Zusammenfassung: | The present invention relates to a method for coating parts of electrical and electronic product manufacturing equipment using double sandblasting and polishing and to parts coated by the same method, whose purpose is to enhance durability such as adhesion strength (peel strength), anti-static properties, etc., of parts (clamps, grippers, etc.) used in equipment for manufacturing electrical and electronic products (devices, finished products, etc.) such as semiconductors and display panels through a combination of materials for elastic layer coating agents, surface treatment (surface roughness) of parts by double sandblasting, polishing, etc. The method of coating parts for electrical and electronic product manufacturing equipment using double sandblasting and polishing according to the present invention comprises: a first step of sandblasting the surface of the part two times repeatedly; a second step of washing the part surface-treated through the first step; a third step of forming an adhesive layer on the surface of the part after the second step; a fourth step of forming an elastic layer by coating a coating agent on the surface of the adhesive layer formed in the third step; and a fifth step of, after forming the elastic layer through the fourth step, adjusting the thickness by maturing the part at least once and flat-polishing the part. The first step includes a primary sandblasting step and a secondary sandblasting step. The primary sandblasting step is performed with a primary abrasive with a particle size of #80 ± 5 % at a spraying pressure of 3 to 8 KG/cm^2 for a spraying time of 25 to 35 seconds. The secondary sandblasting step is performed with a secondary abrasive with a particle size of #25 ± 5 %, which is larger than that of the primary abrasive, at a spraying pressure of 3 to 8 KG/cm^2 for a spraying time of 30 to 90 seconds to gradually widen the surface area.
