Wood plastic composite decking production notes

Wood plastic in the production process also requires a series of processes, and not really just like squeezing out that rice cake on the line.

Plastic profile in the extrusion die, should be immediately cooling treatment, to prevent the emergence of deformation profiles because under the gravity, depression or distorted phenomenon. If it is shaped hollow sections, also need to be equipped with vacuum forming device, to ensure the products structure size accurate. Generally speaking it the setting and cooling is needed at the same time, extrusion sheet and sheet, sometimes by a pair of rollers to squeeze out.

If it is for the high content of ecological wood or wood products is thinner, can be used for cooling, wood fiber content is less, or the thickness of a relatively large ecological wood products, it is best to use cold water. Extrusion is stacked smooth, prevent bending, if not put level, because after the extrusion length long, gravity and just extrusion temperature high is prone to dent in the middle, on both sides of the tilt.
