Definitions

  • the inventor has therefore, invented this method which is able to mass and economically produce screwnut.
  • the present method generally comprises the following step.
  • the first step of this invention is to cut precisely raw material and conveyed into a forge machine which implements five steps at each movement.
  • the five steps are shearing, trimming, pressing, extrusion and form.
  • the first step, shearing is to shear exactly size required out of the raw material then conveyed to the trimming processing which trims the granual finish out from the raw material and also to buff pulish the shearing end of the material.
