<p>PROBLEM TO BE SOLVED: To enable manufacturing of extrusion moldings whose dimensional accuracy is upgraded. SOLUTION: This manufacturing device for extrusion moldings is equipped with speed adjusting means 6A, 6B for adjusting the speed of a molding material Mr to be flowed into an extrusion mold 2 and speed measuring means 9A, 9C for measuring the speed of the molding material Mr to be flowed into the extrusion mold 2, installed at specified positions in the extrusion mold 2, and draws out extrusion moldings P in succession. In this case, the speed adjusting means 9A, 9B are controlled so that the measurement value of the speed measuring means 9A, 9C are at a specified constant level.</p> |
