Abstract
Official abstract text for this publication.
A casing structure of electronic device including a metal base plate, a transparent cathodic electrodeposition paints layer, and a transparent paints coating layer is provided. The metal base plate has brushed texture and high gloss surface. The transparent cathodic electrodeposition paints layer is disposed on the base metal base plate. The transparent paints coating layer is disposed on the transparent cathodic electrodeposition paints layer. A manufacturing method of casing structure of electronic device is also provided.
First claim
Opening claim text (preview).
What is claimed is: 1 . A manufacturing method of a casing structure of an electronic device comprising: providing a metal base plate, the metal base plate has a brushed texture and high gloss surface; cathodic electrode positioning the metal base plate and forming a transparent cathodic electrodeposition paints layer on the brushed texture and high gloss surface; and spraying a transparent paints coating layer on the transparent cathodic electrodeposition paints layer, wherein the high gloss of the brushed texture and high gloss surface of the metal base plate is produced by the sequential processing of rough grinding, fine grinding, magnetic polishing, hemp wheel polishing and cloth wheel polishing. 2 . The manufacturing method according to claim 1 , further comprises: phosphating the metal base plate to form a transparent phosphating film on the brushed texture and high gloss surface before cathodic electrode positioning the metal base plate. 3 . The manufacturing method according to claim 2 , wherein the transparent phosphating film comprises zirconium compounds and resins. 4 . The manufacturing method according to claim 2 , wherein the manufacturing process of forming a transparent phosphating film comprises degreasing, warm water washing, water washing, film formation, warm water washing, pure water washing and drying in sequential order. 5 . The manufacturing method according to claim 1 , wherein the transparent cathodic electrodeposition paints layer comprises epoxy resins and acrylic resins. 6 . The manufacturing method according to claim 1 , wherein the transparent paints coating layer comprises acrylic resins. 7 . The manufacturing method according to claim 1 , wherein the metal base plate is a magnesium-aluminum alloy or a magnesium-lithium alloy. 8 . The manufacturing method according to claim 1 , wherein the brushed texture of the brushed texture and high gloss surface of the metal base plate is produced by drawing 320# nylon wheel back and forth twice. 9 . The manufacturing method according to claim 1 , wherein the manufacturing process of cathodic electrode positioning comprises hanging the metal substrate to perform pure water cleaning, electrode positioning, pure water cleaning and drying in sequence.
