A filtration system manufacturer was creating a filter assembly to meet a seawater regulatory specification with a 25-micron rating. They had already completed preliminary rounds of design approval before consulting with a mesh supplier, so they were already locked into a particular 25-micron weave.  The approval of that mesh was based only on its micron…

The demand for new renewable energy sources is giving rise to new-generation fuel cell development and hydrogen production using electrolyzers. Within this sector, wire mesh is one small component of the larger whole, but the right selection plays a critical role in the overall performance of the specified application. So, what exactly is its function,…

Wire mesh is a versatile material consisting of parallel rows and intersecting columns of wire. It comes in many different shapes, sizes, weave designs, materials and metal alloys for a number of industrial and manufacturing applications. Among the specifications used to describe wire mesh are the terms Nominal and Absolute retention rating, but what exactly…

Cold Bond™ is a unique metallic bonding process developed to stabilize wire mesh for batteries, fuel cells, green hydrogen production and other processes. Woven wire meshes are becoming key components in current and emerging electrical energy generation and storage technologies – serving as anodes and cathodes, catalytic surfaces, permeable membranes, or chemical deposition substrates.  In…

In part three we separate the possible from the practical and discuss manufacturability or forming of the wire mesh media to meet the shape of the filter design, and how it can affect the filtration properties of the wire mesh. As a recap of our series, in part 1, we discussed different mesh weaves and…

For this series on understanding wire mesh for filtration, in part one we discussed different mesh weaves and their roles in filter design.  Here in part two, we will consider factors that degrade mesh performance as it relates to mesh aperture. When choosing a micronic mesh for a filter application, key variables often overlooked are…

Selecting a micron wire mesh can be a daunting task. To better understand the complexities of mesh selection overall, let’s consider the more limited example of just choosing a 60-micron filtration mesh.  We will first discuss some of the variables in what you expect the mesh to accomplish, followed by a comparison of the ways…

What is the Lead Angle? The lead angle adjustment controls the path the material travels across the screen. In round vibratory separators, the lead angle can be best defined as the counterclockwise angle between the top and bottom weights when viewing the machine from above. When set to the correct lead angle, the material feed path…

Using a vibratory separator machine is a reliable method of sorting, classifying, and cleaning a wide range of materials, both dry and wet. Because the material is sorted through a wire mesh screen, some materials tend to clog the mesh openings, effectively limiting the capacity of the machine’s throughput. To avoid stopping the process to…

With the price of raw material skyrocketing, many manufacturers using Vibratory Separator Machines are wondering – how do we keep our costs of replacement screens at a manageable rate? According to the office of the U.S. Bureau of Labor Statistics, the stainless-steel index has increased more than 29.5% over the last year, realizing an approximate…

Production of Fiber molds (sometimes called Pulp molds) used for food and other containers has increased significantly in the last 10 years. Consumers are looking for more sustainable packaging, driving many companies to switch from plastic formed to fiber molded containers. According to the most recent report conducted by Fredonia Research for the International Fiber…

#1: Select Best Porous Media Type #2: Determine Correct Heat Treatment #3: Optimize Blank Layout Choosing the best porous media for your project is key to getting good quality, repeatable wire forms and the desired look and feel of the fiber mold. The media used will depend on size, finish, strength, and other factors required…
