In-die Tapping Stamped Parts
In-die Tapping Stamped Parts, Eliminates Secondary Tapping Process


    
  

Application/features:

For most stamped parts with a tapped hole or holes in-die tapping has become the only competitive alternative to secondary tapping. Secondary tapping of stamped parts has always been far more costly than the stamping operation.

By combining stamping and tapping, Xianduan is cutting costs as follows:

  • Initial cost: the costs of building a tapping die (including the tapping unit) are usually considerably less than building a high speed secondary tapping machine. Secondary tapping machines are usually dedicated to a single part, whereas a tapping unit can be changed from die to die. This reduces the initial cost of subsequent tapping dies, making lower volume tapped stamped parts feasible for in-die tapping
  • Labor cost: by eliminating the secondary tapping operation, all labor, related handling and feeding costs are also eliminated. In-die tapping enables the press operator to produce completed tapped parts in one operation, in many cases without sacrificing press speed. Except for inspection and tap changes, the cost of tapping is reduced to a minimum.
  • Production cost: in almost all cases in-die tapped parts are produced at a far faster rate than secondary tapped parts. Now the size of the tap and material being tapped will determine the ultimate production rate of a tapped stamped part. Xianduan is running the new tapping units close to 200 strokes per minute producing millions of tapped stamped parts monthly. Whether tapping high speed brass electrical parts or larger steel automotive parts, Xianduan's tapping units have proven to be most competitive in the industry.
