Extruded Diamond & Square Mesh
Plastic Diamond Mesh Netting
Plastic diamond mesh netting is produced using counter-rotating dies creating strands in opposite directions overlaying each other. This joint structure is quite different from the structure of Square Mesh Extruded Plastic Netting. The overall thickness of extruded plastic diamond netting will essentially be twice the thickness of each strand, although there will typically be some melding of the strands at the joint.
Normally, the strands in each direction are produced uniformly, and the product looks the same from one side of the material as the other. This type of netting is marketed as "bi-planar", where both sides are structurally the same and the strands are forming a plane or channel along the net. Diamond netting results from two strands overlaying each other, typically at a 90-degree angle but ranging from 40 degrees to 105 degrees, to create a diamond hole pattern. Diamond netting is the most common type of extruded plastic netting.
Diamond Mesh Netting will stretch under tension causing the hole shape to elongate in one direction and narrow in the other. This "accordion affect" causes the tensioned dimension to shorten and the perpendicular dimension to grow as material relaxes. Tolerances only apply at time of cutting.
Plastic Square Mesh Netting
The joint structure of Plastic Square netting is produced using reciprocating dies. Machine direction strands run the length of the roll and cross direction strands run the width of the roll. Joints are formed at the intersection and are not stacked one over the other as in diamond net mesh plastic netting. Square netting results from strands being formed along the x and y plane, creating a square or rectangular hole pattern.
Generally, the machine direction strand is thicker than the cross direction strand. The overall thickness of the netting is typically determined by the machine direction strand thickness. As a result of this joint configuration, plastic square netting usually has one side of the material that is smooth, that is, both the machine and cross strands are flush on the same plane, and one side that is "bumpy", where the machine direction strand has a higher profile than the cross strands.
Square mesh plastic netting is extruded in a wide range of configurations featuring:
- Structural integrity
- Apertures "locked" by fused joints
- Smooth surface on one side
All extruded plastic netting is extruded in tubular form. It is most common for the tubular netting to be slit open longitudinally during the process to create a flat roll of material. In some cases, however, the netting is kept in its tubular form. The oriented produce bags for packaging referenced earlier is one such example. Another example in the filtration industry is rigid plastic (netting) tubes for center cores or outer sleeves (cartridge filtration). Tubular structures are also produced to be flexible or stretchy, as is often seen on the outside of cartridge filters. There are other applications as well for rigid and flexible tubular plastic nets. The range of products and markets for plastic netting are quite diverse. To see all of the products and uses, one might think many processes were used to produce such products. But, in fact, the extrusion and orientation processes are capable of producing an ever-widening array of products for the filtration industry and other markets.
Most products from Industrial Netting are available in bulk rolls or custom cut sizes. Utilize Industrial Nettings' Custom Converting Services to receive the specific sized netting for your needs. Some of these services include slitting, sheeting, or die cutting. Choose from a broad range of hole apertures, thicknesses, and material resins - or contact us to help identify a specific product for your intended application.
Tolerances vary with apertures (hole sizes), weights, thicknesses, and roll widths
