HDPE Plastic Road Barrier Specialized Blow Molding Machine
Road Blow Molding Machine is a dedicated blow molding equipment engineered for manufacturing hollow plastic components applied in highway engineering projects.
By means of parison extrusion and high-pressure air inflation processes, it achieves one-step molding of a diverse range of road facility fittings. Its key advantages include superior molding accuracy, strict adherence to industrial product strength criteria,
and production efficiency that aligns with engineering construction timelines. The machine directly caters to the standardization and mass production demands of road construction, replacing conventional techniques like injection molding and manual assembly,
and greatly enhancing the manufacturing quality and construction efficiency of highway infrastructure accessories.
1. Integrated Hollow Molding Function: Enables direct production of seamless hollow road products with no need for splicing, which effectively guarantees the structural wholeness and airtight performance of the finished products.
2. Precise Dimension Control Function: Adopting servo drive, intelligent mold positioning and closed-loop control over extrusion speed, the device controls the dimensional tolerance of products (including diameter, wall thickness, height and other
parameters) within ±0.5mm, fully meeting the standardization specifications of road engineering construction.
3. Automatic Feeding and Molding Linkage Function: Connectable with automatic feeders and dryers to achieve automated conveying and drying of raw materials; the double-station/multi-station structural design supports the synchronous operation of molding,
product demoulding and edge trimming, enhancing the continuity of the production process.
4. Intelligent Temperature Control and Cooling Function: The sectional screw temperature control system ensures the homogeneous melting of raw materials; the intelligent mold cooling system can automatically regulate cooling duration and water flow according to
product dimensions and raw material types, shortening the molding cycle and boosting the qualified product rate.
5. Fault Self-Diagnosis and Alarm Function: The equipment conducts real-time monitoring of operational parameters including motor current, extrusion pressure and mold temperature. In the event of an abnormal condition, it will trigger an automatic alarm and
display the fault location, enabling rapid troubleshooting and maintenance.
6. Customized Molding Function: Interchangeable molds allow for the production of road products in various specifications and shapes; large-sized machine models support the customized
manufacturing of special-shaped and non-standard road facility products.
1.Energy and Material Saving: Saves 25%-35% raw materials compared to roto-molded tanks; servo hydraulic system saves over 40% energy, and extruder upgrade saves an additional 10% energy.
2.High Efficiency: Higher output than roto-molding machines, with 7-9 pieces per hour for 2000L specification.
3.Outstanding Quality: Strong impact resistance, flawless product quality, and multiple international certifications.
4.Easy Operation and Maintenance: Only 2 people are needed to operate the main machine, and 3-4 people for the entire production line; modular core components for convenient maintenance.
