<p>PURPOSE:To mold a sheet having uniform thickness and surface roughness by a single mold. CONSTITUTION:A first manifold part 4 distributing the molten resin flowing in a mold main body 1 in a lateral direction, a land part 5 capable of adjusting the flow rate of the resin in the extrusion direction in the lateral direction through a choke bar 2, a second manifold 6 uniformizing the pressure of the resin in the lateral direction and a lip part 7 controlling the shearing force through a cap 3 are successively formed.</p> |
