					Tungsten Carbide Shear Blades

Ultra long life blades

                         For many years Shear Blades from Emhart
                         Glass have set the industry standard for
                         consistent accuracy and durability over a wide
                         variety of gob-cutting applications. Now the
                         family of blades is being extended with the
                         introduction of ultra hard Tungsten Carbide
                         blades, which offer an unsurpassed working
                         life span, some 5 to 10 times longer than that
                         of steel blades.
                         Tungsten Carbide shear blades from Emhart
                         Glass are available in the two industry
                         standard sizes, together with a variety of
                         shapes for special applications.

              Reduced downtime                                                                       Material: A composite of Tungsten Carbide,
              Plants with long-running jobs particularly appreciate the                              Cobalt and small amounts of additional alloy
              advantages of much longer blade life, resulting in fewer stops                         specially developed to resist the challenging
              to change blades. In this way, unnecessary downtime and                                conditions in container glass production.
              disturbance can be avoided.

              The hardness of the blade material enables a higher initial
              sharpness compared with metal blades. The excellent high                               Weight: 121g (small blade), 176g (large blade)

              Once set up correctly in the shear mechanism, Tungsten

              exceptional wear resistance and fracture toughness.
