Bidirectional Geogrid Production Extrusion Line

The bidirectional geogrid production equipment is a set of high-efficiency geotechnical material production line integrating extrusion molding, punching, heating, bidirectional stretching and automatic winding, which is specially used to produce high-strength bidirectional stretching plastic geogrid. The main processing raw materials of this equipment are polypropylene (PP) or high-density polyethylene (HDPE). The grid products produced have excellent tensile properties in both vertical and horizontal directions, and are widely used in infrastructure construction, transportation engineering, water conservancy engineering, environmental protection and other fields.

◆ Equipment Composition

Raw material supply system
Includes automatic metering feeding system, dryer, mixing device, etc., to ensure that the raw materials are evenly and stably fed into the extrusion system.
Extrusion molding system
Equipped with high-efficiency single-screw or twin-screw extruder, PP or HDPE is heated and melted, and extruded into a sheet-like blank through the die head.
Cooling and shaping system
The sheet is shaped by cooling rollers to keep it flat, providing a stable foundation for subsequent processing.
Punching device
The high-speed punching equipment punches out evenly distributed round or square holes on the sheet according to the preset program, with high control accuracy and high efficiency.
Heating system
The punched sheet enters the infrared or hot air heating furnace to reach the predetermined temperature for subsequent stretching and molding.
Longitudinal and transverse stretching unit
After longitudinal stretching, transverse stretching is performed to physically extend the material in two directions to form a high-strength grid structure.
Cooling, trimming and winding system
After stretching, the grid product is cooled and shaped, the edges are trimmed, and it is automatically rolled or cut into rolls for easy storage and transportation.
Automatic control system
The whole line adopts PLC + touch screen operation, and is equipped with temperature control, speed control, tension control, abnormal alarm and other functions to ensure efficient, stable and safe production process.

◆ FAQ

What raw materials are suitable for the bidirectional geogrid production equipment?
This equipment is mainly suitable for thermoplastic materials such as polypropylene (PP) and high-density polyethylene (HDPE). These materials have good processing properties, high tensile strength and strong corrosion resistance, and are suitable for various reinforcement projects after stretching. If the customer has special needs, the equipment can also be adjusted according to the formula to adapt to other heat-stretchable plastics.

Can the mesh specifications produced by the equipment be customized?
Yes, the equipment supports customization of mesh size. By replacing the punching die and adjusting the stretching ratio, grids of different sizes and shapes (such as 10mm×10mm to 50mm×50mm) can be produced to meet the requirements of grid strength and water permeability for different projects. We can develop molds and set technical parameters according to customer drawings or samples.

Are installation and training services included in after-sales support?
Included. We provide a full set of after-sales services, including installation guidance after equipment transportation, on-site commissioning, operator training and technical documentation support. The training content covers equipment operation, daily maintenance, troubleshooting, etc., ensuring that customers can independently operate the production line and solve common problems, thereby improving production efficiency and stability.
