Technical Solutions for Cold Forging
Combined with an optimum steel material, "x method" cold forging technology makes the impossible happen
Cold forging prototyping (forging method simulation)
At our laboratory, cold-forged parts can be prototyped to make sure their forging load and shape are designed properly.

FEM cold forging analysis (numerical analysis technology)
If a customer wants to manufacture its part by (1) cold forging, instead of hot forging, to obtain (2) higher strength, we will run FEM analysis to calculate and estimate maximum stress in the work, and recommend a steel material with industrially reproducible workability (e.g., deformability, crack resistance) so that the part can be made in the customer's actual manufacturing process.
