From the moment we receive raw material until your order leaves our door, we engage in step-by-step quality checks that insure critical tolerances have been met. Our quality control is enhanced through the use of computerized plotting, memory storage, printout conformation, and data processing. Inspections are automated for tighter control in critical areas including: bend angles, accurate straight surface positions, elongation, spring back, stresses factors and repetition.
