5. Production Capacity & Quality Control
 
Our convered area is 20000 square meters and the construction area is 18600 square meters;
• There are more than 100 sets of advanced processing equipments in our plants. Such as the CNC thread grinding machine, the CNC screw milling, the CNC kneading block grinding machine, the CNC milling,the 4 axis machining center, the automatic deep hole grinding machine, the CNC lathe ,the CNC surface grinder, the CNC cylindrical grinder, the CNC sawing machine, the laser marking machine, the vacuum quenching furnace, the vacuum tempering furnace and so on . Ultimately,We become one-stop manufacturer for all services and thereby ensure the good quality through the internal control.
• Therer are also some advanced testing equipments, such as the metallographic analyzer, the Taylor roughness meter, the Japanese Mitutoyo height gauge, the CMM, the Rockwell hardness tester, Vickers hardness tester and some other advanced testing equipments, which ensure the products 100% controllable;
• 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.
