Plastic Sheet Extrusion Line (Anti Slip PE, PP, PC Sheet Production)

Our plastic sheet extrusion line is designed to extrude anti-slip PE, PP and PC sheets. It can produce hard sheets with a thickness between 0.25mm to 2mm using 100% HDPE or recycled LDPE raw materials. The final sheets are used in a variety of applications, including building waterproof sheets, door and window waterproof sheets, plant root preservation sheets or as pad boards and more.

Screw structure design

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 the main motor of the three-layer co-extrusion blown film machine, with the main screw's diameter being 180mm, and the auxiliary screw's diameter of 90mm.

Heating system
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.

Gearbox configurationg
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.

Sales case
We sold two extrusion lines to an Australian customer:
The first plastic sheet extrusion line
The second plastic sheet extrusion line
The second one is a PE three-layer co-extrusion line. Three rollers are positioned at mid or high heights, allowing for a highly precise control of sheet thickness. A hard chrome plating and mirror finish polishing give the extrusion line its smooth, fine surface.
