  III. Professional Selection Guide: Scientifically Matching Application Scenarios

       In terms of material selection, HDPE is the preferred choice for long-term projects due to its excellent rigidity, weather resistance, and impact resistance. PP, although offering good stiffness, has inherent limitations in low-temperature resistance, while recycled materials are generally not recommended for critical projects due to their unstable performance and susceptibility to aging and embrittlement. The key performance requirements include exceptional weather resistance (UV resistance), adaptability to high and low temperatures, a balance of toughness and rigidity, and non-toxic, odorless environmental characteristics.

         Structure and dimensions are particularly critical, as they directly impact functionality and installation convenience. Height (15-30 cm) is directly related to isolation and soil retention capabilities: 15-20 cm is suitable for shallow-rooted plants and light isolation, while 20-30 cm or taller meets the needs of deep-rooted plants and stronger soil retention. The common length of approximately 2 meters per piece strikes a balance between minimizing seams and ensuring installation flexibility. Structurally, the classic I-beam design disperses soil pressure through side wings, ensuring stable upright placement. The anchor stakes (spikes) at the bottom facilitate insertion into hard soil and enhance resistance toppling. Additionally, sturdy and easy-to-install connectors are key to ensuring smooth, integrated lines in the isolation system.

         The ultimate criterion for selecting grass and stone isolation belts is the specific application scenario. For home gardens/villa landscapes, emphasis should be placed on aesthetics and flexibility, recommending medium-height (approximately 20 cm) HDPE products with good flexibility to create elegant curves. For public greenery/road slopes, durability and UV resistance are paramount, requiring taller (≥25 cm) and more rigid HDPE products to ensure long-term weather resistance. Riverbank protection/soil and water conservation scenarios demand the highest strength, necessitating structures with specifications ≥30 cm and bottom anchors to resist water erosion and achieve deep soil stabilization. In hard areas such as parking lots/plazas, products with extreme rigidity and conspicuous colors should be selected to withstand compression and clearly define green boundaries.

         In modern landscaping and infrastructure development, grass and stone isolation belts have become indispensable functional materials. Their neat I-beam lines and exceptional durability are backed by a highly automated precision manufacturing process. This article will take you through a typical grass and stone isolation belt production line, step by step, revealing the entire process from plastic pellets to finished products.

  IV. Precision Manufacturing Process: Technology Forging Exceptional Quality

         The creation of any high-quality product begins with rigorous preparation. Before production starts, line workers load the main raw material—high-density polyethylene (HDPE) plastic pellets—into the main hopper. To produce commonly used green products, a precise metering system proportionally blends color masterbatches with the primary material.

          Next, a crucial pre-treatment step—drying—commences. The raw materials are kept in a drying environment at 70–80°C for 2–4 hours to thoroughly remove absorbed moisture. If this step is neglected, the finalproduct may develop internal bubbles, significantly compromising its mechanical strength.

         Simultaneously, the "heart" of the entire production line—the extruder—begins preheating. The temperatures from the feeding zone to the die are precisely set between 150°C and 210°C, creating a gradually increasing thermal gradient that prepares the plastic for melting and plasticization.

Core Stages: The Transformation from Solid to Shape

Once preparations are complete, the production line enters the core phase of continuous operation.

     1. Plasticization and Extrusion

         The rotating screw within the extruder barrel propels solid plastic pellets forward. Under the combined action of frictional heat and external heating, the pellets rapidly melt into a viscous, homogeneous fluid—a process known as "plasticization." This molten plastic is then steadily pushed through a specialized forming die, extruding from the die slit as a continuous parison with the same cross-sectional profile as the grass and stone isolation belt.

     2.Vacuum Calibration: The Critical Moment of Shaping

         The newly extruded parison remains at a high temperature and in a soft state. It immediately enters the vacuum calibration table—the most critical stage determining the product’s appearance and dimensional accuracy. The calibration table is a sealed mold whose internal contour matches the final product exactly. As the parison passes through, the vacuum pump activates, instantly extracting air through micro-pores in the mold and creating a strong negative pressure around the parison. Under atmospheric pressure, the soft parison is tightly and precisely onto the cooled mold wall, instantly forming a clear, full contour.

     3. Cooling and Solidification: Locking the Permanent Shape

         The preliminarily shaped parison then enters the cooling tank. Circulating cooling water, applied through spraying or immersion, rapidly reduces its temperature from the outside in, solidifying the "I-beam" structure permanently. Sufficient cooling time is essential to prevent deformation or shrinkage during subsequent handling.

     4.Finishing and Precision Processing: Efficient Output through Automation

          1. Synchronous Pulling and Length-Based Cutting

            The fully cooled and solidified grass and stone isolation belt is gripped and steadily pulled out by a caterpillar haul-off at a constant speed. The core technology here lies in the precise synchronization of the pulling and extrusion speeds—any minor discrepancy can cause thinning or wrinkling of the product. At the end of the haul-off, the product passes through a length measurer. Once the preset length of 2 meters (or other customized lengths) is reached, a sharp cutting saw automatically activates, precisely severing the product.

          2. Collection and Inspection

             The cut finished products are automatically stacked via a conveyor belt or packaged by robotic arms. Throughout the production process, operators conduct continuous online inspections to ensure the products have a smooth surface, uniform color, precise dimensions, and are free of any defects
