Wood Plastic Composite Manufacturing

木塑生产过程

Extrusion line is a major set of equipment intended for extruding of WPC linear profile.

挤出生产线是挤出木塑型材的一组主要设备。

The primary unit of extrusion line is extruder machine. Auxilaries (downstream) include modules located after extrusion die: cooling section, hauling-off (puller) unit, cutter, overturning table.

该挤出线的主机组成部分是挤出机,辅机(下游设备)包括挤出模具、冷却部分、牵引机,切割机及翻转台。

Extruder

木塑生产流程 - eric.lee - 环保木塑家具

To achieve required extrudate the palletized compound is fed into extruder through gravity filling bunker. It is heated and melted to uniform flow mass inside the cylinder of the extruder.

通过真空送料装置将料送入料筒,在挤出机螺筒内原料开始被加热和熔化做一定标准的流体状。

Extrusion Process

Then melt flow is transferred and pressed through the slit of the die. This is done by a screw rotation inside the extruder cylinder generated by v-motor.

流体状的原料经模具挤压成型,通过控制螺杆的转速来调节其挤出速度。

Cooling section

Uniform cooling around/along the outlet of extrusion die is considered to be very important factor of the extrusion process. Cooling equipment comprises water tank furnished with auxiliary sizing facilities. Extruded blank is pulled by the tractor through the water and cooled. While passing under water along the cooling tank the extruded profile is subjected to shrinkage due to temperature drop. However the size of the product depends not only upon cooling but also upon the speed of traction.

冷却部分对产品的成型非常的重要,其主要是由水箱及辅助定径装置组成,产品在水槽里随着温度的降低而收缩,但是产品的定径不仅仅取决于冷却装置,牵引装置同样的重要。

Tractor (puller)

Tractor (puller) is a caterpiller-type machine, that pulls the extruded blank through water tank, pushing it further on downstream to cutter and handling table. The tractor pulls the extruded profile with uniform speed, without allowing it to slip. This process is closely related to final dimensions of the finished product.

双履带牵引机将制品从冷却水槽牵引至切割机和翻转台,其速度是标准一定的,不允许有滑脱现象,该过程与制品的最终成型有着紧密的联系。

Cutter

Cutter is a device that fixes the extruded profile and cut it to desired length by means of thermal knife.

通过切割机将制品固定并切割成一定得长度。

Overturning table

To cut the profile to desired length the blank is placed along the handling table, following the cutter. Cut piece is overturned to finished profile collector.

通过调节翻转台的感应器,控制制品的长度,并翻转堆叠到台下。

Advantages of our WPC products:

Low maintenance

No moisture absorption

Won’t warp or crack

Resists fungus & mold

Resists termites & insects

Thermally stable than plastics

Dimensional stable than wood

In short, WPC is durable, maintenance-free, eco-friendly and therefore an excellent alternative to tropical hardwood.
