Title: Manufacturing method for high precision mold

Abstract: A manufacturing method for a high precision mold comprises the steps of (a) placing a plastic body on a conductor substrate, (b) forming a plurality of perforating apertures in the plastic body using X-ray deep etching molding, (c) rounding the edges at the front end of the perforating apertures using ultraviolet (UV) lithography, and (d) electroforming the high precision mold using the plastic body with perforating apertures as a model. A fiber connector sleeve can be further manufactured by (e) molding a fiber aligning element using the high precision mold, (f) molding a fiber sleeve body using an usual mold, and (g) combining the fiber aligning element with the fiber sleeve body using ultrasonic waves to form the fiber connector sleeve.
