Inventor: Jiang Wei The present invention discloses a method for manufacturing a shutter assembly cloth rubber seal. The manufacturing process of the seal is as follows: The layered fabric-rubber composite material is placed in the mold cavity of a pre-shaped mold with a positioning pin fixed on the lower mold clamping cloth rubber composite, at room temperature with pressure Pressing machine (pressure 5 ~ 7 MPa). The preform is taken out of the preform mold, the blank is put into the door-shaped cavity of the lower mold of the forming mold, the preform is fixed with a fixing pin fixed on the lower mold,
