Information that must be known for purchasing impact testing machines

After more than 10 years of experience, the technical department of Jinan Hengsi Shanda Instrument Co., Ltd. reminds the majority of users to chooseImpact testing machineThere are many things to pay attention to, and you need to understand the following information to understand the selection criteria more.

This machine can use rubber, plastic, plastic, film, textile, fiber, nanomaterial, polymer material, composite material, foam material,

Packaging tape, paper, wire and cable, fiber optic cable, safety belt, safety belt, leather belt, footwear, tape, polymer,

Spring steel, bearing steel, stainless steel (and other high hardness steel), castings, steel plates, steel strips, non-ferrous metals, automotive parts,

Alloy materials and other non-metallic materials and metal materials are subjected to tests such as tensile, compression, bending, tearing, 90° peeling, 180° peeling, shear, adhesion, pulling force, elongation, etc.

The battery is fastened to the test equipment with rigid mounting parts that can support all mounting surfaces of the battery, each battery should withstand a total of three equal-order impacts. The impact should be applied in each of the three mutually perpendicular directions unless the battery has only two axes of symmetry, in which case the test is only performed in both directions. Each impact of the impact tester must be applied to the normal direction of the battery surface. Each impact of the battery must obtain such acceleration, that is, at the initial 3ms, the small average acceleration is 75g (g is the local gravity acceleration). The peak acceleration should be between 125g and 175g. The battery should be tested at 20±5°C (68±9°F).

Impact testing machineThe concept and use test machine is a precision test instrument that determines the mechanical properties, process performance, internal defects and verifies the dynamic imbalance of rotating parts under various conditions under the environment of Jinan Hengsi Shengda Instrument Co., Ltd. In the process of studying and exploring new materials, new processes, new technologies and new structures, the test machine is an indispensable and important testing instrument. It is widely used in related laboratories of machinery, metallurgy, petroleum, chemical industry, building materials, construction engineering, aerospace, shipbuilding, transportation, and other industrial departments, as well as colleges and universities and research institutes. It plays an important role in the effective use of materials, improving processes, improving product quality, reducing costs, and ensuring product safety and reliability.

In the test samples, the mechanical properties of the material are tests such as tensile, compression, bending, shear, torsion, impact, fatigue, creep, durability, relaxation, wear, and hardness. Tensile test is also called tensile test. The instruments generally used are universal material testing machines and tensile testing machines. They mainly apply loads slowly at both ends of the sample, causing the working part of the sample to be subjected to axial tension, causing the sample to extend in the axial direction, and generally until it is broken. Tensile test can be used to determine the tensile strength and plastic properties of the material. Tensile samples must comply with the tensile test requirements for different materials by relevant national and industry standards. Tensile test curve Stress-strain tensile curve.
