The mordazas of coin manual of precision fulfil with the requirements of Nadcap

The new series of mordazas of coin manual developed by Instron combines reliability with big precision and alignment of samples repetible. This characteristic does them able to fulfil with the strict requirements Nadcap AC7122-1 (for materials no metallic) and AC7101 (for metals), commonly used in the industry aerospacial.

Whereas the mordazas of coin Instron 2716-028 are designed for a nominal strength of 100 kN, the mordazas of coins 2716-030 can reach maximum loads of 250 kN. This peculiarity turns them into the ideal election for the demanding tests of tension of a big variety of materials like metals, polymers reinforced with fragile fibres of high resistance and other rigid materials.

His enclosed design avoids the penetration of dirt and of fragments of the materials of proof. The symmetrical closing of the mordazas has achieved through an adjustable mango of safe and easy ratchet to use, and the strength of closing applies only when it has begun the proof. To measure that advances the essay, the action of coin them allows that the strength of the mordazas increase in proportion by force applied. The wands of advance allow that the mordazas are used inside a camera of temperature Instron, providing a wide range of temperatures of proof, between the -80 °C and the +250 °C, without need to change pieces or lubricantes.

These include adapters ‘piggy back' and elements to mount probetas of distinct types of essays (for example compressesion and flexión), which can join to the mordazas without need to disassemble them. In addition to this, there is available mordazas with different superficial structures, that can be changed in seconds without the utilisation of special tools. The helps of centred ‘Specime Centering Stops', available of optional way, contribute an exact positioning of the samples.
