Problems solved by technology

The above-mentioned processing method with electroforming as the main process can only be used to manufacture a single-sided externally expanded metal micro-hole array, and the manufacturing process of the mandrel for electroforming is cumbersome, the mandrel cannot be reused, and the cost is very high
Although the mask electrolysis or photoelectrolysis process can obtain a single-sided or double-sided expanded metal micro-hole array, these manufacturing processes must prepare a shielding film with high shape and position accuracy and repeatability and contain a hollow structure array every time. , and it is coated on one side or both sides or closely attached to the workpiece (anode) to define th...

Embodiment Construction

[0028] Such as figure 1 Shown, the present invention comprises the following steps:

[0029] A: Use an inert metal sheet to make a template with the structure characteristics of a penetrating micro-hole group;

[0030] B: Closely fit the electrical insulation shielding layer on one side of the template;

[0031] C: Place the template in the electroforming tank. The side of the template that is not attached to the electrical insulation shielding layer is placed opposite to the electroforming anode. The template is connected to the negative pole of the electroforming power supply, and the electroforming anode is connected to the positive pole of the electroforming power supply. cast metal layer;

[0032] D: After the electroforming is completed, remove the electrically insulating shielding layer attached to one side of the template, and closely attach another electrically insulating shielding layer to the surface of the electroformed metal layer on the other side of the templa...

Abstract

The invention discloses a processing method for a double-side outward-expanded metal micro-hole array. By adoption of the characteristics that inert metal is hard to be electrochemically dissolved, an inert metal mold plate with a miniature through hole array is taken as a basis and is prepared to obtain high-performance double-side outward-expanded metal micro-hole array through an electroforming and electrolyzing combined technology. The method has the advantages of greatly reducing cost, simplifying technology and efficiently producing double-side outward-expanded metal micro-hole array with small aperture, high percentage of opening, and large thickness in batch.

Description

technical field [0001] The invention relates to a method for processing a metal microhole array, in particular to a method for processing a double-sided externally expanded metal microhole array. Background technique [0002] At present, metal structures with the characteristics of micro-hole arrays (divided into "filter", "screen" and "grid" according to different uses) are the core components of hydraulic, chemical, textile, powder, food and other applied industries. One of them carries important tasks such as high-efficiency filtration and particle sieving. Compared with woven mesh products, sheet-type metal micro-hole arrays have higher adaptability and practicability due to their various hole shapes, high profile precision, smooth wall surface, and good performance. mainstream in the field. However, the mesh axis section of the existing sheet-type metal micro-hole arrays is mostly straight-walled or cone-shaped, and the performance of passing objects (such as fluid, l...
