In the last article, we talked about the first and second steps in the process of producing composite wood decking. Today we started the third step, starting the extrusion process and needing attention.

Composite wood decking starts to squeeze

1. Make sure that there are no impurities in the hopper or the remaining particles of other colors before, so as to avoid the color of the composite wood decking produced is not pure.
2. Check whether the vacuum equipment of the extruder is unobstructed, and ensure that the vacuum is not less than -0.08mpa. The vacuum drum should be cleaned twice per shift. Do not use metal tools to clean the vents and use plastic or wooden sticks to clean the vents of the barrel.
3. Check whether the hopper is equipped with a metal filter. The granular material is treated by metal filtration to remove the metal impurities mixed in the particles, which reduces the wear of the metal impurities on the inside of the equipment and ensures the perfect fusion of the formed plastic wood profiles.
4. Whether the cooling water system is in normal operation, the perfect cooling water system is the necessary equipment for cooling after the plastic wood is extruded, and the timely cooling treatment can ensure the good shaping of the plastic wood profiles.
5. Install the plastic wood end play, install the specified mold according to the profile that needs to be produced.
6. Check that the pneumatic cutting machine and other screw components are working properly.
7. Forming
The composite wood decking that has just been extruded has a higher temperature and needs to be manually placed on a flat surface. After the profile is completely cooled, it is processed and packaged. Even this step is simple, it is very important.

If the project ignores these details, the factory materials will often be flawed. Uneven plastic wood is likely to cause uneven thickness on the upper and lower surfaces of the product after the later grinding process. In addition, the unevenness of the profile will bring certain difficulties to the construction and affect the landscape effect.
