Process

COLD HAMMER FORGED RIFLE BARRELS AND BLANKS

 

The process of Cold Hammer Forging barrels has been proven for decades to produce the most accurate, longest lasting rifle barrels obtainable.  Cold Hammer Forging of barrels is achieved through the application of extreme mechanical and hydraulic pressures at opposing angles by carbide or hardened steel hammers. During the hammering process, a precision ground carbide mandrel is inserted into the bore shaping the hammered material around the mandrel to create the rifling. 


The preparation and care of the pre-forged blank by SAND Hammer Forging equates to impeccable barrel straightness and rifling quality during the Cold Hammer Forging process.  This attention to detail improves the quality of the bore in the finished forged blank.  Because of this direct relationship between the precondition and end product quality, SAND Hammer Forging, maintains strict tolerances in bore surface finishes and overall bore concentricity prior to the forging process to ensure its rifle barrels are as accurate as possible. 


All SAND Hammer Forging, Inc.  rifle blanks are made from start to finish in our facility located North Carolina.  Focused on quality assurance to maintain consistency and consistently excellent products;  SAND currently contracts to various turning companies to provide extraordinary quality and bring the expertise and versatility to contour standard and custom OEM designs.

  

SAND Hammer Forging offers a protective Melonite coating that surface-hardens the metal.  Also referred to as Salt Bath Nitriding, this treatment produces an extremely hard, slick surface on steel that resists carbon adhesion and increases corrosion resistance, making for easier cleaning and maintenance.  By utilizing this process, which does not add any material to the barrel or rifling, the premium quality of manufacturing is allowed to shine directly through to the finished product.
