Unidirectional Geogrid Production Line

Unidirectional geogrid production equipment is an efficient and automated production line specially used for manufacturing unidirectional tensile plastic geogrids. Its main function is to produce unidirectional grid products with excellent longitudinal tensile strength by extruding, punching, heating, unidirectional stretching and other processes on thermoplastics such as polypropylene (PP) or high-density polyethylene (HDPE).
Unidirectional geogrids are widely used in engineering fields such as roads, railways, dams, retaining walls, slope reinforcement, etc., playing a role in strengthening soil structure, dispersing stress and improving stability. With the continuous advancement of infrastructure construction and the expanding geotechnical material market, the unidirectional geogrid production line with efficient, stable and automated production capacity has become one of the core equipment of many geotechnical material manufacturing companies.
This equipment has the advantages of reasonable structure, simple operation, high output, low energy consumption, and convenient maintenance. It is suitable for large-scale continuous production and can meet the diverse needs of geogrids for various engineering applications.

◆ Equipment Composition

Raw material feeding system
Use automatic feeding and mixing equipment to accurately feed PP or HDPE granular raw materials to the extruder. According to production requirements, antioxidants, stabilizers or masterbatches can be added to improve the performance and appearance of the finished grid.
Plastic extrusion system
The high-efficiency single-screw or twin-screw extruder heats, melts, and plasticizes the raw materials, and evenly extrude them into plastic sheets with uniform thickness through the die head, providing basic materials for subsequent processing.
Cooling and shaping device
The extruded plastic sheet is quickly cooled and shaped by the cooling roller to keep the sheet flat and smooth and stable in size, creating good conditions for subsequent punching and stretching.
Punching device
Use high-precision punching equipment to punch holes on the surface of the sheet according to the set pattern. The hole shape can be round, square, diamond, etc., evenly distributed, with high hole diameter and arrangement accuracy. This process directly affects the mechanical properties of the grid structure.
Preheating and stretching system
The punched sheet is preheated by a heating furnace. After reaching the required stretching temperature, it enters the unidirectional stretching system and performs precisely controlled mechanical stretching in the longitudinal direction, so that the material forms a strong oriented molecular chain in one direction, thereby significantly improving the tensile strength in that direction.
Cooling, shaping and traction system
The stretched grid quickly enters the cooling section for shaping, and its shape and size are maintained by the tension control system to ensure the stability and consistency of the product.
Reeling and cutting unit
After cooling, the product can be automatically rolled into a roll for subsequent packaging and transportation; it can also be cut into sheet products of specified size according to customer requirements.
Electronic control system
The entire line adopts PLC control system and human-machine interface operation, automatically adjusts process parameters such as temperature, speed, tension, etc., has fault alarm, remote control and data recording functions, and realizes highly intelligent production management.
