1.Screw fixing by servo motors,while its torsion & speed can be sdjusted precisely according to the request. 

2.Precise Screw Fixing: The machine can lock 3 screws in total. Before locking the screws, the shoes can be fixed with the mold to avoid the shoes shaking and the screws being inaccurate; 

3.Automatic Screw Feeding/Dispatchng:With the screw loader,the screw can be automatically dispatched,feed and fixed in the heel;

4.Saving Labors:No need to punch holes on insole,can directly put screws in the heel,based on the output,can save1-2 workers; 

5.Saving Materials:With this machine,heel break is much less comparing to manual m/c,thus no waste of heels; 

6.Saving Consumption Material:The m/c is with screw driver protecying system,while with manual m/c,the screw driver is easily/frequently broken;

7.More Stable Heel Fixing:The m/c is turning the screw in the heel by one cylinder,while its pressure and torsion can both be adjusted.The head inlination can be adjusted based on different heel size too;thus the screw can be more stably fixed on the heel; 

8.Easy Operation:Can close any screw you want,and the screw sequence can also be set based on request; 

9.DecreasingtheOperator's Workload:Easy operation,convenient adjustment,low noise,greatly decreased the operator's workload;

10.Opltional:Use 2 different size screws simultaneously.
