Extruded plastic netting is created in a continuous process in which plastic resin pellets are melted and pushed through a die in "meat-grinder" fashion to form a continuous mesh. Two important elements of this process are that it is continuous, and the product is produced in its final form as a plastic net or plastic mesh netting roll. Extruded (or cast) netting can be produced in configurations ranging from fine filtration-grade plastic netting (resembling woven fabric) to a more coarse extrusion, typical of plastic construction fencing. If you are looking for quality plastic mesh suppliers, Industrial Netting has you covered!

Diamond Mesh Plastic Netting is extruded using counter-rotating dies. Joints are formed when two strands intersect or overlay each other forming a diamond pattern. Two distinct planes (known as flow channels in some applications) are created when the opposing strands overlap. The overall thickness of the product is essentially twice the thickness of each strand.

Square Mesh Plastic Netting is extruded using a circular oscillating die plate. Longitudinal strands are determined by the size of the holes around the circumference of the die plate. Cross strands are created when the die plate opens, creating an integral joint structure along the x and y plane. Cross strand thickness and spacing can be controlled in process to create square or rectangular apertures. Square mesh Plastic netting typically has one flat side created by the hot extruded mesh tube passing over a mandrel.

Oriented Plastic Netting is produced in a secondary operation by heating and stretching extruded square mesh netting to create a lighter-weight material with higher strength to weight ratios. Bi-axial orientation typically "stretches" the original extrusion by 3 to 4 times the original width and length.

Diamond plastic mesh and square plastic mesh are both extruded in tubular forms and then slit longitudinally in process to create flat rolled material. Tubular Plastic Mesh Sleeves are extruded using the same diamond mesh extrusion process but left unslit in tubular form.

Expanded Plastic Mesh is produced by slitting plastic sheet stock in a controlled pattern, then stretching or expanding the width to produce the designated nominal aperture (hole) size. Dimensional measurements for expanded mesh are somewhat different than extruded and oriented mesh (see diagram to right).

Woven Plastic Mesh Fabrics are produced by weaving monofilament fibers using advanced looms and finishing equipment. The mesh opening for a given strand thickness is dictated by controlling the threads per inch (weft mesh count and warp mesh count).

Metal Mesh Screens, Filters, & Sieves

Industrial Netting offers a wide variety of metal mesh products manufactured using distinctly different processes to produce various performance advantages for virtually any application.

Electroformed Screens: Suitable for many applications where precision and versatility are at a premium. Available in a number of configurations in nickel, copper or gold. The unique attributes of each element, coupled with universal consistency and tight tolerances, are ideal for uses in light, air, sound or matter filtration.

Micro-Mesh® Electroformed Sieves: Precise opening with tight tolerances for particle analysis, measurement and separation. Durable nickel sieves are long lasting with both Standard and Ultra tolerances suitable for most any precision-sensitive area or application. The flat, smooth surface that simplifies cleaning and minimizes particulate entrapment is particularly favored in power industry applications.

Chemically Etched Screens: Manufactured via photo etching / photo chemical milling, these burr-free stainless steel screens feature precise control of hole placement and size tolerance, as well as greater dimensional stability than conventional woven wire mesh. This makes etched screens ideal for applications with high cleaning frequency or mechanical contact.

Precision Etched Pin Holes: Are used in a wide variety of applications including leak detection / testing, calibration and research.
