Method of making a double-screw extruder |
摘要 |
To form the housing of a double-screw extrude, the housing body or a segment thereof is provided with auxiliary bores along a segment of the housing at which the hardening material is to be thicker or a hardening material is to be provided. The screw-receiving bores are then formed and overlap each other and the auxiliary bores and the hardening material is provided at least in the auxiliary bores by a division process, preferably a hot isostatic pressing (HIP) process. |
