Plastic 3D Drainage Net Machine

Taking HDPE as raw material, the ribs of drainage net are extruded from special die head. Every three ribs form 3D structure with drainage channel through fixed gap and angle. The rigidity of the middle rib is high, which shapes rectangular drainage channel. The three ribs have great tensile strength and compressive strength. The drainage channel among the ribs can afford high load. It can prevent the geo-textile from imbedding the net core and ensure the channel expedites. Drainage net can be divided into two types: high strength and high channelization.
