Title:
押し出し成形された合成木材を作るためのダイおよびそれに関連する方法
Document Type and Number:
Japanese Patent JP5844415
Kind Code:
B2
Abstract:
The present invention is directed to extrusion dies for making extruded synthetic wood and methods relating thereto. The dies include adapter dies, transition dies, stranding dies, and molding dies. The adapter dies include a channel with a restricted cross-sectional area. The stranding dies include a plurality of non-uniform channels that differ in length, cross-sectional area, cross-sectional shape, or combinations thereof. The transition dies are coordinately configured with the stranding die to adjust the flow rate of the extrudate. Particular configurations of dies upstream of the molding die allow for higher compression ratios in the molding die than previously feasible. Each of the dies described herein may be used individually with standard dies known in the art. Alternatively, the dies may be used in combination to form integrated units. The dies described herein allow for making stronger, more consistent synthetic wood at greater output rates than previously possible.
