Liquid metal screen cloth and manufacturing method thereof

Abstract

The invention provides liquid metal screen cloth and a manufacturing method thereof. The manufacturing method comprises the following steps that a screen cloth mold is prepared; a high-temperature heating furnace capable of controlling the heating temperature precisely is prepared; pre-melted liquid metal alloy is added into the high-temperature heating furnace and heated to a preset temperature through the high-temperature heating furnace; the liquid metal alloy which is heated to the preset temperature in the high-temperature heating furnace is introduced into the screen cloth mold through an ejection unit; and after the liquid metal alloy is formed into the liquid metal screen cloth in the screen cloth mold, the liquid metal screen cloth is demolded and taken out of the screen cloth mold. The liquid metal screen cloth manufactured through the method is provided with a screen cloth body, and a plurality of holes penetrating through the screen cloth body are formed in the screen cloth body.

Description

technical field [0001] The present invention relates to a structure and a manufacturing method of a metal mesh cloth, in particular to a liquid metal mesh cloth with no mesh formed by using liquid metal and a manufacturing method thereof. Background technique [0002] Screen printing is an important tool for screen printing, and it can also be said to be an important basis for screen printing. The function of the screen plate is not only to form the pattern, but also to control the amount of ink permeated during screen printing; therefore, the structure of the screen plate itself has a great impact on the precision of printing, the thickness of the ink, and the penetration of the ink. big impact. [0003] The manufacturing method of the screen plate, firstly, a mesh cloth is fixed on a screen frame after being stretched through a certain tension. Next, apply a photosensitive emulsion on the mesh cloth and use the photosensitive emulsion’s chemical reaction to ultraviolet l...

AI Technical Summary

Problems solved by technology

The manufacturing process of this kind of mesh cloth is relatively easy and the thickness of the mesh cloth can be controlled by rolling. This kind of mesh cloth will form knots 93 where the warp and latitude lines 91 and 92 intersect, so it is made of this mesh cloth In addition to the shortcomings of uneven surface, the screen plate is also prone to warp and latitude displacement when it is scraped, which affects the quality of screen printing

[0006] The electroformed screen made of nickel alloy can overcome the above-mentioned shortcomings of the warp and weft mesh because it does not have a net knot. However, it has the disadvantage of insufficient structural strength. When the wire diameter of the mesh is required to be thinner, it is easy to There is a situation of insufficient tension and rupture

In addition, although the stencil made by laser cutting also has the advantage of not having mesh knots, the structure of the stencil is prone to residues, which will cause the problem that the ink cannot penetrate the ink during printing
