Now let us make a introduction for how to test for the stamping products of courses including the test for T nuts products.
A. touch test
With a clean cloth to clean the surface of the outer covering parts.Inspector need to wear the touch gloves along the longitudinal pressing close to touch on the surface of the stamping, the inspection method depends on the checker's experience.Abrasive grinding if necessary by detection of suspicious areas and verified, but this method is an effective method of quick inspection.
1. First of all, with a clean cloth to clean the surface of the outer covering parts, and then polished with oil stone (20 x 20 x 100 mm or greater), there is circular and hard-to-reach places with relatively small abrasive polishing (for example: 8 x 100 mm semicircle sharpening stone)
2. The selection of abrasive particle size depends on the surface condition (such as roughness, galvanized, etc.).Suggest using fine-grained whetstone.Oilstone grinding basically along the longitudinal direction, and a good joint on the surface of the stamping parts and some special place can also supplement horizontal grinding.
3. Stamping flexible grinding yarn network
With a clean cloth to clean the surface of the outer covering parts.With flexible sand nets to stamping surface along the longitudinal grinding to the surface of the whole, any pitting, indentation can easily be found.
