Carrying its legacy for over 60 years, we have been continuing to manufacturing large special screws (large cutting screws), long shafts, and twin screw extruder spline shafts. Our pursuit of contributing refined products created by the exquisite technology has been bringing satisfaction to the customers. Try using our products, and we guarantee that you will be satisfied with the quality of these. By all means, please contact us to talk through your business needs.
The most critical element for screws is its precision. We are proud of its outstanding accuracy in meeting our customers requirements with our perfect precision. A screw is vital to make a machine move functionally and we believe that a screw’s precision can be the key to the development of domestic and global market. We continue to commit ourselves to being one of the world excellent screw manufacturers and believe that we are able to contribute to the planet by creating comfort although the task assignment given us is rather partial.
We would like to explain hereunder about our technology maintained for over 60 years, based on which we have been manufacturing screws to satisfy global customers needs. Also, below you will find our actual performances as well.
- Triangular Thread （Metric Thread, Inch Thread, Unified Thread）
- Trapezoidal Thread （Metric Trapezoidal Thread {Tr}, 30-degree Trapezoidal Thread, 29-degree Trapezoidal Thread ｛TW｝
- Square Thread
- Buttress Thread
- Multi-Start Thread
- High Lead Screw
- Cross Screw
- Heat Treatment (Induction, Carburizing) Grinding Screw
High accuracy is feasible for all spec screws.
The backlash of external and internal thread can be adjusted with high accuracy.
A thorough check of screw contact is also conducted in the matter of sliding screws under high load.
Based on our performances and know-how accumulated for over the years, a shaft with the maximum length of 20m and maximum weight of 30 tons is possible to be fabricated with a high degree of accuracy.
As for the long shaft fabrication, distortion of materials has been a constant challenge for us. The important point is to not only fix the distortion but to also chose the appropriate materials and the heat treatment. Please also visit our company for the purpose of material sourcing.
Not to mention shaft fabrication, spline gear cutting and its fabrication is possible up to maximum 10 meters with various shapes like involute, square and hexagon.
