3. Introduction wpc production of raw materials
wpc available raw materials used in plastics and waste wood waste,
forestry, straw and other plant fiber as the base material does not
contain any harmful ingredients plus, and recyclable, after processing
factories, producing wood products made of special plastic and wood
flour very green; using coupling agents as surface modifying agents to
improve the compatibility of the inorganic filler, inorganic fiber and the
matrix resin is, but also can improve the interface between the polymer
and the condition of the wood meal.

7. Granulation process
• The raw material to be blender stir the raw material input granulator,
granulating machine high temperature heating, dehydration, cooling and
a series of processes, the raw materials processed into wood particles,
which is the wood products manufacturing direct materials .

8. Extrusion process
• The particles made good input extruder heated to high temperatures,
it becomes cozy state, through wood abrasive extrusion.
(Material by shearing action of the screw and the outer heat in the extruder, the
average of the plasticizing extruder head into the abrasive, the material is given
a certain shape in abrasive in a row and further away from the plasticizing
extruder)

10. Inspection process
• Upon completion of processing of wood products go through rigorous
testing to finally put on the market, mainly the detection of flexural strength
testing, thermal testing, water thickness swelling test, formaldehyde
emission testing, dimensional stability test, heavy metals testing.
Flexural strength test Heat detection Water thickness testing
Formaldehyde emission detection Dimensional stability test Heavy metals testing

11. Packaging process
• The wood panels neatly wrapped in sealed cartons code together
with the real, with stick-like pad below, the first bag tile shop in the
following, and then wrapped carton good wood board placed on the
bag, the bottom and side wrap, then a wrap bag tile on top, add
some fixed angle tied with rope solid.
