The invention discloses a fine net size forming method for a winding housing. A mandrel, a mandrel cylinder section, a front end socket cover plate and a rear end socket cover plate are manufactured,the mandrel is assembled, a gap is filled, a front end socket blank and a rear end socket blank are mounted, the mandrel is detected winding is detected, coiling and pre-curing are carried out, the mandrel is disassembled, and the fine net size winding housing is obtained. The winding mandrel cylinder section is made of a metal material, and compared with a wood mold and a plastic mandrel, the durability is greatly improved; the roughness of the outer surface of the metal mandrel cylinder section is far larger than that of a gypsum mold, the wood mold, a sand mold and a plastic mold, and the heat insulation molded surface in the winding housing produced by taking the metal mandrel cylinder section as a fetal membrane is smooth; the mandrel cylinder section made of the metal material is lowin cost and high in envir
