Automation and Intelligence: From automatic feeding, high-temperature extrusion, and vacuum calibration to haul-off and cutting, the system achieves fully automated control, thereby minimizing manual intervention.
Specialized Screw Design: Tailored to address the high viscosity and high-filler characteristics of PP, the system employs a specialized alloy screw. While equipment from competitors often results in brittle or cracked sheets due to uneven mixing, leading production lines ensure thorough material plasticization, significantly enhancing the toughness of the finished sheets.
High-Power Vacuum Calibration Table: To overcome the challenges associated with the slow cooling and susceptibility to voids (shrinkage cavities) typical of thick sheets, the system utilizes multi-stage vacuum control and highly efficient cooling channels. Compared to competitors, the resulting formwork produced by this system exhibits no deformation in its central core areas and no collapse at the edges, with flatness deviations controlled within a tolerance of ±0.2 mm.
High-Speed Extrusion Die: Features an optimized flow channel design that ensures greater stability in melt pressure. While comparable equipment often requires reduced production speeds to maintain quality, high-end production lines are capable of stable operation at high linear speeds, typically delivering a production capacity that exceeds that of competitors by over 20%.
Three-Layer Co-extrusion Structure: Leading manufacturers are able to achieve the co-extrusion of a core layer (composed of high-filler recycled materials) and a surface layer (composed of high-strength virgin PP). This approach not only guarantees the requisite surface rigidity and hardness but also substantially reduces raw material costs.
PP building templates are widely used in the construction of residential buildings, office buildings, shopping malls, stations, plants, water conservancy, bridges, tunnels, drainage ditches, retaining walls, pipe corridors, culverts and other construction projects. When doing the installation, except for combination usage with traditional wooden profile, it can also do the combination usage with plastic profile.
The turnover times of plastic building template can reach more than 150 times, and it can be recycled. Large temperature adaptation range, strong specification adaptability. The flatness and finish of the template surface exceed the technical requirements of the existing fair faced concrete template. It has the functions of flame retardancy, corrosion resistance, water resistance and chemical corrosion resistance, and has good mechanical properties and electrical insulation properties. It can meet the requirements of various cuboid, cube, L-shaped and U-shaped building template.
Jwell started manufacturing screws and barrels in 1978, making it one of the earliest screw and barrel manufacturers in China. Its brand, "Jinhailuo", has become well recognized in the industry. In 1997, Jwell was established to begin the production of extrusion machinery. Today, Jwell is the vice president unit of the China Plastics Machinery Industry Association and one of the technology leaders in the extrusion machinery industry.
