GenFlex tests the ability of rubber products to withstand repeated flexing without developing cracks is of prime importance where such products are used in conditions undergoing repeated flexing.
Flexing endurance of rubber products is determined by simulating in laboratory the action of flexing repeatedly under standard conditions of speed, mode, and degree of flexing.

The following industry standards are typically followed when testing with the DeMattia Flex Cracking tester:
ISO 132, ISO 6943, ASTM D813, ASTM D430-B and JIS K_6260
Most commonly, rubber sole material is used in a DeMattia Flex tester. Due to the fact that the rubber soles are being used daily and coming into contact with roads, dirt and other elements, they endure the maximum level of flexing. It is the friction from all the flexing that can lead to a surface crack which can lead to failure of the rubber compound.
While rubber has an extremely high strength rating, it also exhibits some faulty characteristics after being exposed to heat, cold weather and humidity/temperature changes. After being exposed to these elements, it is common for a crack to develop on the surface and these cracks have a tendency to continue to grow. DeMattia Flex Cracking can help to estimate the rubbers lifespan after a crack has formed in the materials surface.
Up to 6 specimens can be tested at one time after setting the frequency per your industry standard.
The specimen must first be created in the size required per the industry standard. NextGen can supply the ASTM D430, Method B cutting dies along with the D813 mold required to perform these tests. ISO moulds can also be provided as a custom order.
The DeMattia test allows the operators to analyze the fatigue-cracking properties of the material in question. It provides a picture of the potential lifespan of the material when being used in its service application.

GenKron is used together with a special balance for testing the abrasive consumption of materials. The measurements are done through volumetric loss of a rotating specimen exposed to the action of a standard grinding wheel. It is especially suited for testing harder materials such as shoe soles, tires and other rubber materials.
GenDin, is designed to conform to the ASTM D5963 and IS0 4649 standards. This top quality and highly popular abrasion tester will allow you to measure the abrasion resistance of rubbers (vulcanized thermo set rubbers and thermoplastic elastomers) that are subject to abrasive/frictional wear on their actual service. Since wear is always a result of abrasion, different test methods have been developed for the simulation of long term wear.
The machine is used to test the dyeing of the fabric, and the fade degree of the leather after dry or wet rubbing. The test method involves the specimen to be fastened to the base of the crocking meter and rubbed with an abrasive hammer attached to a wet or a dry cloth under controlled conditions. The transfer of colour is then measured using a scale to evaluate the rating of the specimen's dyeing grade.
GenFreeze is specially designed to test the characteristics of various materials in a cold environment to ensure suitability for use in a cold climate. Based on the testing demand, adjust the beater and flexing grip, then load to the desired position. It can be used to test rubbers, leather, and plastics, PU leather etc. The unit can be adjusted to meet different requirements.
GenDale is mainly used to test shoe fabric, shoe lining, and many other types of shoe related materials. The unit can test up to four specimens at the same time for abrasion. The fabric specimen is measured by having rubbing applied on it via a complex direction of back and forth motion. The accuracy of abrasion strength is determined by the specific number of cycles conducted until a hole appears in the test area of the fabric specimen.
GenMooney is a viscosity testing machine is applied to measure the viscosity of the unmixed or mixed unvulcanized natural rubber, synthetic rubber and regenerated rubber .This tester has many functions such as fast warming, maintaining temperature, data stability, etc. It is equipped with an automated calibration feature for a simple data calibration of each experiment.
GenNBS is used to test the abrasion resistance of vulcanized rubber or other rubber compounds. It is commonly used for the soles and heels of footwear. It has an intelligent power failure recovery system. The unit conducts measurements through volumetric loss of specimens exposed to the action of a normalized abrasive medium secured to a rotations cylinder.
This machine is designed to get the characteristic curve and characteristic parameters of rubber vulcanization by measuring the applied moment of rubber to the oscillating dye body. NG-ODR rotor-free vulcameter has an excellent stability of results. The data and diagrams can be used as a reference for development, research and production quality.
GenSalt is designed to test the surface of different materials for resistance to corrosion. The unit is commonly used to test coated materials of a metallic nature in a controlled corrosive environment. The test can be used on rust-proof painting, anodizing, electroplating and rust-proof of grease. The machine imitates expedited corrosion process via salt spraying on a given test sample to identify the corrosion (oxides) resistance. Test results are based on the longevity of time a material can resist visible corrosion on the test sample.
The machine is designed to test the abrasion resistance of fabrics and metals. The abrasion of fabrics is tested when the specimen is pulled over the frame and rubbed against an abradant over a curved surface. The number of cycles, also known as double rubs, conducted on the specimen before the fabric shows visible wear is used to determine the rating of abrasion.
GenRebound tests the resilience of rubber compounds. The machine must be adjusted in a horizontal position and the plunger raised at a specific height. The plunger is then released onto the specimen for a given number of impacts. The measurements are based on the 4th, 5th, and 6th impacts. The average of the three (3) measurements is then calculated for the test result. The machine is highly useful in production of compounds designed to absorb vibration or shock according to the ASTM standards.
GenTaber used evaluate abrasion resistance. It can conduct tests on a wide range of materials such as: cloth, paper, paint, plywood, leather, tile, glass, rubber etc. It tests the specimen by rotating it while in contact with the grinding wheel and applying the required pressure. The Joss of weight reflects on the change in weight of the specimen. The unit also has an intelligent power failure recovery function.
