3 steps to understand the materials attached to the test machine

useUniversal testing machineThe users of the equipment understand that the different tests performed by the test machine are achieved through fixtures. The following are 3 introductions to the attachments by Jinan Hengsi Shanda Instrument Co., Ltd.:

1. Generally, high-quality medium-carbon steel and alloy structural steel are used to add its mechanical functions through appropriate heat treatment processes. Sometimes, non-ferrous metals such as aluminum alloys and special metals are used in order to reduce the weight. Sometimes forged structures (cast steel, cast aluminum, etc.) are also used.

2. For some fixtures with small experimental force, the surface in which they come into contact with the sample is used to use soft rubber leather. (For example: the clamping surface of plastic film, fiber wire and other samples.)

3. For ordinary metal and non-metallic specimens, the jaws of the fixture are in direct contact with the specimen. Generally, high-quality alloy structural steel, alloy high-carbon steel (or low-carbon alloy steel), cold-work mold steel, etc., and their strength and wear resistance are added through appropriate heat treatment processes (quenching, carburizing and quenching, etc.). Sometimes special steel is also installed at the jaws, or gold steel sand is sprayed on the surface of the jaws.
