Spend for 180-210 ° of c.
Due to said structure, during floor base material shapes, the shape of the particularly scleroma cortex on material main body surface
Become, in extrusion body, upper and lower pressuring template operates to the base material just spreading of shape and is even more important, and wherein substrate material enters extruding
After shaping mechanism, limited the squeezing passage passing through by it and can form it into base material just shape, wherein first each position of shape of base material is close
Degree is of substantially equal；In order that the surface of the first shape of base material form scleroma cortex it is therefore desirable in the short time surface to the first shape of base material
While cooling, apply uniform extruding force；Pass through the upper and lower pressuring template of pressure water slug therefore in this technique, make upper and lower pressing mold
Plate, under hydraulic blow, is equably squeezed in the surface of the first shape of base material；Wherein corresponding press water is set in extrusion body

Upper and lower pressuring template is implemented equably to implement to roll action it is ensured that the base material scleroma that just shape surface is formed on the surface of the first shape of base material
Skin thickness is uniform.In extrusion body, base material is just acted on by grinding pressure on shape surface while being cooled down, by
In base material just the surface of shape and center portion influenced by different forces so as to base material just the density on shape surface promptly increases and is pressed
Real, and the density of its center portion is constant or small change occurs, thus being just formed with scleroma cortex in shape surface in base material, and this is hard
Skinning cortex is fine and close；The density in the wherein first centre of form portion of base material is relatively small.In extrusion body, to base material, just shape rolls
During, upper and lower pressuring template is particularly important to the extruding force of the first shape of base material, if this extruding force is excessive, makes the first shape of base material
Surface and its center portion are subject to essentially identical active force simultaneously, are also the formation of the extrusion molding to the first shape of whole base material, and no
Method forms the larger scleroma cortex of density on the base material just surface of shape, if this extruding force is too small, base material is just suffered by shape surface
Extruding force not enough it is impossible to just the surface of shape carries out local and is compacted by base material, also just cannot form scleroma cortex；Therefore this technique
