiple surrounding sheets are bent, such that the multiple surrounding sheets of the grid frame are bent upwardly and are perpendicular to the base so as to form a body with an opening facing upwardly, and the two bending extensions of said each peripheral bar and the body are bent and are connected together so as to produce a holder having gaps;
• and
• in a step of re-welding, two bending extensions of said each peripheral bar of the holder are welded together.
