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
