(1) plastic sheet production equipment barrel temperature on each section from the feeding section to the barrel and forming the mold junction temperature gradually increased.
(2) Molding mold temperature slightly higher than barrel temperature. High temperature control at 5 --- 10 ° C. The temperature at both ends of the mold slightly higher than the mold temperature, higher than the temperature control at 5-10 ° C.
(3) into the film form, the middle roll of the three rolls on the surface of the roller should be in a horizontal plane with the lip under the lip mold; lip end surface parallel to the middle roller centerline, 50 ~ 100mm apart.
(4) Die lip clearance should be slightly less than or equal to the thickness of plate products, die lip gap should be slightly smaller than both sides of the lip gap.
(5) plastic sheet extrusion machine Note that the three-roller face roughness R should not be greater than 0.2pm. Clean the roller surface with a hard steel knife scratch roller surface, should use a copper knife to clean the surface of the residual material.
