Case2 | Hardness up and cost reduction by cold forging |
Field of application | VE idea point |
・Cam cap group | ・Applicable to high strength material such as 2000 series alloy. |
Existing methodIn the existing method, it is manufactured by casting (Die-Casting), 1.Hardness is decreased from casting porosity. 2.There was problem such as the necessity of increasing thickness for hardness assurance. | New technology/New methodAluminum cold forging achieved to improve part reliability and reduce weight. | |||
