The screw structure is designed according to different 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.
This is a single-layer extrusion line, with main screw diameter of 135mm.
Xiaoshan's plastic sheet extrusion line utilizes 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 for 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.
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.
PE plastic sheet extrusion lines were sold to a customer in Guangzhou, Guangdong Province, China. The customer bought two poultry manure belts, allowing for a precise control of sheet thickness. Hard chrome plating and mirror finish polishing are all used on these machines, ensuring the sheets have a fine, smooth surface. The customer was extremely satisfied with our equipment, and is in discussions to buy more from us
