The wood grain on 3D embossed wPC decking last for ever
The wood grain of 3D embossed wPC decking is processed differently from the wood grain of classic WPC decking.
The wood grain processing method of classic WPC decking is that after the wpc decking completes the extrusion production, cooling and shaping, the wood grain processing is carried out in the post-processing workshop. First, the WPC decking is surface treated, and the wpc decking is sanded with sanding equipment. Then the post-processing embossing equipment is used to heat the embossing roller, and the temperature rises to 180 degrees Celsius, allowing the wpc decking to process the texture through the embossing roller to obtain the wood grain.
The wood grain of 3D embossed wPC decking is not obtained at the post-processing embossing equipment. It is obtained directly by using a special embossing roller on the production line during the extrusion molding of wpc decking. The same online embossing roller is also To raise the temperature.
The biggest advantage of doing this is that when WPC decking is still at high temperature and not cooled, the embossing roller can emboss the surface of WPC decking to obtain wood grain with a good 3D three-dimensional effect, and finally obtain the 3D embossed wPC decking we need.
This kind of wood grain obtained online has a good three-dimensional effect. After cooling, the wood grain is fixed and exists permanently and will not disappear.
