extrusion. Otherwise, it will soon be eliminated by the market. Some manufacturers are worried about co-extruded wood will increase product costs, in fact,pvc wood planks supplier in philippines the direct cost of co-extruded wood plastic production will not increase, although the surface co-extruded layer of high cost, but the cost of the core layer (back material, Less additives, more wood flour). Co-extruded surface layer thickness is very thin (0.3 ~ 0.5mm, to emboss only 1mm), you can not usually use the good additives (UV, antibacterial, masterbatch, lubrication, etc.) are added to the color system can a bit more. If I visited the world's second largest WPC plant, the original only 4 kinds of colors, co-extruded WPC flooring out of 8 colors, as long as the co-extrusion extruder hopper plus side feeder can be easily achieved. The direct cost of production did not increase,composite outdoor furniture kits but the initial need to invest in molds and co-extrusion special extruder. u0026lt; BR u0026gt; using a special extruder or screw stable quality. I saw several domestic WPC plant trial WPC co-extrusion products, found that the quality is not stable enough, uneven thickness, the skin is easy to fall off, the surface quality is lacking (internationally popular is Matt (Low-Gloss)), in addition to raw materials Of course, new materials, fine wood flour),japan composite decking board additives and molds, the main reason is that the extruder, be sure to use a special extruder for WPC, at least with wood-plastic co-extrusion special screw. Commonly used for extrusion molding wood-plastic extruder TC35 or TC55 conical twin-screw extruder, high back pressure, small shear, plastic mixing well. In addition, compared with ordinary wood-plastic extruder, due to the thin co-extruded layer, wood-plastic co-extrusion extruder for higher process
