Embodiment Construction

[0008] Please refer to figure 1 , the housing 1 includes a metal body 2 with honeycomb blind holes 3 on the body 2 .

[0009] Please refer to figure 2 The manufacture of the above housing 1 mainly includes the following steps: step 60 preparing a metal base, step 62 coating a protective film, step 64 forming pores on the surface of the protective film, step 66 etching and step 68 removing the film.

[0010] Wherein, the step 60 of preparing the metal matrix mainly includes blanking, stamping and post-processing and other processes. First, the metal sheet, which in this embodiment refers to an aluminum plate, is blanked according to the outline of the above-mentioned housing 1 to form several aluminum substrates, and then these aluminum substrates are stamped and formed in a punching machine, so that each substrate and the housing 1 have the same shape, form a three-dimensional surface and form openings according to the use requirements of the housing 1. The shell after sta...

Abstract

The invention is a cellular blind hole case making method, including the steps: preparing a metal base; coating protective film on the base surface; forming the arrangement of the blind hole according to the predetermined, and forming tmultihole on the protective film surface to expose metallic surface; etching the exposed metallic surface of the base so as to form blind hole on the base; eliminating the protective film to obtain the cellular blind hole structured case.

Description

【Technical field】 [0001] The invention relates to a method for forming pores on the surface of a casing, especially a method for manufacturing a casing with a honeycomb blind hole structure. 【Background technique】 [0002] At present, the method of forming a honeycomb blind hole structure on the surface of a solid workpiece is mainly a laser engraving method, such as the method for forming a series of continuous honeycomb structures on a solid surface used as a liquid transmission surface as disclosed in US Patent No. 5,143,578 , the solid surface is bombarded by a pulsed laser beam, and the solid surface is engraved to form a honeycomb structure. However, due to the limitations of laser engraving equipment and process conditions, it is difficult to form deep blind holes on the metal surface with this method, and the cost and energy consumption are high. 【Content of invention】 [0003] The purpose of the present invention is to provide a method for manufacturing a housing...
