Sintered Mesh- Excellent filtration for high pressure applications



The characteristics of woven wire mesh are improved by bonding the contact points of all the wires together to form a mesh whose wires are securely fused in place and this process is known as Sintering. This is obtained using a combination of heat and pressure and the result is a single layer Sintered Wire Mesh. 5-Layer Sintered Wire Mesh is one of the most common types of Sintered Wire Mesh laminates and it is widely used. A single layer of fine woven wire mesh is placed between two layers of coarser square woven meshes and then added to two layers of a strong Dutch woven wire mesh and sintered together to form a  strong plate. 

The single layer of fine woven wire mesh acts as the filtration layer and can be customized to meet a particular filtration rating ranging from 1 micron to 200 microns. These layers consist of 316L stainless steel wire mesh. Other alloys can also be used including Inconel, Hastelloy and Monel. Standard size is a 2’x4′ or 4’x4′ sheet and various size tubes, cones, discs and larger sheets can be fabricated. This Sintered Wire Mesh laminate is used in numerous industries including food & beverage, pharmaceuticals, transportation and chemical processing. Various applications of this Sintered Wire Mesh laminate include pharmaceutical powder processing, fluidized beds, liquid and gas filtration.

PerforatedMetal Sintered Wire Mesh is a laminate made by taking several layers of woven wire mesh and sintering them to a layer of perforated metal. The woven wire mesh layers consist of a filter layer, a protective layer and possibly a buffer layer between the fine mesh layer and the perforated plate. The perforated plate is then added as the base and sintering is performed on the entire structure to form a strong and tractable plate. This Sintered Wire Mesh laminate has high resistance to pressure and has high mechanical strength due to the support of the perforated plate. It is ideal for various applications that require filtration and also require the protection and preservation of the filtration layer. One such application is oil wells where fine particles need to be filtered under extremely high pressure conditions. Various alloys can be used including the 316L stainless steel wire mesh which is commonly used for the woven wire mesh layers and the 304 stainless steel which is commonly used for the perforated plate. 

The customization of the woven wire mesh layers can be done to meet the filtration rating and the customization of the thickness of the perforated plate and type of perforations can also be done. Standard size is 2’x4′, or 4’x4′ and various size discs and sheets can be manufactured. This Sintered Mesh Laminate is commonly used in tube form. The customization of these sintered filter tubes is done in a variety of diameters and lengths.

Another type of Sintered Wire Mesh laminate is Plain Weave Sintered Square Woven Wire Mesh that is manufactured by sintering multiple layers of plain weave square woven wire mesh together. This Sintered Wire Mesh laminate has excellent permeability characteristics and low resistance to flow due to the large open area percentages of the square woven wire mesh layers.

Tungsten Mesh- Ideal material for electrodes



Uniformshaped Tungsten Meshes are used as screen or gauze. These are produced in standard metal mesh size range from 0.75mm to 1mm to 2mm diameter with strict tolerances and alpha values (conductive resistance) for uses such as gas detection and thermometry tolerances. Materials are produced using solid state, crystallization and other ultra high purification processes such as sublimation. Custom compositions are also produced for commercial and research applications and for new proprietary technologies.

Tungsten metal has a lustrous and silvery white color and doesn’t occur naturally. It is found in the ore Wolframite which is a tungstate of iron and manganese. It is converted to the trioxide and then reduced to the metal by reduction in hydrogen. Tungsten metal is relatively inert and has resistance to acids and alkalis. It has resistance to attack by oxygen although it reacts with fused oxidizing alkali media. It has high melting point and can be worked with relative ease when pure. Tungsten can be extremely brittle due to the presence of impurities and becomes difficult to fabricate. Tungsten is ideal for use as electric filaments due to its high melting point. Tungsten and its alloys are used in military applications for example, shells and armour, as well as counter-balance materials. Tungsten carbide powder with possible additions of titanium and tantalum carbides along with nickel or cobalt powders are compressed and sintered to produce cemented carbides. These cemented carbides are used to form the tip of cutting and drilling tools or for parts which will be subjected to heavy usage.

Tungsten is used in electrodes, electronic applications, medical devices and vacuum heating elements due to its high melting point and tensile strength at extreme temperatures. Tungsten and Molybdenum elements are produced in both mesh and weave configurations. The mesh and weave heating elements are made from continuous interlocked tungsten or molybdenum wire coils. Each wire moves independently when heated. Interlocked wire coils mean that each element has built-in flexibility. This largely eliminates mechanical and thermal stresses leading to improvement in the life of the element. These elements are manufactured in cylindrical and flat panel designs. Mesh elements consist of individual helix coils of tungsten or molybdenum wire that are threaded together by turning each coil into the adjacent coil making a continuous interlocking mesh pattern over the entire width and length of the element resulting in unmatched thermal performance. Consistency is maintained throughout the construction of each element since the wire diameter for each coil is closely controlled. Conductors are made of the top and bottom ends which are secured with solid strips of tungsten or molybdenum bands. These conductors provide a means of mechanical support for the element. The welding of these bands and tabs is performed under a controlled atmosphere to minimize stresses within the elements.

Individual wires are formed into planar sinuous loops to produce weave elements. The wire diameter, height and pitch of the bends are controlled as required to produce the optimum weave element design. A hair-pin wire is connected together with the individual wires passing through alternating loops similar to a cloth fabric weave to securely lock the wires together. The individual wires are free to move and adapt to the thermal environment. The weave is an alternative to the mesh construction technique. The ends are terminated in the same way as the mesh elements.

Leaf springs and coil springs are widely used in the motor vehicle industry. Premature fatigue failure is common and the reasons for these failures are complex such as heat treatment, intergranular cracking, grain boundary embrittlement, design deficiencies, steel alloy chemistry and presence of Fe-S inclusions. This study provides an overview of spring steel including its heat treatment, fatigue failure, chemistry, residual stress and failure analysis of leaf and coil springs.

A spring is a component that can store energy temporarily and permanently. There is a need of improving fatigue strength of spring materials due to cyclic loading that accompanies the use of springs. Spring efficiency is related to its ability to store energy per unit weight and steel strengths of greater than 1379 MPa are required. Spring steels were developed to meet ever-increasing demands for improved mechanical properties with lower weight suspension materials to facilitate the larger effort of developing automotive vehicles with lower weights and lower cost. High strength spring steels with improved sag strength, fatigue strength and improved quench embrittlement properties in addition to other thermophysical and mechanical properties were developed in this work. 

The two types of springs were discussed such as helical coil springs and leaf springs. Coil springs are commonly used in the automotive industry and are constructed from a length of round steel wire that is formed into loops which allow for movement. Coil springs are classified as compression and extension springs. The objective of this study was to provide an overview of the most important factors involved in either coil spring or leaf spring failures. As per the conclusion of this study, surface defects including decarburization but the presence of seams, laps and other defects lead to premature spring failure. High quality outer layer of spring wire is achieved by a grinding or a draw-peeling process to address these problems. Emphasis on spring design innovations is increased which can be used with higher loads at reduced spring weight and size with substantial improvements in fatigue strength.
