INSPECTION AND TEST OF PA TC-BALL

Prime Alloy Mfct.(Shanghai) Co.,Ltd (PA) has most advanced quality control instrument for TC ball production ,including each process from materials to finished ball. The Inspection and test items are Ball Dimension, Structure, Hardness, Surface Roughness, Surface defect, Crush Force and Chemical Composition. For TC Ball mainly used in ball pen, the test between ball and tip /ink is useful to improve ball application ( PA welling to do this test with you ) 。

Surface quality of roughness is an important characteristic of balls. AFM can get micro-surface 3D character and Ra/Sa value. It’s precision 0.1nm.
Ra------- Line Roughness AFM
Sa------- Area Roughness
Roughness Sa will get more ball surface information than Ra only one line
