Quality Comparison Table of Segment Screw & Kneading Disk in China
對比項Comparison Item | 上海原元康Shanghai Omega | 一般制造商Generic Manufacturer | |
制造材料 Material | 元件的制造選材 Manufacturing Material for Screw Element & Kneading Disk | 根據用戶工況條件可以多種選材,鋼材供應商可靠Varieties of material can be choosen based on customer's wong condition, steel supplier is reliable | 一般采用滲氮鋼，模具鋼和不同種類的高速鋼等，鋼材供應商良莠不齊Generally made of nitrided steel, mold steel and different kinds of high-speed steel，steel supplier is uneven |
產成品硬度 Finished Product Hardness | 硬度控制范圍Hardness Cool: HRC58～62 | 因材料質量導致硬度不穩定Hardness is not stable because of the quality of materials | |
單個長度較長的螺紋元件內花鍵Internal spline of a single longer screw element | 全長度滿鍵，強度高，易拆卸 Spline through full length that element strength is high | 中間部分無內花鍵，元件強度低 there is no spline on the middle of element that strenth is low | |
尺寸公差范圍Size Tolerance Deviation | 內花鍵底徑尺寸公差 Size tolerances of spline ID | ≤0.04mm | ≤0.20mm |
外徑尺寸公差 Size tolerances of OD | ≤0.025mm | ≤0.05mm | |
螺棱底徑尺寸公差 Size tolerances of thread ID | ≤0.04mm | ≤0.10mm | |

1）我公司對范圍內多家平行雙螺桿擠出機制造公司和塑膠配混終端用戶公司所積累并提供的上述對比數據表示誠摯的感謝 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）我公司螺紋元件的制造材料更有多種選擇，以滿足不同工況條件的需求。例如我們采用芬蘭美卓公司的高釩WR5粉末冶金鋼制造的螺紋元件，其理論使用壽命是高速鋼的二倍以上。更有以粉末冶金鋼作為元件工作面合金而芯部則采用韌性鋼材所制造的雙金屬組合元件供用戶選擇，例如用以耐工況條件的組合螺紋元件，我們采用了外部是C276粉末冶金合金鋼而芯部則是316L的雙金屬鋼材制造螺紋元件，交付用戶使用后反饋相當滿意 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）歡迎任何有特殊工況條件需求，或較高品質需求的詢問和探討Any more higher quality inquiry, welcome to discuss, and it is certain that it could be made according to customer”s drawing after analysis.
