Method for Manufacturing Blades of Wind Energy installations, as well as for the manufacture of a Core mold for these

摘要

1. The procedure described in this document is to manufacture a mold core to manufacture a single wind energy facility drum pallet. The procedure includes the following steps: providing a flexible hollow body, such as a blown thin film tube, inserting the hollow body between at least two cast parts whose positions are mutual,Before or after the hollow body is inserted between the forming parts, and after the hollow body is filled and input, a by-product is generated in the hollow body, so that the hollow body rotates, forming a negative rotor, and filling the hollow body with bulk materials. This document also refers to the procedure for the generation of suppression between the formed part and the die core.
