We stamp 1.4 billion pieces per year with 450 various designs by shallow drawing.
Shallow drawing is our main techinique we have been cultivated since 1975.
Our excellent dimensional stability can contribute to achieve zero-loss assembly process at customer side.
Deep Drawing
Our deep drawing products are widely used for the battery cases for the device which the long-life and high
reliability in a harsh environment is required such as Smart Meter or Sequrity Device.
We do 100% appearance guarantee for the problem regarding inclusion of the stainless steel.
Cold Forging
We achieve "Net Shape Processing", which is the ultimate forging process and
minimize processing waste and make effective use of limited material resources.
Would you like to reduce the cost environmentally friendly by switching from
cutting to our cold forging?
Coining
In addition to the control of the residual thickness of
explosion-proof valves, we also incorporate the measurement of opening
pressure into the mass production process to guarantee the quality of safety
parts from the functional aspect as well.
Engraving your brand logo on the surface of the battery can is also possible.
It is installed in the same die as the drawing die and processed without slowing down.
Insert Molding・Battery Lid Assembly
We help customers reduce assembly man-hours by our integrally molding of plastic parts such as insulators
and metal stamped parts.
Also we are now working on the header assembly (sealing body of the batteries) process.
Please feel free to contact us.
Die Design
Before processing, we set the conditions of the press die by analysis simulation.
Create drawing data with 3D CAD and use them for die parts production.
We achieve cost reduction and shortened die manufacturing lead time.
Press Die
Progressive Die
Progressive dies have multiple processes in one die, and the continuous processing speed is fast, so it has
excellent production efficiency.
Also we have some equipments that integrates a press machine and a washing machine together.
Transfer Die
In transfer dies, multiple single-shot are processed side by side in a single press machine.
Good yield of raw material, and can handle the larger parts.
Insert Die
It is possible to create the parts that integrate metal parts and resin parts.
Reduce customer assembly man-hours by processing lids for such as lithium-ion batteries, etc.
