The honeycomb composite panel extrusion line is mainly used for extruding ABS, PE and PP panels. The resulting plastic panels are primarily used as building panels that can be reused between 80 to 100 times, with a heavy loading capacity.

The screw structure is designed according to a variety of plastic materials. In this design, plastic is heated until it's turned to a liquid, in a process known as a plasticizing method. Plastic materials undergo different plasticizing methods based on different designs and requirements, such as the venting for acrylonitrile butadiene styrene (ABS), uniform and fine foam structure, more pores for foamed polypropylene and polyethylene. Different screw designs for different plastic materials help to reduce the reaction force of bearings. Because of that, the torque on the electronic motor is generally less, allowing for a better energy saving effect.
Xiaoshan plastic sheet extrusion line uses a unique screw heater with a width of 70mm. Fine gaps between the heaters achieve a uniform heating and stable temperature control, which are both critical to the foaming process.
Temperature Control System
Our plastic sheet extrusion line also utilizes a unique copper pipe oil cooling system for screw cooling, which can precisely control the temperature in a range of ±1℃ in order to achieve an optimum plasticizing effect. Different from other systems that typically use a wind cooling process, Xiaoshan uses an oil cooling process. Wind cooling is not always effective, as the cooling process is not stable because it relies on seasonal wind temperatures, which in turn means product quality will vary. With oil cooling, however, the cooling process is stable, making this plastic extrusion line ideal for even medical grade PCL (Poly-caprolactone) low temperature thermoplastic sheet production with a temperature lower than 90℃. The oil cooling system requires only a pump requiring 0.37Kw-1.5Kws of power.
Gear box configuration
Xiaoshan uses a gear box with increased capacity. For example, for screws with a diameter of 120mm, the SJ280 gearbox works, but the SJ315 is an even better choice as it does not easily become damaged under a full load. Thus, with a full load, the SJ315 can be used for longer periods of time with less maintenance requirements to the benefit of both the customer and the supplier.
The production line uses ABS composite plastic materials which allow for an outstanding foaming effect for the plastic sheets. All extruded plastic sheets are supported using six angle type materials, which offer the sheets a better performance.
Traditional single layer solid sheets feature a heavy weight, expensive cost, restricted structure and waste material. Though the multi-layer foam sheets and hollow sheets weigh less, they also have a number of disadvantages, including a poor rigidity, poor bending capacity, and comprehensive mechanical property failings that do not meet the requirements for structure panels. It is for this reason that Xiaoshan specifically designed six angle type composite sheets with a continuous foaming method, which saves energy, lowers costs, lowers the weight, and improves the bearing capacity. Finally, these finished plastic sheets are also multi-functional.
