Demattia Flex Tester

METLOR De Mattia Flex Tester has a set of grips to hold test specimens in two tiers with their holding faces lying in the same vertical plane. Holding one end of the test specimen in a fixed grip and the other end in a reciprocating grip provides the flexing and unflexing action. The set of grip has two fixed grips and one large reciprocating grip positioned between them in order to flex half of the test specimen while the other half is being unflexed. The reciprocating grip is slide on hardened and ground rods made of high carbon steel. The reciprocating motion is provided by an eccentric and linkage mechanism driven by an electric motor through V-belt and pulleys. A six digit electronic counter is provided for indicating the number of the test cycles undergone. The equipment is built on a rigid fabricated base plate and finished in metallic painting and bright chrome/zinc plating to give it a corrosion resistant finish. Molding dies for preparing test specimen, and jig and punch assembly for making an initial crack in test specimen for crack growth test are available as optional accessories.
