Pursuing the ultimate air stamp hammer technology

Planning optimal manufacturing processes and passing down technologicalexpertise
The technologies underlying die forging using air stamp hammers come together in the dies that make this work possible and the workers who carry it out. Our strengths lie in our ability to design products and dies based on a vision of the best possible manufacturing processes and our ability to pass down technological expertise to the employees who make up our stable workforce.
Die forging
Die forging (with an air stamp hammer) is a manufacturing technique in which heated materials are forged in order to enhance their mechanical properties by improving their structure on an atomic level and to create the desired shape while eliminating the need for certain mechanical processing steps or reducing the number of man-hours required.
Advances of die forging include:
  • Saving materials, which can be formed into shapes and dimensions that closely approximate the productfs final shape.
  • Eliminating or reducing machining processes using machine tools.
  • Allowing mass production of products in shapes that would be difficult to machine using conventional means.
  • Yielding products with a dense atomic structure that are free of internal defects.
  • Yielding products that exhibit little variability in mechanical properties such as tensile strength and hardness.
  • Yielding grain flow (metal flow) that mirrors the productfs shape, increasing resistance to repeated bending stress.
  • Yielding products with little dimensional variability.

01 Product designOur product philosophy, which focuses on strengths such as gforging from castingh and forging one-piece welded structures, start with a design stage that unfolds from the customerfs perspective.
We visualize the shapes that would provide competitiveness from a variety of standpoints, including price and quality, based on the current product drawings we receive from customers and study manufacturing proposals to implement them.

Die designAfter creating a manufacturing proposal, we apply it to forging drawings. Next, this data is sent to our in-house die design department, which carries out a variety of quantitative analyses based on the forging drawings. The results of those analyses are used to create die machining programs and die drawings.

03@Die manufacturingDies are then produced in our in-house die Factory based on those programs and drawings. Our strength lies in our ability to carry out the full range of processes in-house, from forging proposal creation to die production and forging. As a result, we are able to dramatically reduce the manufacturing lead times that are usually associated with die-forged products.
05 Quality assuranceNext, manufactured die-forged products move on to final shipping inspections during which certified inspectors carry out final checks at a facility that has received ISO and a range of other industry certifications. This rigorous system of checks ensures our ability to ship only high-quality products.
