Abstract

PURPOSE:To prevent resin frm stagnating and to manufacture an extruded product provided with a homogeneous quality special form of section by a method wherein the flow of resin is divided into two at a distributing plate part and the respective flows of resin are flowed in again from the end part of a material reservoir in a material reservoir plate and joined there. CONSTITUTION:The extrusion die comprises four plates, that is, a die holder plate 9 having a material supply hole 8 and a runner groove 13 for dividing the flow of resin into two flows, a material distributing plate 7 having two flowing holes 5 and a manifold 12 for rejoining branched flows of resin, a material reservoir plate 4 having a material reservoir 3 nearly similar in the shape to an end material resevoir 10, and a die lip plate 2 having the die land 1 fitting to the sectional shape of a final product. The flow of resin divided by the flowing holes 5 into two flows is flowed again from both end parts of the manifolds 12, 11. Therefore the flow rate does not decrease or stagnate at the end parts and a homogeneous product can be obtained.
