Product DescriptionWe are reckoned as one of the prominent manufacturers, suppliers and exporters of reliable quality DeMattia Flex Tester. As these testers are manufactured using finest quality raw material, these have high performance and excellent corrosion & abrasion resistance. Our flex tester is highly admired in the market for its accurate results and longer service life. Moreover, our DeMattia Flex Tester is very efficient and is capable of testing six specimen at the same time.
Some specifications about the product are listed below:
The ability of rubber products to withstand repeating flexing without developing cracks is of prime importance where as such products are used in conditions undergoing repeating flexing. The flexing endurance of rubber products is determined by simulating in the laboratory the action of flexing repeatedly under standard conditions of speed, mode and degree of flexing. One of the accepted procedures is the use of DeMattia Flexing Tester. This tester provides useful information about the resistance of compounds of vulcanised rubber to flex cracking when subjected to flexing. Cracks develop in that part of the surface where stresses are set up during flexing or if that part of the surfaces initially contains a crack, it causes this crack to extend in a direction perpendicular to the stress.
The DeMattia Flex Tester consists of a set of giros to hold the test specimens in two tiers with their holding faces lying in the same vertical plane. The flexing and un-flexing action is provided by holding one end of the test specimen in a fixed grip and the other end in a reciprocating grip. The set of grips has two fixed grips and one large reciprocating gript positioned between them in order to flex half the test specimen while the other half is being un-flexed. The reciprocating grip is fitted with gun metal cushion which 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 counter with reset is provided for indicating the number of test cycles undergone.
The equipment is built on a rigid cast iron base plate and finished in hammer tone painting and bright chrome plating to give it a corrosion resistant finish.
Moulding dies for preparing test specimen and jig and punch assembly for making initial crack in test specimens for crack growth test are available as optional accessories.
