• Company passed the SGS ISO9001.2015 successfully, and we conduct the comprehensive quality planning and management strictly in accordance with the ISO9001 quality standard and management system.
• The adequate inventory can ensure that customers get the products in the first time.
• The annual production capacity of screw segments is about 8000 meters, barrels with mirror inner hole 2000pcs and 2500pcs shafts with high torque.



6. Raw material guarantee
The company has been cooperating with domestic and foreign first-line brand material suppliers for a long time, and has a strict quality control and performs regular audits and inspection of the factory (elemental analysis, metallographic analysis, ultrasonic flaw detection, etc.) to ensure a 100% qualified status.

7. Product accuracy
There are some differences between Joiner Machinery and Nanjing's production technology. Their finishing process is carried out before heat treatment, and the deformation after heat treatment is not controlled, so their accuracy is not easy to control. But our finishing process is carried out after heat treatment, which can eliminate the deformation of parts in heat treatment, so the precision is higher, and thus can achieve zero seam connection.

8. Standards  and strict management 

Each product is strictly manufactured in accordance with the ISO9001 quality management system requirements to control the quality, so that every link can be traced.
