In the field of PVC wood-plastic foam board production, stable production has always been a major challenge faced by the industry. The raw material characteristics vary greatly, the equipment parameters are difficult to accurately control, and the process links are complex and changeable. Problems in any link will lead to fluctuations in product quality, such as uneven board thickness, poor foaming effect, surface defects, etc., which not only affect production efficiency, but also cause waste of raw materials and increase corporate costs. However, the PVC wood-plastic foam board production line launched by Sure Plastic Machinery has successfully solved these production problems with its excellent performance and brought a new solution to the industry.
In the plasticization stage, the production of PVC wood-plastic foam boards has extremely high requirements for material plasticization, and ordinary equipment is difficult to meet the complex plasticization requirements of PVC and wood powder in the raw materials. Sure Plastic Machinery's production line is equipped with a carefully designed gradual-change screw, the compression ratio can be flexibly adjusted, and with a suitable drive system, at an output of 50-100 kg per hour, the drive power of 15-30 kilowatts can ensure that the material is fully plasticized, solving the product quality problems caused by poor plasticization from the root.
Extrusion stability is the key to ensuring the stable production of PVC wood-plastic foamed boards. Fluctuations in flow and pressure will directly affect the thickness and foaming uniformity of the board. Sure Plastic Machinery strictly controls the extrusion flow fluctuation within ±1% and the screw speed fluctuation within ±0.5% through a loss-in-weight metering feeder and a high-precision frequency converter. With the help of a pressure sensor and a feedback control system, the extrusion pressure fluctuation is stabilized within ±0.5MPa, making the board thickness uniform and the foaming consistent, effectively avoiding the increase in the defective rate caused by unstable extrusion. Temperature control accuracy is crucial to the production of PVC wood-plastic foamed boards. Too high or too low temperature will cause a series of problems. The heating system of Sure Plastic Machinery production line adopts ceramic or cast aluminum heating coils, with a temperature control accuracy of ±1℃. It is equipped with a precisely controlled circulating water cooling system, with a cooling water flow rate stable at 2-3 m/s and a water temperature controlled at 15-25℃, to achieve precise control of material temperature, ensure stable material performance during production, and avoid product defects caused by temperature problems.
Mold accuracy is directly related to the appearance and performance of the product. The shortcomings of traditional molds in processing accuracy and flow channel design can easily cause uneven material flow. The mold cavity size accuracy of Sure Plastic Machinery is controlled within ±0.05 mm, and the surface roughness reaches Ra0.8-1.6 microns. The streamlined flow channel design combined with the spoiler device helps the material flow evenly and the foaming agent disperses, ensuring the beautiful appearance and excellent performance of the board. In addition, the high-precision operation of the traction machine and the cutting machine ensures that the synchronization error of the traction speed and the extrusion speed is within ±0.5%, and the cutting size error is controlled within ±1 mm, further improving product quality.In addition to the excellent performance of the equipment itself, Sure Plastic Machinery also provides all-round guarantee for the stable operation of the production line from multiple dimensions such as equipment selection, installation and commissioning, maintenance and automation control. Strictly select and optimize equipment configuration, professional and standardized installation and commissioning process, perfect maintenance system and advanced automation control system to achieve comprehensive monitoring, precise control and data intelligent analysis of the production process, and ensure long-term stable and efficient operation of the production line.
Sure Plastic Machinery PVC wood plastic foam board production line has successfully overcome the difficulties of stable production of PVC wood plastic foam board with its powerful performance and perfect guarantee system, bringing stable and efficient production experience to enterprises, greatly improving product quality and production efficiency, and reducing production costs and energy consumption. In the future, Sure Plastic Machinery will continue to innovate, inject more power into the development of green building materials industry, and lead the industry forward.
