Cost reduction in material expenses by using wire materials, pipe materials, and overseas materials! Introduction of VA case studies.
We would like to introduce a case of "changing from cold forged hollow bolts to pipe material." We switched the hollow bolt, a product with a total length of 100mm, from machining to cold forging using a value analysis proposal, but we encountered hardness issues. Drilling holes in the longitudinal direction of the forged product was difficult due to the customer's required hardness. We reduced processing time and steps on the machining equipment while lowering the material quality, but ultimately improved the final challenges. By using pipe material instead of wire material and utilizing overseas materials, we successfully reduced material costs and increased hardness as per the customer's request. [Focus Points] - Hardness as per the drawing - Reduction in material costs - Automation *For more details, please refer to the PDF document or feel free to contact us.*
