Hexagonal wire net is also known as hexagonal wire mesh, chicken wire mesh, or poultry nets. It is the net that has the hexagonal pattern instead of the typical square or diamond gaps. This type of net can be made from a wide range of materials based on the end application; it can be made from iron for industrial applications or it can be made from petroleum-based materials for general-purpose applications.
Made from galvanized iron or plastic coated stainless steel, the hexagonal wire mesh has excellent corrosion resistance and oxidation resistance which make the nettings suitable for strengthening, wrapping and protection applications. Conventionally, a net is woven manually by fabricators; to date, this type of netting is made by a hexagonal wire netting machine.
A hexagonal wire netting machine is an automatic machine used to make hexagonal mesh for a wide range of applications such as for fences of farmland and grazing land, chicken husbandry, reinforced ribs of building walls, wrapping cargos and more. The hexagonal wire netting machines are also called chicken cage machines, or double twisted hexagonal mesh machines. Human factor is minimized during the netting process since the machine is highly automated and self-contained. The operator is only involved in works such as machine value settings and maintenance.
Generally speaking, a hexagonal wire netting machine applies the forward and reverse twisting weaving technology to produce hexagonal mesh; it is called a double twisted hexagonal mesh machine as a result. The term mesh refers to the hexagonal gaps in the net; the size of the mesh is determined by the specifications of the machine. The forward and reverse twisting weaving technology allows the machine to work continuously without making the wire into a spring shape. The wires will be rolled and woven by a winding shaft which turns the wires into a hexagonal mesh net.
The overall length of a hexagonal wire netting machine is important because it determines the number of rolls that the machine can manufacture in a weaving cycle. The longer the machine is, the more rolls of net the machine can weave at the same time. For example, a 5-meter long machine can manufacture two 2-meter rolls and one 1-meter roll in a cycle while a 4-meter machine can only weave two 2-meter rolls in a cycle.
The wires that are used to produce the hexagonal mesh are usually stainless steel wires. The other common hexagonal wire mesh materials are low carbon steel wires. A hexagonal wire netting machine is usually capable of producing at least 60 meshes per minute with the stainless steel wires. That being said, the operating speed can be adjusted according to the conditions of the steel wires. Sometimes it speeds down in order to reduce the risk of wire breakage. Though stainless steel has high tensile strength, it is still possible that the wires break apart if the materials are processed at an improper speed.
The speed control of the netting machine is crucial not only to prevent the breakage of the materials but also to assure the tidy and flat finish of the net. The speed control of the machine is achieved with the implementation of an electronic netting tension sensor unit. Once the tension value is set, the machine can automatically adjust the winding speed so that the roll ends are perfectly wound up. The tidiness of the net not only offers a desirable presentation of the product but also makes the net easier to be stacked and stored.
The width of the hexagonal mesh net ranges from 1 meter to more than 2 meters according to the end application of the net. Some hexagonal mesh machines are able to weave a mesh net wider than 2 meters. The braking system on the machine controls the startup and stop of the machine. Once the predetermined length of the net is reached, the machine automatically stops and the roll is removed from the winding shaft. When a cycle is completed, the machine starts up again to weave the next net.
