1）我公司对范围内多家平行双螺杆挤出机制造公司和塑胶配混终端用户公司所积累并提供的上述对比数据表示诚挚的感谢 the data above based on supplied report by some OEM companies and end user all over the world specialize in making Co-rotating Twin-screw Extruder.
2）我公司螺纹元件的制造材料更有多种选择，以满足不同工况条件的需求。例如我们采用芬兰美卓公司的高钒WR5粉末冶金钢制造的螺纹元件，其理论使用寿命是高速钢的二倍以上。更有以粉末冶金钢作为元件工作面合金而芯部则采用韧性钢材所制造的双金属组合元件供用户选择，例如用以耐工况条件的组合螺纹元件，我们采用了外部是C276粉末冶金合金钢而芯部则是316L的双金属钢材制造螺纹元件，交付用户使用后反馈相当满意 More material can be choosen for element manufacturing, such as high-vanadium powder steel WR5 from Finland, the theoretical opration life of which is more than twice times of high speed steel, and other varied of bimetallic steel bar...
1）欢迎任何有特殊工况条件需求，或较高品质需求的询问和探讨Any more higher quality inquiry, welcome to discuss, and it is certain that it could be made according to customer”s drawing after analysis.
