Ultimate screwed part provided by
TANGE’s stamping built-in progressive die

Pressed parts with screws are tapped separately either manually or automatically, by deploying a tapping machine after stamping. Since the processes are separate, there are issues of quality stability, e.g. tapping omissions, and production stability, e.g. differences in processing costs and delivery times according to the production volume.
Tange Manufacturing Co., Ltd. (TANGE) has developed an original progressive die with a built-in tapping device that solves these problems simultaneously. Since our tapping process is completed during stamping, we are able to manufacture parts with guaranteed superior quality and consistency. In addition, we also handle knurled parts that apply this built-in progressive die to mass-produce knurled press parts with guaranteed quality.
This progressive die with a built-in tapping device performs simultaneous compound processing by combining tapping and knurling area in addition to the conventional stamping processing areas such as punching, bending, forging, drawing, shaving, and burring. Our built-in progressive die technology enhances the functionality of the stamping parts while satisfying mass productivity.
　TANGE's progressive dies with built-in multi-tasking provide a stable supply of high-quality stamping parts with high cost performance.

TANGE’s original built-in progressive die technology

TANGE’s original built-in progressive die technology 1 Tapping and knurling
in stamping process
  • Highly stable quality guaranteed by eliminating additional tapping or knurling separate process.
  • Shortest processing time realised by deploying built-in original stamping die.
  • Contribute VE while maintain the functions and/or specification.

TANGE’s original built-in progressive die technology 2 Small as M1.2 tapping
in stable production
  • Highly sophisticated mould system realised from M1.2 to M6 tapping with stable quality.
  • Capable to produce max. 6 directions tapping in a part.
  • Smaller than 50*50 mm size are applicable.

TANGE’s original built-in progressive die technology 3 Highly sophisticated
mould unit design
  • TANGE’s original built-in moulds are 100% tooled in-house to maximise the cost efficiency.
  • Unit combination progressive die system is deployed, thus short mould tooling ead time is realised.
  • Mould unit composed according to our standard to ensure stable production.
