Metal Filter Screen

Filter screens are open yet protective barriers that are simple in design, but very effective in removing dirt, dust and other particles from any liquid. These screens take the idea of strainers or window screens and apply it to filtration systems of all kinds. The food and beverage manufacturing, petro-chemical, agricultural, water purifying, mining, pharmaceutical and oil industries use filter screens to purify and clean many different types of liquids, including irrigation water, potable water, oil, alcoholic beverages and juices.

One of the most common places to find a filter screen is in faucets. They are small, round pieces of woven wire mesh situated at the faucet opening to catch any debris and dirt that made it through the drinking water system. Filter screens are reusable, long lasting, and very resistant to a variety of temperatures and moisture. They won't rust, unravel or wear out easily. If that does happen, filter screens are very inexpensive and easy to replace

Wire mesh is fabricated by the intertwining, weaving, or welding of wires of various thicknesses to create proportionally equal parallel rows and intersecting columns. Also known as wire fabric, wire cloth, or hardware mesh, the production of wire mesh involves the weaving of wire on industrial looms, leaving square or rectangular gaps between the wires. Welded wire mesh or fabric is manufactured using an electric welder that joins parallel longitudinal wires where the wires intersect.

The processes used to produce wire mesh are weaving and welding, with wire weaving being similar to the weaving of cloth on a loom, while welding is used to join the wires where they intersect. Both processes are completed using pre-programmed machines.

There are a limitless number of shapes, sizes, and configurations of wire mesh made from an assortment of highly durable and resilient materials whose major function is to separate, screen, structure, and shield various applications and processes. The types of wire include galvanized steel, stainless steel, aluminum, steel, and copper alloy wire. The type of application, necessary tensile strength, durability, longevity, and required flexibility are some of the factors used to determine the desired type and style of wire.

Wire Weaving

· Weaving Loom — Weaving looms weave mesh rolls with widths of 48”, 60”, 72”, 98”, or wider. The loom has a warp beam, heddle frames, a reed, a rapier for transporting weft wire, and a take-up mechanism.

·Manufacturers use looms to weave meshes of standard and custom patterns. The completed mesh rolls are cut to varying lengths depending on the needs of customer specifications. Wires woven horizontally or lengthwise are warp wires, while wires woven vertically or crosswise are referred to as weft wires or shute wires, terms commonly used in textile manufacturing.

·Warp Beam — The warp beam is a cylindrical drum wrapped with the warp wires. The warp beam's tension must be meticulously controlled to avoid elongation of the woven mesh. The number of warp wires varies depending on the mesh width and must be kept the same length.

·Heddle Frames — The heddle frames separate the wires that are fed by the warp beam. Most looms have two heddle frames, with one used to lift half of the warp wires while the other pulls the warp wires down. The heddle frames change position as the weft wires move across the warp wires.

·Rapier Band — The weft wires are carried across the full width of the cloth by the rapier at each cycle of the heddle frame. It feeds a single weft wire between the sets of warp wires.

·Reed — The reed keeps the warp wires from the warp beam in place and accurately spaced and separated. Once the weft wire moves across the warp wires, the reed beats the weft wires tightly in place in the wire cloth.

·Take-Up — The take-up mechanism is a set of rollers that takes the fabric away from the loom with a pickup roller and two other rollers that work together to wind the cloth to the cloth roller. The fabric is wound in single layers with a smooth flat surface created by it being passed through the set of rollers.
