- This paper provides technical support guidelines that address problems related to nail clipper progressive die for Three Seven Inc., also known as “777” in the global beauty supply market. The company’s nail clippers have not been recognized as the best of their kind because the cross sectional areas on the sides of these multipurpose nail clippers that are more recognized in the global market than in Korea are not even and have a large fracture angle and rough surface. Although 24-hour barrel work is relied upon after heat treating a nail clipper product that is produced from die to achieve even cross section, technical support for die is still needed. In this regard, clearance is revised, structure of blanking stage is changed, and strip layout drawing is modified. High-temperature tempering is conducted when constructing die in order to eliminate corrupted layers and residual stress. The results of this technical support for die through the aid of the heat treatment technical support business unit of Kongju National University showed 2.5 times and 1.3 times improvement in die repair/maintenance cycle and die life span, respectively, with a 20% increase for both quantity produced and sales. In addition, the defect rate has significantly decreased from 5% to 0.1%.
