PLASTIC FILAMENT EXTRUDING MACHINERY

Since its establishment in 2002

Plastic safety net

A safety net is a protective net set under or on its side during the installation of high-altitude construction equipment or art performances to prevent accidents caused by people or objects falling. The safety net is composed of a net body, side ropes, tethers and tendons. The net body is knitted by net ropes, with a rhombus or square mesh. The mesh size refers to the distance between two adjacent knots of the braid. The net ropes on the edges of the net body are called side ropes. The size of the safety net (nominal size) is determined by the size of the side rope; the rope that fixes the safety net on the support is called a tether. In addition, all ropes used to increase the strength of the safety net are collectively referred to as tendons.

Construction safety nets are labor-intensive industrial products, and the production process requires several processes to complete.

1. The first is to purchase raw materials, the choice is virgin plastic pellets high-density polyethylene (HDPE or PET), the finished product is mainly a special dense mesh net for testing, and the recycled material is generally mineral water bottle cap material, and then use The machine is crushed and granulated.

2. Next is filament drawing or fiber making by plastic safety net filament extruding machine line. This process is very important. The production process requires precise control of the cooling water temperature. The thickness, color and flexibility of the plastic filament produced determine the quality of the finished product. Next is the net weaving. The dense mesh looms usually used are 2 meters and 4 meters wide. In this production process, the weaving process also determines the quality of the finished product. Mainly to control the weaving structure and weaving density of the dense mesh net, usually mesh density: ≥800 mesh/100cm² above.

3. Next is stitch sewing. First cut the woven tubular mesh fabric, usually measuring 6.2m to 6.5m, so that the length of it can be about 6m after sewing. When sewing, wrap the rope close to the edge of the mesh and then drive it together. The weight of the rope is compatible with the mesh, and should not be light or too heavy. Sew around the edge of the mesh twice to ensure that it is secure and put the product certificate in.

4. After the sewing is completed, it is a metal ring, which is used to tie the rope through when hanging the dense mesh net. Usually more than 20 to 30 holes are punched. Machines are now widely used. The last step is to fold the dense mesh net, pack it, and leave it for sale.
