Key Analysis
Filter mesh refers to small aperture metal mesh or other materials with smaller apertures for a variety of different filtration, dust removal and separation requirements. They are widely used in shower panel, sanitary pipe systems, purifiers, electronic components, to remove contaminants or in applications, such as coffee machine, soya milk machine, to extract a filter cake. Because the metal mesh filters are one of the most durable filter media available, the material is mainly made of copper, iron, steel, nickel, stainless steel, alloy. It is acid resistant, alkali resistant, temperature resistant and wear resistant.
We customize diverse patterns metal microporous mesh with drawings provided by customers. We are equipped with professional metal etching equipment and exposure development equipment. Chemical metal etching filter mesh is a double-sided and simultaneous processing technology, which can make the product surface (positive and negative) smooth, without bumps, pits, burrs, warps, and flat mesh without deformation. Below are the advantages for customized metal filter mesh:

The High-tech LED Industry Research Institute (GLII) believes that Sanan Optoelectronics will be required to enter the main Taiwanese enterprise or for its development. Although there are many questions raised by the research institutions and the media about the actual effect of the incident, this incident is more beneficial than the disadvantages of both the main body and the development of the mainland LED industry.
Compared with unlisted LED display companies, the operating status of listed LED display companies is much better. Among the five listed LED display companies, Alto Electronics' net profit growth and gross profit margin were the highest in the first three quarters, and the gross profit margin remained at 42.66% in the first three quarters of this year. The Alto Electronics won a huge order of 200 million yuan from China Xinhua TV Holdings Co., Ltd., which not only increases the company's expected revenue, but also enhances the company's brand influence and market competitiveness.
In the second half of this year, Qinshang Optoelectronics issued the largest number of winning bids in all LED listed companies, but its share price decline since the fourth quarter was the largest among all LED listed companies. On the one hand, the company's performance still maintained but not as expected. The winning bidder will be converted into a real income cycle; on the other hand, the stock will face the largest lifting since the listing in the second half of this month.
GLII released "China LED chip industry regional pattern analysis (four)", the number of LED chip companies in Fujian, Jiangxi and other southern regions accounted for 24% of the national total, MOCVD installed accounted for 43%, and the output value accounted for 38%.

One of the most significant advantages metal mesh has over most filter media used today is its ability to deliver an adequate flow rate. This is achievable as the wire diameter and mesh opening can be customized to perfectly match the contaminants you are filtering out, providing you with an enhanced level of filtration surface area.
Durability
300 series stainless steel is predominantly used. This helps create a filter that can withstand a wide range of impurities, pressure variations, and extreme temperatures without hindering the filter's accuracy. In addition, stainless steel is a very pliable material, allowing the filter to be formed to fit your filter system and hold its shape after several uses.
Accuracy
The weaving process used to construct mesh filters is heavily monitored from start to finish. As a result, the pore openings of the filter are exact and uniform throughout the filter. These precise pore opinings ensure that the end product, whether a filtered substance or a filter cake, is consistent and complies with industry standards.
Clean ability
As metal mesh features accurate pore openings, blinding and plugging are significantly reduced. This, combined with the enhanced flow rate, means system operators can clean the metal mesh easily. These two properties allow the mesh filter to be backflushed and purged of any unwanted debris with minimal pressure.
