[ Problem Point ]
It was necessary to harden only specific parts of metal components to improve localized hardness, but conventional methods heated the entire part, increasing the risk of unwanted deformation.
[ ⇒Kaizen Point ]
By using the halogen point heater, it became possible to apply high-temperature heating only to the required area and perform targeted hardening. This prevented unnecessary thermal deformation while enhancing the strength of the product.
